That cell definitely looks stout on satellite: The setup is interesting to me since there seem to be 2 lines of more intense convection with one? MCS (colder cloud tops and radar are how I'm distinguishing that) that seem to merge over the OH river on the KY and IL border. I've seen this before with two distinct bows and a gap in the middle and always wondered what the cause for that was.

This sucker is hauling it. 1 - 2 hours ahead of HRRR. Always liked MCSs as long as they don't have a ton of wind. As MRX mentioned, HRRR has been more consistent with at least timing, while other models like NAM and RGEM have already lost it entirely. HRRR gives the northern limb a boost as it swings through KY and TN, will be interesting to see if, regardless of timing, this predicted aspect of it develops. Radar looks auspicious for that, as of now.

Satellite loop of today's storms:

This was all that was left of the rotation over Clinton in the radar loop above, when it moved over Knoxville, just north of my area (in a one minute time lapse): Radar loop at the same time:

The cell in Knox now has a warning too. Decent hook on radar and each of the three cells behind the Knox county one look like they may have a little hook on radar too:

Tornado warning in Hancock County and a couplet just north of Knoxville:

Not sure what is going on, but there is a cell that has just been dumping over Bledsoe county for a while: If radar estimates are correct that's 7 inches in around 3.5 hours.

We have a funeral compilation video: Probably one of many, lol

Saw some crazy pictures out of LaFollette from yesterday. Downloaded radar loop .gif of the event. It goes a little beyond the storm, but interesting to see that a little meso vortex? or something swirly develops over Campbell county and moves N afterwards.

Definitely brought them all together much better than anything I could have done!

Already over the humidity too! Learned a little about Grand Canyon North Rim's micro climates too. The whole Kaibab Plateau runs NW to SE and makes for some lovely orographic lift if there is a SW flow. I had some access to Tropical Tidbits and weathermodels and was watching the RGEM and Euro. Both suggested that a front would swing through and give a good burst of snow between 1 and 4 PM on May 19. So I told my hikers to try to be back by around 2 PM (some had started at 5 AM) and that we'd get maybe a heavy dusting and it would look scary for a bit and then it would be more convection/ hit and miss type stuff as the upper low/ cold pool swung through. I was 100% wrong, lol! Upper low spun to the north and kept that SW flow aimed perpendicular at the 8500 foot plateau. Ended up with 4 - 6 inches by the next AM. Amazing how little snow it takes to crush a tent (2 wet inches by 3 PM)! There were some people doing rim-to-rim-to-rim since it was opening weekend (not in my group) and maaannnnn, some of them were not prepared. Me and a friend went down into the canyon to make sure all the students made it back and saw some people (not ours) doing the hike in shorts and cotton t-shirts. They were soaked and cold. Some of them were somewhat delirious, but search and rescue was waiting at the top of the trail. Luckily everyone in my group was safe. Aramark did a good thing that evening too and had a free Prime Rib/ soup/ sandwich/ salad buffet for everyone at North Rim! My friend met a Canadian couple at the top of the trail who she let warm up in our van and they were so thankful that they gave two, $300.00 cabins to our students for the night. Image is me trying to salvage a tent.

Hi all, hope everyone is well!! Sooooo all that snow I kept wanting in winter, I got plenty on my camping trip to the southwest this year. Wasn't able to keep up with much of the Plains storm chasing folks, but I have to think that the big upper lows that kept rolling over my head in AZ, UT, and CO, must have been good for them. Also got to see the flooding of the Arkansas on the way back and maaaannnn, that looked awful. Can't say I'm unhappy to have missed all the heat here in TN Valley, but looks like at least the precip (but maybe not the interesting weather) has followed me back from the SW. Here are some pics of the snow and the skies: https://imgur.com/a/0Go5TdR Great group of students this year and some of the adverse weather seems to have made them closer than ever. It's amazing how little snow it takes to crush a tent, lol.

I'm sure some of you have heard about the recycling center fire in Knoxville. It's about 2.5 miles from my house and was watching it on radar yesterday. As I was watching it though I noticed an outflow boundary from an old storm intersecting it and that seemed to fire up a storm. Not sure if that is exactly what happened, but thought I'd share to see what y'all think: The storm I'm looking for fires over the NE sections on Knoxville, just north of downtown, at 23:20 time stamp. Just prior to that you can still see the smoke plume from the fire.
