Storms will once again be a possibility tomorrow but they shouldn't be as potent or widespread. We'll have the moist, warm air in place to fuel storms but there won't be any real trigger besides a small upper-level disturbance or two that could try to form and move through. Friday night will be the best chance for storms in the near future though as a cold front sweeps through West Tennessee and North Mississippi. Since these storms will move through earlier in the evening across West Tennessee there is the possibility of a few of these going severe. The chance for severe weather decreases as you move southward into North Mississippi thanks to the later timing during Friday night that they'll be moving through. Will the rain be out of the picture in time for the Mississippi State/Auburn game on Saturday at 11am here in Starkville? It looks like that may be the case at this point but it's too far out to know for certain since the front will be exiting the region sometime during the morning. The big story instead of the storms will be the much cooler, much drier air behind the cold front. We're talking about highs in the upper 70's this weekend in West Tennessee and highs in the lower 80's across North Mississippi, both with low humidity. What a change! We just have to get through a Thursday and Friday full of the deplorable heat and humidity we've seen lately before the wonderful weekend weather arrives.

9/5 - 11:35pm - Stormy Week, Cooler Weekend, and TV Tomorrow!
It's been a stormy day across West Tennessee and North Mississippi as a complex of storms moved through the region this evening generating multiple instances of severe wind. The storms that caused these are still moving southeastward through Northeast Mississippi but have lost their severe punch. Even though it appears these storms will miss Starkville and the Golden Triangle in Mississippi there is the possibility that an isolated storm or two will try to form off the western end of these tonight.

Looking for something to do tomorrow night? On the Travel Channel at 10 pm/9c tomorrow night a show called Extreme Tours will be airing and the first segment of the show will feature me and my pals at Storm Chasing Adventure Tours! A crew from the show came out to film and interview us as we chased this past spring in New Mexico and their footage along with clips from my library of tornado video will be airing. This program will showcase what we do as a tour group and how we make it happen. Quite a few of our tour guests and tour guides were interviewed for this and the camera crew that came rode along with us for a few hours. I did a sit-down interview with them along with an extensive round of showing off our vehicles and equipment. This should be a good show tomorrow and I'm certainly looking forward to my first appearance on a non-news national TV program! If you can't make it home in time to watch tomorrow be sure to set your DVR.

6/30 - 10pm - Wrapping Up the Storm Chasing Season
This storm chasing season is officially over for me as I'm back home in Louisville again. This week we went 2,930 miles through Colorado, Nebraska, South Dakota, North Dakota, Montana, and Wyoming. Our highlights of the week were a fantastic isolated severe storm with rotation near Lusk, Wyoming on Sunday and the tail-end of a line of storms that dropped a few funnel clouds near the Canadian border town of Scobey, Montana on Tuesday. All eight of us had a great time and I'm glad I was able to help forecast and explain to our guests what was happening with the weather during our chase.
The storm chasing we did this week brings my mileage for the season with Storm Chasing Adventure Tours to 11,313 miles. I've been from the Mexican border to the Canadian border this season and in the process I gained more perspective on just how huge the United States is. Over the next few weeks I'll be assembling a compilation of my best storm video from this season and I'll post it when I'm finished on here and on my website. All of my photos from the past four weeks of storm chasing are already up on my Flickr and Facebook albums, so click on over and flip through them!

6/29 - 10:15am CDT - The Chase Ends...
Today we're heading back to Denver as Tour 8 with Storm Chasing Adventure Tours ends. Right now we're making the seven hour journey from Valentine, Nebraska where we stayed last night. We had a storm about an hour south of Valentine yesterday that showed some promise, but it fell apart as it moved east. Tomorrow is when everyone departs and that's my cue to get on my plane back home to Louisville. It's been a great week with just about every day being a day with an active chase.
This is not one of those chase days unfortunately. With our required drive back to Denver we don't have time to chase any storms that are more than a few miles away from our route. There is a Slight Risk for storms today in Northeastern Nebraska stretching into South Dakota, but that's just too far out of the way for us. We may have a few run-of-the-mill storms along our route back to Colorado, but that's about it. I'll have a post tomorrow detailing our mileage and route from this week.

