3/25 - 11:35pm - Weather Says January, Calendar Says March

A biting wind brought in much cooler air today across Mississippi and we even saw a few snow showers across northern portions of the state. As a large trough over the eastern part of the nation begins to break down we'll see temperatures in recovery mode as we head toward the weekend. If you're looking for more appropriate spring-like weather, hang on! Later this week and the weekend will certainly feature more of what you're looking for. Check out my Mississippi State University CampusConnect forecast below for your complete outlook.

2/28 - 10pm - Snow Showers Possible in MS This Weekend

As cooler air filters in overnight we'll see chilly temperatures tomorrow morning in Starkville along with cloudy skies. A disturbance rotating through the backside of a large low pressure area over the Eastern US will give us a shot at some flurries and snow showers late Friday night into the morning on Saturday. Just like a couple weekends ago, there could be some flurries flying at the MSU baseball game on Saturday afternoon. Temperatures will begin to warm a bit on Sunday and eventually we'll get all the way into the 60's for the new workweek. Your full Mississippi State CampusConnect forecast is in the video below!

2/14 - 11:55pm - A Curveball Forecast for MSU Baseball

Ready for some baseball? Tomorrow marks the start of the collegiate baseball season here at Mississippi State and the weather will cooperate... for some of the games this weekend. Friday looks good with temperatures in the mid 50's and partly cloudy skies but unfortunately a cold snap on Saturday will bring the chill for the game on Saturday as temperatures only reach into the mid 40's. Look for a bit of recovery for Sunday's double-header games. Next week brings us more rain as we're just drying out from all the rain we had earlier this week. Yuck. The only redeeming value to this will be the warmer temperatures that will accompany the system generating the rain. Get your full Mississippi State forecast in the video below!

1/20 - 2:45pm - Bitter Cold Air is Arriving Soon!

Temperatures in the 30's were common last night in West Tennessee and North Mississippi but temperatures are poised to drop much further than that tonight. A dry and relatively marginal cold front is moving through West Tennessee right now and that cold front is the first of two cold shots for the region. This will put lows down into the mid 20's in West Tennessee and lower to mid 30's in North Mississippi as cold air pours in behind the front. This cold air won't allow temperatures to rise much during the day tomorrow either, with highs in the upper 30's closer to Jackson, TN and closer to 50 down toward the Golden Triangle in Mississippi.

During the day tomorrow the second of two shots of cold air will pour in as another cold front passes by. This one will bring the über cold weather that we'll see on Monday night and Tuesday morning. The winds behind this front will be out of the north, meaning the source region (AKA where the air is coming from) for the cold air we'll see during this time will be in the Upper Midwest where they'll be below zero. While that kind of cold isn't expected, mid to upper teens will be common in West Tennessee with readings closer to 20 or 25 degrees down toward North Mississippi. A low of 16 or 17 degrees in Jackson, TN on Tuesday morning looks pretty reasonable given the intensity of the cold air spilling down. While our neighbors to the north may scoff at this being branded as "bitterly cold" in the South, this is still some incredibly cold air. Pets will certainly need to be inside during this time and people need to be bundled up as much as possible. Limit your time outside on Tuesday morning, if possible, and be sure to cover any exposed skin if you do have to be out. Temperatures during the day on Tuesday will warm to a more reasonable lower 30's in West Tennessee and lower 40's in North Mississippi.

Temperatures will moderate during the week thanks to the return of wind flow from the south. This return flow means more moisture in the air across the region. You might guess that this warmer air and more moisture will eventually lead to rain chances... and you'd be right! A low pressure system and associated upper-level shortwave disturbance will track through near the end of the week, bringing rain chances. There's some disagreement between various models over whether this will start on Thursday or Friday. The GFS model's timeline on this is posted below. My guess at this point is that the timeline you see below will be delayed by about 12 hours, so expect rain chances to creep into the region ahead of this low on Thursday afternoon and continue through the night into Friday.


It's not out of the realm of possibility that a little bit of wintry precipitation may fall on the backside of this system on Friday. If cold air flows in behind a cold front associated with this system fast enough then some of the last few rain showers could mix with or change over to a brief period of snow. The GFS identifies Kentuckiana as being the prime target for this but we all know that model has been trending too warm lately in all the winter weather events we've dealt with. So in my mind, West Tennessee is in a potential area for this mix or snow switchover to occur. We're too early for specifics on this so the forecast will have to be fine-tuned during the week. Stay warm!

