Somewhat conditional threat, but worth taking notice of.

SPC discussion regarding today (Sunday):
Day 1 Convective Outlook
NWS Storm Prediction Center Norman OK
0716 AM CST Sun Feb 11 2024
Valid 111300Z - 121200Z
...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS THE GULF
COAST REGION FROM EAST TEXAS TO ALABAMA...
...SUMMARY...
Severe thunderstorms are expected from east/southeast Texas to
portions of the Lower Mississippi Valley and middle Gulf States
today and tonight. Large hail, damaging wind gusts, and a few
tornadoes are all possible.
...Gulf States including East Texas to Alabama/Georgia...
A positively tilted upper trough over the southern Rockies will
eject eastward and increasingly take on a neutral tilt tonight as
cyclonically curved westerlies related to the polar jet strengthen
into the ArkLaTex/Lower Mississippi Valley through Monday morning.
Scattered elevated convection has been persistent along and north of
a west/southwest to east/northeast-oriented boundary since last
evening, with ongoing thunderstorms, some of which have been severe,
moving across northeast Texas early this morning. Some of these
storms may continue to pose a severe-weather risk this morning into
northern Louisiana/far southern Arkansas and possibly toward the
ArkLaMiss, in the form of large hail and possibly locally damaging
winds.
Farther south, although guidance varies regarding the extent of
storms within the warm sector later today, a semi-focused corridor
for deep convective potential into mid/late afternoon will exist
across east Texas into western/northern Louisiana, roughly bounded
north/south by the I-20/I-10 corridors. This will be along a
modestly deepening/northeastward-developing surface wave and the
preceding boundary shifting northward as a warm front. Moderate
buoyancy (1500-2000 J/kg MLCAPE) with minimal convective inhibition
will be prevalent by mid-afternoon along/south of the warm front,
with long hodographs (straight atop the boundary layer) and 50+ kt
effective shear and 150-225 effective SRH. Where warm-sector storms
do develop and mature (higher probability closer to the surface
low/warm front), supercells should be expected, with the potential
for very large hail along with a tornado risk, potentially including
a strong tornado.
Influenced by large scale mass response related to the evolving
upstream upper trough, warm-sector surface-based storms could become
more probable into this evening in vicinity of the advancing surface
low and northward-shifting warm front, within a corridor including
portions of Louisiana/Mississippi into Alabama. This would include
potential for a few tornadoes, damaging winds, and some hail via a
mixed mode of storms including supercells.

Has been torrential in NETx. Shreveport and the LA I20 corridor, you're on deck. It's comin'

Already several tornado warnings north of Houston:

RadarScope is showing Hammond radar online. Not sure if it’s working though

Woke up to hail in CS this morning. Now the sun is out.

The RadarScope folks went ahead and put it on there, but the radar not transmitting any data yet. Should be running in the next couple of weeks, though.

It hailed a lot this morning where I live. I never saw so much of it on the ground before

Not dangerous but snow. The temps are within a degree to get rain and/or snow. Some have said up to 15” if temps are just right but most likely in the 4” range. (OKC). They still don’t really know due to temp closeness.
This is from local channel 4 main meteorologist:

That forecast is one that will make some mets abandon social media for a few days.

SPC added an enhanced risk for today from parts of eastern Texas, through much of the northern half of Louisiana and much of central Mississippi.

Nasty looking storm heading my way in Inverness

Nasty line of storms moving across central Mississippi right now. They are currently below severe limits, though.

Stay safe out there.

Let's see if those storms along the front from Laurel up through Montgomery get going or more develop into the evening.
To use one of Duke's favorite lines: Never trust a warm front.

Keep an eye on that cell south of Vicksburg
