Starting to see multiple areas of rotation in the line especially the northern half.

Couplet could be reorganizing on west side of Rainsville, AL

NOTE: I find it really interesting that we've had Cullman, Tuscaloosa, Birmingham, Rainsville, etc. all in tornado warnings today, and in most cases with confirmed tornadoes (not that the cities have all been directly impacted, but at least have been in the polygon). Then we had the trailing supercells traveling that corridor of Tuscaloosa-Jefferson counties. I also want to note that the first tornado in Mississippi, reminded me of the Philadelphia, MS tornado on 4/27, with it's tilted stovepipe shape from some angles (though obviously this tornado today was not nearly as violent). Could just be me about that last part, but today felt like a wannabe 4/27 in some ways lol. Some of the images of multi-vortex tornadoes breaking apart and reforming also remind me of the beginning stages of the Cullman tornado from 4/27 as well (again, I would say, less violent today than back then). Saw lots of pictures of wedges, even with a couple horizontal vortices, and yet a lot of other pictures of wispy brief 'naders as well. Today is not totally over, as we have kept hammering home, but it's still really fortunate that the high ceiling doesn't look like it will be totally met. The fact that we've had no reported fatalities up to this point seems like a miracle to me.

At this point I concede that the line is simply moving too fast. Obviously, anything can happen but it's moving into much more stable air and the LLJ never has been able to get synced up.

Looks like we'll just have to wait tomorrow it seems like for the next spark of severe weather

Well, would you look at that?

It appears that with the rapid progression of the squall line to the east, there's actually a window for pop-up thunderstorms on the back side of this system, and there does appear to be some mild convection firing. I don't think any of it comes anywhere close to severe, but it looks like the HRRR wasn't far off with that depiction, though it clearly has been a bit off over the squall line becoming a line of semi-discrete supercells.

The squall line remnants have weakened into a large mass of clouds and showers.

I’m wondering if this is going to be one of those cases where instead of a quick passage of precip and storms, it instead festers into the afternoon and minimizes the threat. Unless there’s more development expected behind it, the earlier arrival of storms means there will be less time for a good amount of sun and destabilization.

On the contrary, it’s actually weakened so much and is moving so fast, I’m now thinking it could clear out well before peak heating, allowing for sufficient destabilization for re-development later in the day.
