Yes, in addition to TORR warned cell, cell NE of Jackson seems to be exhibiting more supercellular characteristics

That supercell crossing the LA/MS border near I-55 to the south looks like a candidate in the next couple of hours. Forcing for ascent starting to catch up to these cells further south.

Mississippi, Alabama: Stay safe, y'all. There's no more beautiful place in the world than the South in springtime, nor more terrifying.

But I wonder, too: how did the Texas members do today? That state took some hard hits early on and I haven't read much news here from them yet. Probably too busy dealing with the mess..

Lawrence and Limestone Co. severe TS warning

 

[KoD]

New day 1 shifts enhanced risk east

 

[Equus]

Figured they might and makes total sense

 

[Richardjacks]

Given that we have a tor warned storm 2 counties away from the state line, this timing looks a little too slow to me.

Tornado warning out for cell Andrew was talking about

 

[Gail]

They pulled the hatched area also!

Definitely agree here... The timing is off pretty significantly

 

[The Colonel]

4 hour timeframe/window from NWS in AL and we are 4 hours from the event. That’s.....something.

SPC discussion:

Recent surface analysis places a convectively augmented cold front
extending from far southeast AR/northeast LA southwestward to far
southwest LA (near UXL). The fast eastward progression of the cold
front has lead to undercutting and resultant weakening of the
convective line ongoing across eastern LA. General expectation is
for this cold front to continue eastward, eventually interacting
with the lead convective line currently extending from central MS
southward through south-central MS. Interaction between these two
features will likely dictate the severe coverage overnight, with a
constructive interaction leading to an increase in severe
thunderstorms.

An additional factor favoring an increase in overall storm intensity
is the placement of the low-level jet. Recent DGX VAD sampled 60 kt
at 1 km and 80 kt at 3 km. This matches well with anticipated
strengthening of the low-level jet across eastern MS and western AL.

A favored corridor for this strengthening is along the warm front,
which currently extends from a surface low just northwest of HEZ
northeastward to just north of BHM.

The storm mode will likely remain linear, limiting the potential for
long-track tornadoes. However, strong low-level shear will still
result in the possibility of a few embedded, short-duration
tornadoes in addition to damaging wind gusts.

NWS Fort Worth confirms at least EF-3 damage with the tornado in Franklin (Robertson Co.) (that was the first storm of the day with the huge TDS)

 

[BayouWeatherGeek]

TWC is showing a school fire that was apparently started by lightning and it's bad.
