Severe WX Severe Weather Threat: May 2-5, 2021

[Julian]

I am becoming less concerned, convection mode is very messy, the chance of an organized cold pool forming is looking less likely...at least northwest of Bham.

The lightning has been insane in the walker county storm. I’m a little surprised the NWS never issued a severe T-Storm warning.

Nice signature on the Tuscaloosa/Fayette TOR.

Tuscaloosa storm looks like it was a transient spinup to me as that boundary moving ESE interacted with the storm.

I agree. Not sure it ever touched down. It was radar indicated - no ground confirmation - CC clear

Are we still expecting 2 waves today or what? I saw on Spann's blog where he said yesterday there would be another threat from 3 this afternoon until 10 tonight. Is that still on the table or are things arriving faster than expected?

So much rain and lightning here. Glad the warned storm is deciding to stay south lol

tuscaloosa storm has collapsed

 

[South AL Wx]

SPC has upgraded portions of central/southern MS and SW AL to a Moderate Risk:

45% hatched wind risk in that area:

 

[Equus]

Didn't expect that upgrade, but guess all they had to do was hatch the 45% they already had

 

[David in SW Blount]

So areas north of The Ham got a one-level downgrade. But we may float away instead.

 

[Equus]

No kidding, there are some 3-4" swaths showing up on storm total precip already

As far as I have heard the 3-10 pm wave is still expected.

Is anyone else having trouble getting TW to load? It is loading really slowly for me, but other sites seem fine. I’ve noticed this on two different internet connections today.

 

[Equus]

Just watching to see if that destructive line that's expected to sweep through the moderate can get cranking; hopefully this far north things can stay fairly stable

I’m hoping all of us in and north of this cluster of storms over north-central Alabama right now will be sparred anything too bad from the line this evening. My temperature and dew point have already fallen back into the mid-60s, so hopefully the energy over this part of the state is getting used up.

 

[AL_ham_op]

Driving from Cullman to Bham earlier the sun popped out briefly but now we're cloudy again. How is the instability looking for later on today?

 

[Equus]

Yeah I'm barely at 70 right now and really doesn't look like there's going to be much sun, unless we get some insane advection hopefully this means everything stays a bit south.