6/28 - 11:30am MDT - Waking Up in Nebraska
After storms in Northeast Colorado yesterday became contaminated by storms coming off the Front Range, we decided to head east to be ready for today's chase. After waking up in Ogallala, Nebraska this morning we're rested up for a relatively leisurely day without too much driving since we're already pretty much in our target area for the day. The Storm Prediction Center has a general thunderstorm risk out for Western Nebraska, Northeast Colorado, and Northwest Kansas today with a 5% severe wind risk.
The focus today will be a cold front that's slowly moving through the region today. Winds around this frontal boundary may shift out of the east a little bit and that's where we'll position ourselves since the best shear will be where that happens. Dew points will be in the 60's across Central Nebraska this afternoon with slightly lower readings to the west. These surface winds, while weak, and the moisture should be more than enough to get some storms going.
Winds aloft are a little less certain since they may change throughout the day. Early on this morning winds at 500 mb (18,000 feet) were almost westerly across the western half of Nebraska, but already we've seen a shift to the southwest. While not terribly strong, the winds up there could have just enough punch to get storms to become severe. Small embedded shortwaves within the flow may enhance these winds a bit in some areas too. By 6pm MDT tonight the RAP model (right) still has these winds out of the southwest aloft, so that's some good news. The thinking at this point is that the shear won't be high enough to keep storms from merging together and being clustered, but we'll see how that plays out.

6/26 - 10:40am MDT - Another Day, Another State
Yesterday near the Black Hills of South Dakota we saw a few storms develop but they never got organized enough to be good for chasing. One storm in particular had some promise but it just couldn't get strong enough to leave the elevation of the Black Hills where its updraft was rooted. Today we're going north from the Black Hills and moving into North Dakota where there should be a threat for severe storms this afternoon. In particular, areas near and just west of Williston, North Dakota into extreme Eastern Montana appear to be under the greatest threat since a few isolated storms could produce hail, wind, and maybe even an isolated tornado. The Storm Prediction Center only has a general thunderstorm risk for this area but there's a 2% tornado risk included. You'll see the Slight Risk up there in Montana as well in the map to the right, but that area is very remote and the surface winds likely won't cooperate as well for storms like they will in North Dakota.
Winds aloft are forecast to be stronger in our target area today than they were yesterday in South Dakota since the upper-level disturbance over the northwestern part of the country will be moving east a little. When you couple these stronger southwesterly winds aloft with southeasterly winds at the surface that can create some shear for rotating storms. It's worth noting that the best surface winds could be in Canada just north of North Dakota and Montana since an area of low pressure will be spinning winds around from the east there. Since we can't go to Canada, that's obviously out. Dew points in North Dakota are downright soupy this morning and will likely continue to be that way through the afternoon. Having 70 degree dew points right on the Canadian border is something you don't see too often.
With all the warm air and moisture in place, instability will be plentiful for storms. I talked about the threat of isolated tornadoes today on the SPC's outlook and that may very well verify if the instability and shear come together. A great way to combine those two factors is to look at the Energy Helicity Index, which starts getting higher in an isolated spot in Western North Dakota according to the RAP Model. We'll see if it's enough to get some good storms going this afternoon and evening!

