The latest runs of both the GFS and NAM have snow just to our south for tomorrow and late tomorrow night. The heaviest moisture is so very close, but a tight gradient exists as you go north:

This morning, the HPC had a SLIGHT risk of 4+ inches of snow in Central Kentucky and points east, but the newest outlook pulls the risk area further south into Tennessee and far South Kentucky. At this point I don't think anything is written in stone because of the amount of irregularity in the models. Even though the general track of the storm has been pretty consistent, a 25-50 mile shift north in the storm track will bring us more than just the snow showers the models are forecasting at the moment. This kind of shift is not rare 24-36 hours out, so I would not discount the fact that we could have an accumulating snow late Saturday.
We should top out at around 32 tomorrow for a high, with upper 30's for Sunday and Monday. 40's are back for Tuesday, with 50's for the remainder of the week.

As this cold front passes early tomorrow morning, cooler air will filter in behind it. Temperatures will start out in the 50's tomorrow, but will fall well into the 40's during the afternoon hours. This colder air coupled with a low passing to our southeast will fuel a snow chance here for Saturday. The 18z GFS runs has lowered snow amounts for the area compared to the 12z, and both runs have the bulk of the snow going just south of Louisville. No two models are in agreement with this system, so we could end up with nothing or a 1-3" snow accumulation if this moisture can move a hair northward in later model runs. More on this tomorrow!

These storms will be weakening as they come through during the early morning hours on Friday, so it's unlikely that we'll see any severe weather problems. A few snow showers are possible on Saturday evening as a low passes to our southeast, but little or no accumulation will occur. Highs in the 40's return for the weekend and the beginning of next week.

Rain chances will pick up tomorrow evening as an area of low pressure tracks up to the Great Lakes from the Plains. Storms will become likely late on Thursday with the approaching cold front to the south of the low. It looks like the storms will be strong, but it's still too early to tell if they will be severe. I think there is potential for some isolated severe weather, but an outbreak looks very unlikely because there is not much instability to work with.
The 12z GFS takes the low coming through the region on Saturday well to our south, suppressing most of the moisture down that way as well. After seeing some of the solutions yesterday, I'm not sold on that southern suppression and I think the low will track back north in successive model runs. This kind of setup has been happening all winter in the GFS, where a low is suddenly supressed southward for a few model runs and then quickly corrects northward in just one or two runs. The main thing is that we could see some precipitation on Saturday, but the track of this low and how much cold air comes south from the Great Lakes will determine whether it is rain or snow.
Monday, February 23, 2009
The weekend is uncertain at the moment. The GFS is being inconsistent with an area of low pressure coming through the region on Saturday. Its track will determine whether we see warmer temperatures and dry weather, cooler temperatures and rain, or even cold air with snow. If the low keeps the track on the 12z GFS and intensifies a bit more, we may have a bit of snow to deal with. It's too early to tell right now, so I'll have more information as the week progresses.

We could see a few flurries tonight as this system approaches, with a low just below freezing tomorrow morning. The rain should start around noon, but again, the snow will hold off until dinnertime. After a high of 30 on Sunday, temperatures will slowly rise to 50 by Wednesday. We should hold in the lower 50's for the balance of next week. Next chance of rain will happen on Wednesday, with heavy rain possible for Thursday.

Ryan Hoke is still in high school, but he knows just what he will be studying at Mississippi State University this fall: meteorology. He plans to use his degree, his love of weather, and his unruffled charm as a television weather broadcaster. The young weatherman is already a sort of institution in his hometown of Fisherville, Kentucky, where he keeps the public informed of local weather on his Ryan's Weather web site and in weekly videos he produces and posts to his web site. He has even been a guest weather broadcaster on WAVE TV 3. (A video of him on WAVE TV 3 is pretty impressive. It looks to us like he has been doing the weather in front of a camera for years!)
And he is not just a proud weather geek, he's a proud, entrepreneurial weather geek! Check out the store on his site where he sells such very cool things as tee-shirts that say, "I'm a Weather Geek. Are YOU?" (Altogether now: "Yesssss!!")
And what kind of station does the Boy Wonder use? Of course, it's a Vantage Pro2.
Ryan was featured in a story by Charlie White in the Courier-Journal. If you happen to run into Ryan, you might want to ask for his autograph now and beat the crowds.

Needless to say, I'm floored by this article and I think Davis does a great job with the newsletter.