12/30 - 8pm - Anyone Up for a Third Round of Wintry Weather?

With two winter weather events within a week's time in the books for Kentuckiana, it's apparently time for a third! Unfortunately the timing for this one is pretty bad. Just as folks are going home from New Year's parties in the early hours of Tuesday morning we could have snow, sleet, or even freezing rain falling in the region. The good news here is that regardless of what falls from the sky, there won't be much of it. Precipitation amounts will remain light since heavy rain and storms in the South will be stealing our moisture here up north in Kentucky and Indiana during the time of the event. As far as timing goes, a few snow showers will move through tomorrow afternoon as this system begins to move toward us. Going into the evening is when things get tricky.

As a weak area of low pressure continues to approach we'll see some warming aloft out ahead of it. This warming has the potential to turn our falling snow into sleet or even freezing rain. The GFS is leading the charge at the moment on the potential for freezing rain in Louisville as it has a layer above freezing from 4,000 to 7,000 feet at 4am on Tuesday morning that would support freezing rain. The NAM model keeps us all snow with the entire atmosphere being below freezing. Given that the models have overestimated temperatures aloft with the past two snowstorms we've seen lately, I'm inclined to think that Louisville will stay mostly or all snow. Another thing to focus on will be surface temperatures. Should they be just below freezing this snow, sleet, or freezing rain will stick to the roads and make for tricky travel on late Monday night. If they're just above freezing then only expect to see accumulation on the grass and elevated surfaces. We do have a bit of snowcover in Louisville now, so that might lean us more in the direction of below freezing instead of above for this event overnight Monday into Tuesday. We're going to be awfully close to freezing for much of the night regardless. Areas north of the city will likely stay all snow and below freezing while those areas to the south will see a wintry mix and temperatures just above freezing until the early morning hours. National Weather Service offices across the Plains have issued Winter Weather Advisories due to this system, in purple on the image to the left, but uncertainty about precipitation type and amounts in the Ohio Valley has NWS Louisville waiting for more agreement before they issue any advisories.

Like I said before, accumulations are going to be light for this event. The NAM (right) has up to an inch of snow in many areas and the GFS model has been a little more optimistic at times today with 1-3" across the area. Like the last two snow events, I'm thinking that the amount of precipitation being put out on the models will adjust upward a bit as we get closer to time (tonight and tomorrow morning). Given the trends I'm seeing right now I think we'll see 1-2" of snow in portions of Louisville and points northward with up to an inch of snow and mixed precipitation to the south. Once again... grumble grumble grumble... Louisville is right on the line between feast and famine with the snow. Southern Indiana has been the big winner with snow over the past week while folks south of the Ohio River are raising their hands in favor of more. That is, if you're a snow lover of course. So, we'll be looking to see over the next few hours how the models handle the amount of precipitation forecast, and temperatures both aloft and at the surface. Shifts in these could mean some significant changes to the forecast for many areas!

12/28 - 1:30am EST - Kentuckiana Winter Storm Number 2

Wednesday's winter storm didn't give much snow to folks in the Louisville area and instead confined heavy snow to areas of Southern Indiana. While differences in the models did exist over whether Louisville would get any accumulating snow or not, the overall situation was handled pretty well from a forecast standpoint. The highest snow report in NWS Louisville's coverage area was 7.2 inches in Washington County, IN while Louisville received a trace to a half inch.


The next storm on the heels of the last one is less than 24 hours away as a system arrives from the southwest and stays to our southeast as it moves through the region. This will start as some rain for the Louisville area but as colder air filters in we'll switch over to snow during the later evening hours. This exact time for switchover depends on how warm we get during the day tomorrow (lower 40's versus upper 30's makes a difference!) and how fast the cold air comes in. The 0z NAM that came in earlier tonight has about 3" for the city and after comparing this with other models I'm thinking this may be a number we'll see most commonly reported by Saturday morning in Louisville. Higher totals will be possible just a bit further north from Louisville.