6/25 - 10:30am MDT - Great Faces. Great Places.
Today's blog post title is the South Dakota's state slogan. As you can probably gather by that, we're in South Dakota today! Southwesterly flow aloft at 500 mb (18,000 feet) will be present in the western half of South Dakota, northwest Nebraska, and Eastern Wyoming today as the general pattern we dealt with yesterday continues. While the winds aren't terribly strong, the RAP model is beginning to pick up on an area of enhanced speeds near 30-40 knots around parts of Western South Dakota and Northwestern Nebraska. If this enhanced area verifies there could be some better storms under it.
At the surface right now there are southeasterly winds across this area, but the more easterly of the wind vectors are favoring Western South Dakota right now. We'll see how this develops throughout the day as surface conditions continue to change. We'll want these more easterly wind vectors becuase they'll contribute to low-level wind shear that could possibly lead to rotating storms, should they form.
I say "should they form" because we're still dealing with some very warm temperatures aloft. These warm temperatures aloft, called "the cap", inhibit storm development because rising air parcels can't continue to rise buoyantly if the environmental air around them is warmer than they are. The good news here is that temperatures at the surface today will again be in the 90's to near or above 100 degrees. This will really heat up these surface air parcels so that they might shoot through the cap. All models I've looked at this morning have the cap breaking at some point in the early to mid afternoon, but where exactly this happens is still in question. The 14z RAP model has an interesting hole in the cap at around 4pm near Rapid City, but our current thinking is that the Black Hills near Rapid City will be a focus for storm development because they are a constant source of lift and thus a typical location for storm initiation.
To get some of the heating we'll need for storms to form today, we need to have a plentiful supply of sunshine. Right now we do have a layer of clouds over South Dakota that is inhibiting this right now, but western parts of the state are clearing out and it should hopefully leave us with blue skies later this morning. Storms should form sometime after 3pm this afternoon should things come together as forecast. The main threats will be wind and hail from any storm that forms, but we'll be on the lookout for some rotation in these storms as well. The Storm Prediction Center has a general thunderstorm risk for our target area today, but also mentions a 5% severe wind and hail risk.

6/24 - 11:55pm MDT - An Unexpectedly Great Chase Today!
Looks like we may be heading north from Denver in the morning! A few storms may try to develop during the afternoon and evening tomorrow where South Dakota, Nebraska, and Wyoming meet.

Check out the video below to see the storm in action and then check out my Flickr or Facebook storm chasing albums for even more views of today's chase:
Tomorrow we'll be heading northward to the Dakotas or Wyoming. The Storm Prediction Center has a 5% risk for severe weather, but we'll be looking at all the data tomorrow morning to see how it all shapes up! Be sure to check back around noon tomorrow on the East Coast for a complete blog update with a discussion on where we're headed.

6/24 - 10:35am MDT - The Chase Begins!
This morning we're heading toward Cheyenne, Wyoming from Denver as we continue to look at weather data coming in. Today's setup still looks marginal by most accounts, but there are a few small features that could cause a few isolated storms to go severe. For one, surface winds out of the east in Wyoming, Northeast Colorado, and Nebraska will generate upslope flow, which is the lift mechanism we need to get storms going.
These winds will also create some shear because they will be interacting with southwesterly winds at 500 mb (18,000 feet). The issue with this is that the faster winds at this level will be further north toward Rapid City, South Dakota instead of where the more favorable surface winds will be just to the south. In any case, the wind direction at 500 mb will be good enough to usher in the wind shear and maybe some drying of the air at that level to increase instability.
When you put the expected helicity (caused by wind shear) and the instability together for today, you get the Energy Helicity Index (EHI). According to the 14z RAP model, the EHI may try to ramp up a little bit in Northeast Colorado and it even breaks out a little bit of precipitation just west of there too. Surface heating is going to be massive since temperatures will be in the 90's and 100's in some places, so we're hoping this also helps overcome some of the warm temperatures aloft (the cap) so that isolated storms can develop. We're grasping for small features today since there isn't any one thing jumping out to get our attention, but so far it looks like a storm or two could fire on the elevation near Cheyenne. We'll also be watching an area closer to Rapid City, SD to see how things develop up that way.

6/23 - 11:30pm MDT - Who's Ready to Go North?


The Storm Prediction Center has a general thunderstorm risk out for our target area tomorrow with no chance for severe weather. Since storms will be pretty isolated and in a fairly unpopulated area, it may not be worth it for them to issue any sort of severe risk with a setup this marginal. We'll see how things have developed overnight when we set out in the morning though. A secondary low may try to form in western South Dakota tomorrow according to the NAM and that may influence our decision on where to go if it forms since the best winds will be just to the north of the low center. Hopefully we'll see some storms!

