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

[Fred Gossage]

It's going to take more than the sun coming out to destabilize northwest Alabama. The outflow with the morning round is still sinking south with time. That means it's going to be harder to recover dewpoints, despite the sun maybe coming out and temperatures with time getting back into the mid 70s. In addition to that, if winds do become more southerly over north Alabama, we're not advecting an unstable air mass northward. We are instead advecting from an area with rain-cooled air and overturned lapse rates. The threat isn't over for north Alabama to the north of these storms, but it's a whole lot lower than it otherwise would be, and I'm growing increasingly skeptical.

MS/LA however could get interesting later

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.

I'm at 79 temp in McCalla. Looks like it is upper 70s in the southern Birmingham suburbs and still low to mid 70s in Birmingham proper. But, yeah, hopefully this heavy rain will reduce the threat in the areas it is currently passing over. I guess my question would be if there are any breaks in precip that allows things to warm back up.

Edit: to Fred's point I think areas north of the precip definitely face a reduced threat now because they can't really advect in warm air from areas to the south getting inundated with rain.

Some more supercells have started firing around Jackson MS in front of the main line of storms.

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.

I'll kick in the extra server just to make sure we handle the bumps in load.

70/66 here, hopefully far enough in the rain cooled mass to keep things tame up here this evening. Had some tasks today but looking like there might not be enough breaks between the rounds to get much of it done haha

Additional servers are about to come online. Thanks to our sustaining members (those with the 2021 Supporter title) for helping us out during busy times.

The storms rolling through the ATL metro produced lightning that briefly knocked out power here and vaporized a few trees in my neighborhood.

I assume the reason SPC hasnt expanded MOD Risk further north relates to the ongoing convection in north & central AL.

At 1 pm a very large complex of severe storms moving E/NE through central La/Ark into Miss headed towards bama.
This will likely be the heart of the action & energy for later this afternoon/evening for Bham southward.

Things seem to be loading fine now. Thanks!

We had a crazy amount of rain in downtown Bham for the last hour, sounds like it’s finally letting up.

 

[Bama Ravens]

I’ve received 2.66” of rain so far where I am about 15 miles north of Birmingham.

We're having a CRAZY thunderstorm in Hoover, AL, right now. Near Moss Rock Preserve. It's quite hurricane-like.

TOR for Cleburne Co.

NWS has issued a Tornado Warning for Cleburne County until 2:00 PM

Cell East of Crystal Springs, MS looks to need a tor warning

Next scan not as impressive. Winds jumped to 90mph in previous scan

We've got our first severe thunderstorm watch of the year up here. Several tornado warnings yesterday without even being in a severe thunderstorm watch somehow.

Temperatures have dropped to the mid 60s in Madison, Alabama.