But even as I say this there's a small fly in the ointment. The 3z RPM model is in and it has the possibility of 4-6" of snow just due east of the city and a few very small totals like this scattered throughout areas near the Ohio River. This suggests that totals closer to 4" might be more widespread than previously thought. You can click the RPM output on the left for a larger view. We've seen the trend of increasing snow totals today on the models and this run of the RPM just continues this. We'll need to watch for this trend tomorrow morning to see if other models catch on. Right now this isn't really a factor in my forecast since it's just one model. Below is my snow forecast map for the region. Realize that, like the last storm, a small shift in track or more/less cold air will change things for some folks drastically.


Also worth noting is that the Hyrdrometeorological Prediction Center (HPC) has us in a Slight Risk of a 4" snowfall (think of this like the Slight, Moderate, and High severe weather risks) while areas closer to Cincinnati are in a Moderate Risk. Expect to see Winter Weather Advisories being issued tomorrow for portions of Kentuckiana. There may also be a few Winter Storm Watches issued as well depending on if forecast amounts of 4" or more look to be more widespread. You can keep up with the latest on this storm tomorrow by following me on Twitter and Facebook. Good luck, snow lovers!

12/11 - 10:30pm - Be Careful When Wishing for Snow... You Might Get it!

With all the warmth much of the eastern portion of the nation has been experiencing lately some folks are beginning to get antsy over whether we'll be able to fall into a more winter-like pattern in time for the holidays. The cold front that rolled through earlier this week has helped to assuage some of those fears as it brought much cooler temperatures and even some light snow/sleet to parts of Kentucky and Indiana.

So... What's next? First up is a system that will move through the region this weekend as a warm one. A low will travel from the Plains to Lake Michigan and keep the eastern half of the nation warm as it spreads rain from the Great Lakes to the South. This makes sense because the North Atlantic Oscillation (NAO) will be going neutral during this time, which generally means that cold air won't be able to spill down into the Eastern US from Canada. The Arctic Oscillation will be negative to support cold air coming out of the north, but that doesn't matter too much for us when the NAO isn't negative as well.

The system behind this weekend's is the one that is drawing some concern. A low will be moving across the South during the day on Tuesday and potentially spread some snow to areas that are north of it. At this point anywhere from West Tennessee to the Louisville area is in a potential corridor for snow. This all depends on the exact track of the low and how much cold air it will be able to bring down from the north. This scenario is supported by the NAO and AO both going negative during this time. The GFS model takes the storm along the southern border of Tennessee right to the Carolinas. The ECMWF (European) model starts out with the low a little further south along the Mississippi River but has it exit off the coast in about the same location as the GFS. The low would then become a storm that would ride up to the Northeast just off the coast. With the previous system pulling up toward the Chicago area, this low will likely stay suppressed to the south. So... the broad, general nature of this low's track isn't in too much question. My preliminary (read: subject to change!) thinking is that this will be a rain to light snow situation for portions of Tennessee and Kentucky since cold air would plunge in as the system is exiting to the east. Accumulations would be very light to none.

But here's an issue. The snow cover over the Northern Plains and Upper Midwest has expanded tremendously over the past week as a storm pummeled those areas with quite a bit of snow. We're now at 31.4% snow cover over the United States. Air moving from the north over that snow won't warm as quickly as it would over bare land and the computer models generally have a difficult time resolving that. With this snow cover, the air in place over us and the air coming down from the north may be a little cooler than the computer models think it will be at the moment. That could mean more snow from this system. We're still a week away from this event so while details are sketchy, it's now obvious that this is a system to watch. This likely won't be the only storm we'll have to contend with between now and the new year since a pattern is setting up that will allow cold air to sit close by to the Ohio and Tennessee Valleys while lows track through and just to the south of the region. There's hope for a white Christmas in the region but it will depend on whether we can get enough cold air and a storm to move through just before the 25th. It'll be fun to watch!

11/12 - 2pm - A Frigid Fall Return in Progress!

The clouds are clearing earlier than expected across Mississippi, which is good news for those looking for a more picturesque day outside. Unfortunately this will not save us from an incredible drop in temperature this evening across the Golden Triangle. The cold front that came through earlier this morning is allowing northwesterly winds to bring in an arctic air mass that will help plunge us to around the freezing mark by early tomorrow morning. If you're looking for something a little warmer than that, just wait. Temperatures will break into the 60's again by Wednesday as sunny skies continue to stick around through most of the week. Your full forecast with all the details is available in the video below!