6/22 - 10:30am - Storm Chasing: Part 2
Tomorrow morning I leave Louisville for Denver as I set out for one last week of chasing storms with Storm Chasing Adventure Tours this year. This will be a late-season chase, meaning that the threat for severe weather will be much further north than where it was during the peak of the season in May. Unfortunately it looks like the pattern will be a little dull until the middle part of next week due to a ridge of high pressure that will be in place over the middle part of the country. By Wednesday an upper-level low will finally move across Alberta and Saskatchewan, which will bring southwesterly wind flow and maybe even a secondary short-wave disturbance through the Dakotas, Wyoming, and even parts of Nebraska. Moisture looks a bit modest at this point, but it's way too far out to judge that properly since model accuracy is low this many days out.
During the chase next week I'll be posting daily blog updates here and real-time chase updates on my Twitter and Facebook accounts. Each morning I should be able to post a weather briefing as I did back in May so that you'll have the latest on where we'll be headed to and why. Hopefully we'll be able to find some good storms!

6/19 - 3:15pm - The Last Day of Spring
Tomorrow marks the first day of summer as the summer solstice occurs at 7:09pm EDT. The summer solstice put simply is the longest day of the year in the northern hemisphere because the north pole is tilted toward the sun. The sun will be directly overhead at 23.5 degrees north latitude or the Tropic of Cancer, located on a line that runs between Cuba and Florida. Meteorological summer, the three month period that meteorologists consider summertime in weather terms, started on June 1st with hurricane season.
I'll tell you that it's been pretty warm in Europe over the last couple of weeks. My family and I enjoyed a very nice trip around the Mediterranean Sea and traveled to Italy, Croatia, Turkey, Monaco, and Spain. I'm still a little jet-lagged from the marathon flight between Barcelona and Philadelphia we were on Sunday, but I'm slowly acclimating to Eastern Time again. Crazily enough, a tornado touched down in Venice, Italy last week well after we had left port on our ship. Thankfully there were no injuries, but some damage was done in a place that rarely sees tornadoes. Read more about what happened here.
The heat we had in Europe followed me home to Louisville (not meteorologically of course) and now we're experiencing quite a heat wave. High temperatures are expected to be at or above 90 degrees for most of the week here, but we may get a small break on Thursday night/Friday morning thanks to a cold front approaching the area. This thing may run out of steam just as it's nearing the Ohio River late on Thursday so rainfall chances could be slim with this.
If it continues to chug along further south than expcted we could have some storms around during this timeframe. Areas in Western Kentucky and Northwest Tennessee do need the rain, but unfortunately this won't be enough (if it happens at all) to assuage much of the drought in that region. The US Drought Monitor from the University of Nebraska-Lincoln has portions of this area under a moderate to severe drought.
In just four days I'll be heading to Denver to join Storm Chasing Adventure Tours for one more week of storm chasing this year. It's been a whirlwind of a summer break for me so far with three weeks of storm chasing and two weeks of travel in Europe under my belt, but I'm definitely excited for another week of chasing! It looks like storms may fire up early to mid next week in the Dakotas, Nebraska, and Wyoming as an upper-level disturbance inches onshore from the Pacific. It's a bit far out for specifics at this point, but I think moisture and upper-level support during this time might be decent if this disturbance comes onshore in time. The limiting factor may be capping (warm air) aloft since temperatures may be a little high up there. It'll be interesting to see how this develops over the course of the week!

6/1 - 9:15am - Going off the Grid
Starting this morning I will be on vacation for the next couple of weeks. I will likely not have internet access during this time so my blog and social media accounts will remain inactive until June 17th. As soon as I get back I'll be gearing up for another week of storm chasing that starts on June 23rd.
Here are a couple of weather tidbits going on today:
This is officially the first day of the Atlantic hurricane season. You wouldn't know it though because there have already been two named tropical storms Alberto and Beryl. No storms are going on in the Atlantic at this time and the forecast is for that to remain the same for at least the next couple of days.
There is a Slight Risk for severe weather over the Mid-Atlantic states today. A 10% tornado risk is in place from North Carolina to Maryland and there could be isolated supercell structures out that way during this afternoon's storms. A few high-based supercells may form in the Texas Panhandle this afternoon as well... hopefully my friends at Storm Chasing Adventure Tours can chase a few of these!

5/28 - 10:30am - Video from Friday's Chase
Check out this video taken on Friday just south of Hays, Kansas during our storm chase. The supercell storm we followed for a good portion of that day had quite a bit of blowing dust and even a few gustnadoes. I wish I could have captured more of the gustandoes, but they were happening very quickly and usually while we were driving. This cell ended up producing a very brief, very small string-like funnel before it dissipated.

