Severe WX Severe Threat 25 March 2021

[Kory]

Broad rotation on those two supercells in Pickens and Sumter.

 

[warneagle]

CIN is already building in behind the showers in central MS and mid-level lapse rates are 8-9 across most of LA and southwestern MS.

Very strong wording in the latest SPC D1 Outlook!:

"THIS IS AN UNCOMMON, UPPER-ECHELON PARAMETER SPACE. IN SUCH AN
ENVIRONMENT, ANY RELATIVELY DISCRETE SUPERCELLS WILL BE CAPABLE OF
MULTIPLE TORNADOES, SOME LONG-TRACKED AND STRONG TO VIOLENT (EF2-5
POSSIBLE), WITH CONSIDERABLE DESTRUCTIVE POTENTIAL. A VERY MOIST
BOUNDARY LAYER ALSO WILL REDUCE POTENTIAL COLD-POOL/OUTFLOW STRENGTH
VIA LESS SUBCLOUD EVAPORATION, SO THAT EVEN CLOSELY SPACED STORMS
MAY HAVE SUBSTANTIAL TORNADO THREATS. FORECAST WIND FIELDS AND
MODEL SOUNDINGS REASONABLY SUGGEST ANY SUSTAINED SUPERCELLS AND
THEIR TORNADOES WILL BE FAST-MOVING (45-55 KT), WITH INDIVIDUAL
TORNADO PATHS NEARLY AS LONG IN MILES AS THEIR DURATION IN MINUTES."

One of the most strongly worded SPC discussions I have ever read for sure.

 

[warneagle]

These thermos in the south in late March is...impressive.

 

[Tanner]

One of the most strongly worded SPC discussions I have ever read for sure.

That's what I am saying. I haven't seen wording like this since, you know...

 

[Equus]

Cool perspective on the current round of storms at sunrise...

I have NEVER read a wording like that. This feels like when I was living in Memphis. During the Super Tuesday outbreak, I heard Dave Brown say "folks, I've just been handed a Tornado Emergency for Shelby County." The first time he said he ever said that.

I think this is a very important statement.

Edwards is one of the best.

It's probably the most important. That boundary layer will set the table.

I'm gonna go throw up now.

 

[Argus]

We had moderate rain at 8:17, and now we have peeks of sun.

[TornadoFan]

This is gonna be a long day.

[Smokedevil]

Lovely. I work in ems, and I'm at work now, in the bullseye in northeast ms.

 

[NorthGaWeather]

SVR for Cullman/Morgan counties.

 

[Weatherphreak]

Already have two pretty mean storms in Central Alabama. Wouldn't be surprising to see something happen with one of those.

 

[warneagle]

Not sure I've seen the SPC explicitly reference the potential for EF5 tornadoes in an outlook before. Yikes.