Saturday afternoon - Low passes directly north of us and temperatures stay warm enough for all rain during the daytime.
Saturday evening - Clipper passes to our northeast and a cold front comes through. Temperatures drop below freezing and all rain changes to snow. A bit of moderate snow may come through, so accumulations of 2-3" are possible IF a good chunk of moisture comes from the southwest as the GFS advertises.
The 18z NAM has less moisture from the southwest to work with and hence less snow. Temperature profiles are similar though, so the time for changeover from rain to snow in the early evening looks pretty good at the moment. There's still some time for the models to change, but it's looking more and more like we'll see rain to snow with minor accumulations. We'll see if the models pull a fast one on the 0z runs and change things up.
In the meantime, expect temperatures near 40 tomorrow with sunny skies!
Wednesday, February 18, 2009
A few snow showers will come through tonight and tomorrow behind this sharp cold front, with temperatures only topping out at around 30. Looks like a high near 40 for Friday.
The newest NAM and GFS model runs have warmed up the storm coming through on Friday night into Saturday a bit, so we could get mostly rain instead of snow. We should know tomorrow what kind of precipitation we'll be getting, but I think we might be just cold enough for snow and that the models will correct back to a solution similar to yesterday's.
Tuesday, February 17, 2009
Enough about me, let's look at what the GFS run for a snow system on late Friday into Saturday:
The 18z is really layering on the precipitation as a low passes to our north. I don't like how this low is passing to our north and generating that much moisture south of it. Usually the low would need to go south of us if we were to have temperatures cold enough for it to snow and to have the bulk of the moisture. Temperatures warm just above freezing in the daytime during this event on the GFS, but it's still too far out to call that the correct solution. There's still quite a bit of time for the GFS to get its act together this week, but I think we'll get some snow out of this regardless. Could be an inch or it could be several inches as is depicted right now, we'll see.
In the meantime, showers will be coming through tonight and continue as heavier rain tomorrow with a high near 60. We'll see a brief changeover to snow early Thursday morning, and that should continue until the late morning hours. Flurries and snow showers with little or no accumulation are expected on Thursday with a high near 32. Yep, that's about a 30 degree temperature difference between the highs on Wednesday and Thursday... yikes!
We'll top out just under 40 on Friday and it's uncertain what exactly will transpire this weekend with this snow system. I do know that a bit of a warm up is in store for next week, so be ready for another ride on the temperature rollercoaster!

Video forecast will be updated tomorrow afternoon. Have a great Friday evening!

There are still 9,000 LG&E and 7,000 KU customers without power from yesterday's winds. Winds were much worse to our north and east, especially in Pittsburgh where upwards of 200,000 were out power.
In the short term, we'll see a high in the mid 50's tomorrow with rain coming in during the nighttime, which should be out of here by Saturday afternoon. Highs in the 40's will be around for the weekend. More 40's for next week.

We didn't get a terribly bad round of storms this afternoon, but areas to our south weren't so lucky. Our winds here tonight will be downright heavy as the pressure gradient tightens and the area of low pressure passes to our northeast. I wouldn't be surprised to see wind gusts of 70-80mph before 9pm tonight, then it should die down. As far as a comparison to the wind storm in September, it's not as bad as that storm right now. I'm worried that we could equal that storm though if winds from aloft mix down to the surface later this evening. Either way, we have numerous reports of wind damage and power flickering (if not out already) around the area. All I have to say is be prepared to be without power, because that could happen tonight for many.

We're under a 30% chance for severe weather tomorrow, which is at the high end of a SLIGHT Risk. We were under a 45% chance earlier today, but that they have since lowered that. A squall line (thin line of severe storms) will be coming through tomorrow afternoon sometime with high winds and the possibility of a few tornadoes. If the sun comes out tomorrow before this line comes through, expect a heightened level of severe weather.
The High Wind Warning will be from 7am until 10pm tomorrow. This has been put in place because we could see constant winds of 40mph with gusts to 60mph just before and after the squall line passes tomorrow afternoon. The squall line itself could generate wind gusts well over 70mph if it becomes severe enough. At any rate, winds should start to pick up tonight and last through the day tomorrow. As for power outages, I do think there will be some around the area. The number of power outages will depend on the wind speeds tomorrow.
One more day in the 60's tomorrow before we drop into the 50's for the rest of the week.

It was a lot of fun getting to do a real weather forecast on TV for the first time! I've never used a green screen to do the weather before, so it took some quick learning to get accustomed to it. I appreciate all of the e-mails and comments that I've been getting about the broadcast tonight!

The winner of our "Be a Weathercaster" contest....Ryan H., will be doing the weather on the 5:30 news tomorrow.
-John Belski's Blog
I hope that everyone can tune in at 5:30pm tomorrow for my first live weathercast!
At the moment, the SPC is thinking there will be a squall line (thin line of severe storms, usually packing high winds) east of the Mississippi River on Wednesday based on a front coming through with high dewpoints, indicative of a high level of moisture in the air. Instability will remain marginal at best according to the latest SREF, with the highest concentration remaining just to our west during this event. If we stay overcast the whole day on Wednesday, then instability will certainly be low. A sunnier day on Wednesday could spell trouble. A little bit of shear may come into play around here, but I think that will stay in the deep south. Overall, I think we'll see a fast-moving squall line come through here on Wednesday afternoon or evening, but it shouldn't be too bad. The main threat would be wind damage, but really nothing else because the line should be decreasing in intensity as it comes our way.
I know the clouds and showers weren't a great way to start the day, but temperatures will increase a couple more degrees this afternoon and it looks like we will see some sun. Tomorrow is shaping up to be even warmer than I thought, with highs around the area now expected to top out in the mid 60's! The warm air coming up from the Southeast should stick around for Tuesday and Wednesday, but that supply of warm air will get cut off as the cold front comes through on Wednesday night.
My next blog post will be late tomorrow evening... you'll want to check back for that one.