5/26 - 11:35pm EDT - The Journey Home
Storms yesterday in Central Kansas did not produce a tornado for us. We did see a very brief string-like funnel at one point, but that was about the extent of our tornadic sights for the day. There were many tornadoes that touched down with damage reported closer sunset with these storms, but we had to make the judgement call to bug out and get back to Oklahoma City in time for people to get on their flights home before this happened. If these storms had organized a little quicker I think our chances of getting on a tornado would of been much better. The day began with a stop in Russell, Kansas where the Center for Severe Weather Research's ROTATE project happened to stop by for awhile. We were able to visit with them a bit and take some great pictures!
The chase began near La Crosse, Kansas where we followed a couple of developing supercells that had quite a bit of dust kicking out from under their ouflow. We followed a right-moving cell for quite some time, all the way to Bunker Hill, Kansas, as it cycled through weak and strong stages. This is the storm that produced the aforementioned string-like funnel cloud. Many a wall cloud came from this storm, but it was just too disorganized of a structure to get things going for a tornado. The storm that would form quite a few tornadoes (including an EF2-rated one near... you guessed it... La Crosse, Kansas) finally got its act together just to our southwest near sunset, but we had to bug out just as that was happening because we were so far away from Oklahoma City where we needed to be so that our tour guests could fly out. It's really too bad that we had to miss these tornadoes, but that's part of having to deal with the logistics of tour guests and the unpredictability of storm chasing. The storm structures were certainly spectacular though and we did see quite a few gustnadoes and dust being blow around. Video from these storms will be processed and uploaded tomorrow night when I get some time.
Yesterday and today have really been the same day for me. After we finished chasing in Central Kansas we had to make a bee line for Oklahoma City, where we made it in to town just after 3:30am this morning. My flight left at 7:35am this morning meaning I had to be at the airport around 6am, so I actually had no time to sleep in the interim. It's good to be back home in Louisville after being so tired! During these three weeks I've been with Storm Chasing Adventure Tours this month we've gone 8,383 miles across Oklahoma, Texas, New Mexico, Colorado, Nebraska, South Dakota, Iowa, Missouri, and Kansas. There are so many areas that we visited this season that I've never been to before, especially near the Mexican border in Laredo, Texas and Big Bend National Park. But I'm not done yet. After a few weeks at home and abroad, I'll be back out storm chasing again for a week starting on June 23rd and going through the 30th. This is typically a time where severe weather is found up north in the Dakotas and Nebraska, so I'll be flying out to Denver in about a month's time to meet up with everyone.

5/25 - 11:50am CDT - A Grand Finale
Ever since earlier this week we've had our eye on today's setup in Central Kansas. The moisture return, a low developing over Southwest Kansas, and upper-level wind support all kept us coming back to look at the models to see how it was shaping up. For a while it looked like the cap, or a layer of instability-inhibiting warm air aloft, was going to surpress storm formation but now we're seeing a situation where there will be just enough break in the cap to allow for a few isolated supercell storms to form. To get surface heating today to break that cap we need to clear out the clouds across Kansas first. A push of dry air at around 10,000 feet is currently moving from Southwest Kansas to the northeast and is eating these clouds for breakfast as you see in the satellite image to the right. We expect this to keep moving throughout the day and hopefully it will clear out the clouds in time to get some serious surface heating going.
The big story here today is the moisture return. For the first time this week we are seeing a situation where dew points will surge into the mid to upper 60's. Yes! This much-needed moisture will be the fuel for storms this afternoon and should give us a much better show than the moisture-deprived low-precipitation storms we've been seeing lately. While we don't have this moisture in the area quite yet, it's streaming in like crazy right now. Strong easterly and southeasterly winds are blowing this moisture into Kansas from Missouri and Oklahoma and will continue doing so throughout the day. Having mostly easterly winds in Kansas right now is a very good thing because this is creating just about optimal low-level shear for rotating supercell storms.
Speaking of wind shear, this will create quite a bit of helicity, or a corkscrew-like rotation of air in the atmosphere. When you combine helicity with instability in an equation you get the Energy Helicity Index (EHI). As I've said before I think that indicies and parameters can be distracting since human analysis is always better than a formula, but EHI seems to be fairly reliable since it is so basic and relies on two very basic ingredients. This afternoon's EHI values in Kansas will be the highest we've seen out here this season according to the Rapid Refresh model. That's some great news for storm chasers because higher EHI values typically correlate with enhanced tornado potential.
The Storm Prediction Center has a Slight Risk for severe storms today from Iowa to the Texas Panhandle and within that a 5% tornado risk in Kansas. This is quite the change from the previously non-severe "general thunderstorm" outlooks that they had been issuing for today because of the concern that strong capping may inhibit storm development. Today is our last chase day out here for Tour 3 and my last day out here until I come back for a week in June. If we could see some good storms today that'd be a great end to the first part of my trip! Tonight once we're finished chasing we'll be traveling back to Oklahoma City where I'll fly back to Louisville from tomorrow morning.