10/29 - 3:30pm - Superstorm Sandy Coming in, Cool Week in Mississippi

Hurricane Sandy is a monster storm. That goes without saying. It's about two hours from landfall as of this writing but that won't matter much due to just how incredibly large the wind field is. Tropical storm winds extend for hundreds of miles from the center of the storm making this the largest hurricane ever recorded in the Atlantic Ocean at over 1,000 miles wide. This is big by area, not by wind speed. While the winds extend for an incredible area the winds in general are at Category 1 speeds near 90 mph. For areas in the tropics this may not sound so bad but for the Northeast this is a disaster since winds rarely get up to that strength with storms up there.

Something that also may be unprecedented here is the extreme snow threat from Sandy for the mountainous regions of West Virginia, Virginia, North Carolina, Tennessee, and Kentucky. Snow totals could be 1 to 2 feet in places when this storm is said and done. The other thing to consider with the size and scope of this storm is the storm surge that continues to roll in. Places like New York City and along the Jersey shore could be dealing with storm surge totals in excess of 11 feet thanks to the pure mass of water that will be coming in with the storm. This will create coastal flooding whereas the high rain totals will contribute to inland flooding. You'll hear about this storm for years to come... 765,000 customers are without power across the Northeast already and this storm is just cranking up.

How is this storm affecting us here in North Mississippi? We're just seeing cooler weather thanks to the large trough of cold air that's in place. This trough is the same one that's ingesting Sandy making it a very unique storm and pulling it into the Northeast. This cooler air is going to be sticking around for the foreseeable future but with some moderation. Highs won't get out of the lower 60's tomorrow and we'll finally break into the upper 60's on Wednesday for Halloween. Overnight lows tonight will be of concern since they'll be getting close to freezing, which will create a chance for some frost. Your complete Starkville forecast with these details and more are available in the video below!

2/11 - 5pm - A Wintry West Tennessee Forecast

A front that passed through West Tennessee last night brought rain showers during the overnight hours and snow showers this morning across the region. These have since moved out of the area, but the snow came down in some heavy bursts at times even though there was really no accumulation. High pressure will provide the setup for a very cold couple of days with highs in the 30's and overnight lows in the teens. Yikes! Tonight could be the coldest night of 2012 so far, which really isn't saying much since we've been pretty mild as of late.

Monday's forecast is flat-out complicated. Warm air overriding the retreating arctic air mass in place from this weekend will set the stage for a storm that could put down snow, sleet, and even freezing rain. Most indications are that this will start off as snow across most of West Tennessee on Monday afternoon as the lower layers of the atmosphere moisten up, but this snow could switch over to a period of wintry mix later on in the evening as the atmosphere warms up more (notice the warm "push" at 850 mb - 5000 ft on the left). Once we reach a certain threshold of warming on Monday night into the wee hours of Tuesday morning, all the snow, sleet, and freezing rain should transition to plain rain and the wintry weather headaches will be no more. Before everything switches over to rain an inch or so of snow could be on the ground around the I-40 corridor, including Jackson, according to the latest forecast models. Areas in Northwest Tennessee will switchover to rain a little later on than I-40, so there may be up to two inches on the ground. This is nowhere near set in stone yet and I'm willing to bet we'll see a few small changes in this forecast before the weekend is over.

The models agree that snow will fall across West Tennessee on Monday, but there are differences in when exactly this warm layer aloft will come in enough to switch the snow and wintry mix over to rain. The 18z NAM seems the most conservative on snow amounts at this point, with only a half inch in Jackson on Monday night. It also suggests that we might avoid a wintry mix and switch immediately over to rain. There's even a brief shot of rain just before the snow starts on that model. The GFS is bullish on snow amounts with over an inch in Jackson with the aforementioned wintry mix period (depicted as freezing rain on the BUFKIT output to the right) before the switchover to rain. The main issues seem are the timing of the warm air intrusion aloft and how strong it will be. So while this won't be a huge winter weather event by any stretch of the imagination, a few travel issues may crop up on Monday evening as the snow and wintry mix is falling.