The GFS is showing a potent round of severe storms on Tuesday night heading through Texas and Oklahoma, but that should fall apart and die out before it reaches us. I'm a bit concerned about Wednesday evening because the GFS is showing quite a bit of heavy rain and possible severe weather at this time. It's too early to tell how severe it will be and if it will be in the immediate area, but it's certainly worth watching. I think the SPC (Storm Prediction Center) will have some areas outlined for severe potential on the Wednesday evening system in the coming days.
Here's the question that's been looming in my head for the last couple of days: "What happens when this ridge breaks down/moves out and colder air comes into play?" The answer is pretty simple according to the GFS; It's time to return to winter. More specifically, I think we'll have more chances for snow just after Valentine's day. Storms riding along the southern edge of the new trough that'll sink in should give somewhere in the region a good snowstorm or two at some point later this month. Pinpointing dates and places for these storms will start pretty soon, but more time is needed so the long range models can get their act together.
For now, I think we're pretty content with our current weather. Enjoy!

By the way, today is National Weatherperson's Day! To read more about how this tradition was started, click here.

In the long range, things look pretty interesting. The GFS is showing a couple storms coming through the region after the 13th with cold air to work with. It's way too far out to tell if any of these will give us snow, but the pattern is certainly worth watching.
Tuesday, February 3, 2009
Get ready for another cold day tomorrow as temperatures hold in the mid 20's and winds kick up to 15mph again. Thursday will top out just above freezing with more wind chill problems, but temperatures on Friday will ratchet up to around 50. We might even take a shot at that magical 60 degree mark next week, so stay tuned!

...WINTER WEATHER ADVISORY IN EFFECT FROM 4 AM EST /3 AM CST/ TO 7 PM EST /6 PM CST/ TUESDAY...
THE NATIONAL WEATHER SERVICE IN LOUISVILLE HAS ISSUED A WINTER WEATHER ADVISORY FOR SNOW...WHICH IS IN EFFECT FROM 4 AM EST /3 AM CST/ TO 7 PM EST /6 PM CST/ TUESDAY.
SNOW IS EXPECTED TO DEVELOP IN SOUTHERN INDIANA BEFORE DAWN TUESDAY AND SPREAD SOUTHEAST INTO NORTH CENTRAL AND EAST CENTRAL KENTUCKY EARLY TUESDAY MORNING. THE HEAVIEST SNOW AND HIGHEST ACCUMULATIONS ARE EXPECTED ACROSS THAT PART OF SOUTHERN INDIANA AND NORTH CENTRAL KENTUCKY NORTH AND NORTHEAST OF LOUISVILLE AND EXTENDING SOUTHEAST TO FRANKFORT...LEXINGTON AND WINCHESTER. ONE TO THREE INCH ACCUMULATIONS ARE EXPECTED IN THIS AREA.
LIGHTER AMOUNTS ARE EXPECTED FROM SOUTHWEST INDIANA THROUGH LOUISVILLE SOUTHEAST INTO EAST CENTRAL KENTUCKY...SOUTH OF LEXINGTON. THIS WOULD INCLUDE HARRODSBURG AND RICHMOND. ONE TO TWO INCHES ARE EXPECTED IN THIS AREA.
A WINTER WEATHER ADVISORY FOR SNOW MEANS THAT PERIODS OF SNOW WILL CAUSE TRAVEL DIFFICULTIES. BE PREPARED FOR SNOW COVERED ROADS AND LIMITED VISIBILITIES...AND USE CAUTION WHILE DRIVING.
So... The NWS puts a 1-3" estimate here, which seems good to me. I still think we'll get 2 inches in Louisville, but some areas just to our north could see 3.
I'm told these flakes were nearly two inches in diameter at times. This snow came from the system that veered off to our east in the computer models and is getting ready to hit the East Coast tomorrow.
Another place getting snow today is London, England. Just over four inches of snow sounds like a moderate snowfall for us, but for London this is the biggest snowstorm in 18 years! They usually don't have snow like that, so an army of brine and salt trucks just doesn't exist there. Heathrow Airport had to close a runway and an Airbus 330 from Cyprus slid off a taxiway. To read more, click here.
For us, snow will fall this evening and tomorrow. The NAM is being a little more liberal with precipitation amounts at the moment, suggesting somewhere between 1 to 3 inches for us with the cold temperature snow ratio accounted for. The GFS is suggesting just over an inch at the moment. I think we'll see two inches on the ground by tomorrow evening, but that should be it. There's not a lot of moisture to work with here, but temperatures in the 20's for tonight and tomorrow should help the snow fluff up and drive accumulations to the two-inch mark.
Today is Groundhog Day! Punxsutawney Phil saw his shadow this morning, so Winter will continue for six more weeks. Read more about the event here.
