NWS Storm Prediction Center Norman OK
0322 PM CDT Mon May 13 2024
Areas affected…southern Texas into far eastern Lousiana
Concerning…Severe Thunderstorm Watch 235…237…
Valid 132022Z – 132215Z
The severe weather threat for Severe Thunderstorm Watch 235, 237
continues.
SUMMARY…Severe threat continues for WW235 and WW237.
DISCUSSION…Storm mode across southern Texas has gradually
transitioned to become linear over the last hour, with two broken
line segments moving eastward. The more western line of convection
has had recent reports of gusts up to 52 mph and golf ball size
hail. The main threat with this more linear convection will remain
damaging wind and large hail, with potential for a tornado or two
through the evening.
More discrete supercells have developed across the south Texas Brush
Country. This is moving eastward into an unstable airmass where
MLCAPE around 3000-4000 J/kg overlaps deep layer shear around 50
kts. This more discrete supercell activity will have the potential
to produce very large hail up to 1-3.5 inches.