1/12 - 6pm - Another Cold/Warm Roller Coaster

Cold air is filtering into West Tennessee and North Mississippi as a cold front that came through earlier this morning continues to move east. Snow showers fell as far south as portions of North Mississippi this afternoon, but the bigger snows from this system were confined further north into Missouri, Illinois, Kentucky, Indiana and the Great Lakes. Check out this picture below that my sister sent me of the scene this afternoon at my house in Louisville, KY: 


Even though only an inch or so will be on the ground by later tonight, the gusty winds of 20 mph+ could create blowing snow conditions with low visibility.

You'll feel the cold air behind the front tonight for sure if you're out and about. By early tomorrow morning temperatures across West Tennessee could be in the lower 20's and upper teens while North Mississippi will bottom out in the lower 20's. Highs tomorrow will range from the upper 30's in West Tennessee to the mid 40's further south in Mississippi.

That's about it for the cold though. Not long at all, right? Warmer weather will begin moving in for the weekend and early next week a ridge builds into the eastern half of the nation. Temperatures will likely get near 60 early next week before another system brings rain on Monday night and cooler temperatures for the middle of next week. The roller coaster continues!

12/10 - 2:30pm - A Cool Weekend Before the Rain

The sunshine and drier air moving in helped us get into the lower 40's this afternoon in Jackson. This is a welcome surprise since all indications this morning were pointing to a high only in the upper 30's. Tomorrow will be a day like today again in the 40's with plenty of sunshine. By the middle of next week we'll be talking warmer temperatures in the 50's and 60's, but rain chances will be on the increase. Thursday looks to be the best shot at rain in West Tennessee as a cold front generates a line of thunderstorms that will move though ahead of the front. Some of these could be on the strong side, so this is something we'll have to keep an eye on.

10/22 - 12:30pm - Warmer Temperatures in West TN, then Snow?

Jackson, TN bottomed out at 32 degrees this morning, which is two degrees warmer than our low temperature yesterday but still very chilly. We'll warm things up gradually around West Tennessee this weekend with 60's for highs today, 70's for both tomorrow and Monday, and 80's for Tuesday. What a warm-up! A cold front coming through on Wednesday night will generate some thunderstorms for Wednesday and Thursday, possibly into Friday as well. This system has slowed down on the computer models a little bit, but I think we should have all the rain out of here by Friday evening. It will be MUCH colder behind this front and as NWS Memphis points out, there's even a hint of some hypothetical snow on the computer models with this system:
IN FACT...LATEST MODEL GUIDANCE INDICATES AN UNSEASONABLY COLD UPPER LEVEL LOW MOVING
ALONG OR SOUTH OF THE INTERSTATE 40 CORRIDOR NEXT THURSDAY NIGHT INTO FRIDAY WITH 925 MB TEMPERATURES NEAR ZERO AND 1000-500MB THICKNESSES SUB 540 DAM. IF THIS WERE TO OCCUR...THEN IT WOULD BE POSSIBLE THAT SOME WET SNOW COULD MIX WITH THE RAIN IN SOME LOCATIONS THURSDAY NIGHT INTO EARLY FRIDAY MORNING. OBVIOUSLY THIS SYSTEM IS STILL SEVERAL DAYS AWAY AND THIS SCENARIO IS UNLIKELY CONSIDERING THAT WE ARE STILL IN LATE OCTOBER.
Honestly I don't think much if any snow will make it to the ground on Thursday night, but it could be close as some very cold air filters in behind that cold front. Check out some video from this morning's edition of Good Morning West Tennessee on WBBJ below:

10/15 - 3pm - It's Blast Furnace Time in West Tennessee!

Are you ready for a big warm-up? As high pressure shoves eastward we'll be seeing southerly winds bringing in some very warm air this weekend. This will push highs into the middle 80's for Sunday and Monday, which is almost record-breaking for West Tennessee. A cold front will bring an end to the warm temperatures on Monday night and storms appear likely. Some of these could be on the strong side, but we're not expecting a severe weather outbreak at this point. Temperatures behind this front may struggle to reach 60 on Wednesday, but we'll warm into the upper 60's by the end of the workweek. Check out my video below for a full forecast!

10/3 - 2:30pm - Gradual Warm-Up on the Way!