5/24 - 11:30am CDT - A Repositioning Day
Yep, there's a Moderate Risk for severe storms in parts of Wisconsin, Minnesota, and Iowa today according to the Storm Prediction Center. It's too bad because we simply can't chase there due to the amount of trees and vegetation along with a considerable distance from Oklahoma City where we need to be tomorrow night. Here's the plan then: We're going to drive south from Des Moines to Kansas City and then cut west in Kansas for this evening when we could see some overnight storms with lightning in that region.
Tomorrow still looks interesting to say the least. Right out front I need to say that this setup has a very high bust potential because of all the capping that will be in place. Warm temperatures of 10 degrees Celsius and higher at 10,000 feet (700 mb) will act as this capping mechanism because it will inhibit warm air from rising buoyantly into the layers above for thunderstorm formation. With that said, this cap may weaken just enough for a couple of storms to fire up in Kansas tomorrow. They would likely be very isolated due to the capped environment, so that's definitely a plus here.
We all know by now that the models have not been handling moisture very well lately and tomorrow probably won't be any different. The NAM model has dew points of 65 degrees Fahrenheit and higher in Central Kansas at 4pm CDT. If this is overdone and we see dew points between 60 and 65 degrees it still wouldn't be too bad. An area of low pressure smack dab over the middle of Kansas should help bring some of this moisture in and also create a considerable amount of wind shear for rotating storms, especially near the warm front just south of the Nebraska border. Again, this is all if the cap actually breaks tomorrow. If it doesn't we'll be sweating it out in the sun as we watch cumulus cloud towers fail to rise high enough for storms. Tomorrow morning I'll post again with an update on this potential.

5/24 - 12:35am CDT - We're in... Iowa?
We didn't think we'd be in Iowa tonight. The storms that formed yesterday (Wednesday) rushed eastward as the cold front in the region decided to push further east than expected. Unfortunately none of these storms really did much because they formed in a linear fashion and didn't have the moisture necessary to get too severe. One of the southern cells in the line just west of Omaha, Nebraska managed to be isolated for a while and generated a wall cloud that triggered a tornado warning. Our only option in this environment was to cross the Missouri River in Omaha and wait for the storms to come to us because it would not be good to have the storms outrun us while trying to find a way across the river. The storms slowed down and died out pretty much at that point so we threw in the towel for the day.
Tomorrow will likely be a travel day back to Kansas or Southern Nebraska as we await Friday's potential chase setup. Storms tomorrow will be up near the Great Lakes in Wisconsin and Michigan and we just don't chase there due to the distance from the Plains and lack of good chase environment up there. Strong capping should keep storms from going up in the central and southern Plains, but we'll keep an eye on that in case that changes. Friday's setup may be decent if capping aloft doesn't ruin it. A deepening trough out in California and hopefully some better moisture return from the Gulf of Mexico should create potential for severe weather. A strengthening low in Southeast Colorado/Southwest Kansas should provide ample surface wind support for rotating storms should this pan out as forecast. The Storm Prediction Center already has a 5% risk area for this in their 3-day severe weather outlook. I'm crossing my fingers that this setup will yield some good storms because Friday is my last day chasing in the Plains until late June!
