Severe WX Severe Weather Threat April 23-24, 2021

[Clancy]

Sun's out in the west ATL metro. Not much in the way of clouds out to my west either.

 

[us89]

I'm thinking the afternoon/evening threat for northeast AL/northern GA might be a little higher than the forecast thinking earlier today. The 12z NAM3k showed a very strong wedge extending all the way into central AL that didn't budge at all, while the HRRR has been more aggressive with advancing the warm front northward. The HRRR seems to have a better handle on temperature trends , as heating has been pretty good so far even under the clouds (as I type this it's almost 10 degrees warmer at KATL than the NAM3k had) and a substantial region of clearing is rapidly advancing into GA which will almost certainly destabilize the airmass.

Both models have consistently indicated development of storms over AL and west GA late this afternoon, likely reaching the Atlanta metro by the 8 PM EDT timeframe. Difference is that we'll probably have more instability to work with than we maybe thought this morning.

4/24 3pm CST Tornado Warning for Central/South Alabama

...A TORNADO WARNING REMAINS IN EFFECT UNTIL 330 PM CDT FOR EAST
CENTRAL CONECUH COUNTY...

At 300 PM CDT, a severe thunderstorm capable of producing a tornado
was located over I65 And US 84, or 4 miles west of Evergreen, moving
east at 50 mph.

HAZARD...Tornado and tennis ball size hail.

SOURCE...Radar indicated rotation.

 

[bwalk]

Rotation appears to be weak and diffused on the Alabama Conecuh Co tornado warning per my GRL3. More of a hail threat atm.

OK 3 pm SPC adds E-Cen AL back to slight but watch still well sough of us. BMX has Bham marginal.

 

[Clancy]

Lots of little cells forming in AL into W GA.

 

[bwalk]

Tornado warned cell 3:30 pm CDT Clarke Co (SW Alabama). Weak rotation but hail is a factor. Vertically Integrated Liquid is off the chart at 80+ KG/M2 (indicative of tall updraft reaching into the colder air & thus producing hail).

 

[Weatherphreak]

Got a couple of SVR storms sneaking up on North Alabama. Was beautiful for a large portion of the day. Glad to see Dega dodge the weather so far.

 

[Equus]

Pea sized hail here with severe warned storm earlier.

 

[brianc33710]

Yeah BMX just issued warning for SW Blount & NE Jefferson Cos. That includes me.

A surprise in Guntersville, AL we had been taken out of the slight risk so we weren’t expecting this. We were outside doing yard work when they put us back in the slight risk and added the severe thunderstorm watch. Hopefully the truck doesn’t have too much damage.

Nasty line of SVR-warned storms heading into the W ATL Metro.

 

[andyhb]

Posted my chase account on Stormtrack from what was an incredible show near Vernon and Lockett TX yesterday featuring multiple photogenic tornadoes.

2021-04-23 REPORTS: AR/LA/MS/OK/TX

Brittany and I have lived in the Athens area for fifteen years. We have never seen it get so dark so early before sunset in the middle of Athens. That's what she described to me while she was out this afternoon.

Possible TDS with this one, although not included in the warning yet:

This storm had a major couplet and TDS WSW of Tifton, as well.