After having lows in the upper 30's this morning across much of North Mississippi and the Golden Triangle, we're enjoying temperatures in the lower 70's this afternoon. High pressure will gradually move east of us this week, meaning southerly warm winds will return to the region. Warmer temperatures are on tap throughout the week here in Starkville, getting into the mid 80's by the time we cap off the workweek on Friday. The next chance of rain will be sometime early next week, so enjoy this nice stretch of weather! Check out the video below for your detailed forecast:

1/16 - 10:30am - WBBJ Video

Quite a bit of variation in temperature will happen this week in West Tennessee with multiple cold fronts bringing in precipitation. Monday and Tuesday should be the big rain days this week, but there's also a chance on Thursday associated with one of the aforementioned cold fronts. Temperatures after the passage of this front on Friday and Saturday will dip into the 30's for highs, so be ready for some more cold weather! Check out the video below for more details:

12/14 - 12am - Cold is Here and Another Louisville Storm Looms

My apologies for posting so late today. I didn't expect the recovery time from my wisdom teeth removal procedure this morning to last so long, but I think I'm about 95% back to normal now. Cold temperatures are the big story tonight as clouds continue to clear out of the area and cooler air filters in from the northwest. Low temperatures will hover around 8 degrees early tomorrow morning and we're already well into the teens at the eleven o'clock hour here in Louisville. Check out some of the surface observations on the image to the right. Indianapolis and Evansville, IN are coming in at 9 degrees at the moment with temperatures getting even closer to 0 as you make your way toward Peoria, IL. Wind chill values will get a few degrees below zero tonight, especially in the suburbs of Jefferson and surrounding counties.

Our attention turns to yet another storm that should affect the Louisville area as soon as Wednesday evening. If you thought this past storm was a bear to forecast, try figuring this one out! Since temperatures will be hovering near freezing at the surface across the area with upper-air temperatures varying, this is going to be a real mess. The 0z NAM model run keeps Louisville and points northward mostly in the snow, but the 18z GFS had quite a mixed bag of precipitation for us, including freezing rain, sleet, snow, and plain rain. The 0z GFS is just now coming in and it appears that there will be a longer period of snow here in Louisville according to that run, but freezing rain or sleet could take hold on Thursday as warmer temperatures make their way in aloft (still need time for the BUFKIT output to be generated to find out exact precipitation type). If I had to guess right now, I'd say that Louisville and Southern Indiana will start out as snow on Wednesday night before switching over to either sleet or freezing rain sometime early Thursday before gradually changing back to snow as the storm ends. Should temperatures at the surface get just above freezing on Thursday, that period of freezing rain could turn to plain rain at times.

It's a real sticky situation as you can gather from my comments above. Since just a few miles will make a difference during this Wednesday/Thursday event, snow, sleet, and freezing rain amounts will vary wildly across Kentuckiana. I'll have an update tomorrow with more specifics and hopefully the computer models will have a better handle on this storm by then.

Check out some video that I shot of today's snow accumulations in Louisville below:

12/10 - 12:30pm - Crazy Weather on the Way in Louisville!

I'm back home in Louisville after a long drive from Mississippi last night. My third semester at MSU is over after going through my final exams and now it's time to move on to more important things, like a potential accumulating snow here in Louisville this weekend!


The Latest
The computer forecast models have had a very difficult time trying to forecast this weekend's storm across the Upper Midwest and Ohio Valley. Earlier this week there were vast differences in where the low pressure center of this storm would track. Some models had the low moving into central Tennessee or central Kentucky before cutting northward to Ohio/West Virginia, and others had it moving into Wisconsin, Illinois, and Indiana before cutting north to the Great Lakes. The Tennessee/Kentucky track is the one that would give Louisville a snowstorm, but it appears a more northerly track will take place. The HPC's (Hydrometeorological Prediction Center) depiction of the northern track is on the right image. Luckily, for you snowlovers out there, this is not the end of our snow chances for this storm here in Kentuckiana!

As the cold air behind this storm catches up with the back end of the rain we'll see on Saturday, we may see a brief burst of wet snow on Saturday night. Then, light snow will wrap around the back end of the storm and impact us from the north on Sunday, possibly into Monday. By the time this is all said and done, I think Louisville will have 2-3" (isolated 4") of snow on the ground with lower amounts south and higher amounts north of here. The 6z GFS model seems to be picking up on these totals well and I've posted its forecast snowfall accumulation map to the left. You can click the image for a larger view if needed.

Here's what the National Weather Service in Louisville says about all of this:
THE COLD FRONT LOOKS TO PUSH THROUGH THE AREA SATURDAY EVENING BEFORE MIDNIGHT OVER MOST LOCATIONS.  DEPENDING ON HOW FAST THE COLD AIR CAN CATCH UP TO THE PRECIP...THERE MAY BE A BRIEF CHANGE OVER TO SNOW ESPECIALLY IN THE BLUEGRASS BEFORE WE GET INTO A BRIEF DRY SLOT EARLY SUNDAY MORNING. WRAP AROUND LIGHT SNOW WILL THEN PUSH THROUGH THE AREA ON SUNDAY.  LAKE ENHANCED LIGHT SNOW WILL CONTINUE SUNDAY NIGHT THROUGH MONDAY BECOMING MORE CONFINED TO OUR SOUTHEAST INDIANA COUNTIES AND THE BLUEGRASS BY MONDAY AS MOISTURE SLOWLY PULLS AWAY FROM THE REGION.  TOTAL SNOW ACCUMS LOOK TO BE BETWEEN 1-3 INCHES FROM SAT NIGHT THROUGH MONDAY WITH THE HIGHEST ACCUMS EXPECTED OVER SOUTHEAST INDIANA AND THE BLUEGRASS REGION.

Even though we have a general track somewhat ironed out now, there are a couple of details that could increase our snow totals. While the GFS/ECMWF (European)/NAM/CMC models all generally agree on a northern track to this storm, the UKMET model is still taking a more southerly track near the Ohio Valley. At this point I think it's an outlier solution, but nevertheless there is a sliver of a chance that the low could take a little jog southward and impact our snow totals. There's also a chance that a secondary low could form well to the south of the primary storm and the implications of that are pretty substantial on our snow totals. Chances for that look slim as well as most computer models either don't have it or get rid of it before it exits Texas. Again, these are just a couple little things to watch that could affect us if they come to fruition by some outside chance.

As if the snow wasn't enough, we'll also have to contend with gusty winds of 25-35mph on Sunday which will blow the drier snow around and create visibility issues. Temperatures will also plummet during the storm as a cold front comes through, meaning we'll see highs only in the 20's for Sunday and Monday here in the Metro. Factor those chilly temperatures in with the winds and you've got yourself below zero windchills. That's dangerous weather in itself... stay warm out there!

I'll be posting updates on my Facebook and Twitter accounts today if there are any updates.

11/6 - 5:30pm - Chilly Morning in Jackson!

It was downright cold this morning in Jackson, TN as temperatures bottomed out at 24 degrees during our newscast. High pressure will keep skies clear and conditions dry for about the next week or so, but stormy changes are on the way as we head toward next weekend. Check out some of my weather clips from this morning's episode of Good Morning West Tennessee on ABC 7:

9/10 - 3:30pm - Here Comes a Cold Front! / WBBJ-TV

It may have been hot and muggy, but the weather for yesterday's MSU/Auburn game was perfect by most counts. It became clear very early in the day that the small chance of rain in the forecast for the game was gone, which was very good news considering the crazy rainfall we had on Wednesday that was on everybody's mind. Showers and storms have developed to our north this afternoon where a warm front is pulling eastward and we may see some of those develop down here in Starkville as the afternoon progresses. Rain chances will be higher tomorrow compared to today with the approach of a cold front that should pass through on Sunday. I think the best chance for rain tomorrow will happen in the late afternoon hours as the heating of the day coupled with the lift from the approaching front come together over North Mississippi. Temperatures next week should only hit around 90 degrees with lower 60's for lows due to the decreased humidity behind this cold front.

I'm off to Jackson, TN for the weekend to begin training and getting ready for my new job at WBBJ-TV ABC 7. It's exciting to be starting my first TV job soon and I should hopefully be on the air for some introductory broadcasts within the next few weeks. My Saturday morning shift officially starts on October 2nd and I'll try to post videos of my broadcasts on the blog if possible. Should be fun!
