Mesoscale Discussion 2277
NWS Storm Prediction Center Norman OK
0709 PM CST Tue Dec 24 2024

Areas affected...Portions of central and east/southeast Texas

Concerning...Severe Thunderstorm Watch 712...

Valid 250109Z - 250245Z

The severe weather threat for Severe Thunderstorm Watch 712
continues.

SUMMARY...Risk for large hail and damaging gusts continues across
Severe Thunderstorm Watch 712.

DISCUSSION...Thunderstorms are increasing in intensity and coverage
along a northeast/southwest-oriented pre-frontal confluence zone
draped across central and east/southeast TX this evening. A cold
front is also approaching from the northwest, and is beginning to
catch up to the northern portion of the confluence zone. Here,
congealing outflow is favoring localized upscale growth, and
damaging winds will be the primary concern. The one exception is a
persistent semi-discrete supercell ahead of the line which will pose
a risk of large hail (generally up to 1.5 inches) in the near term.

Farther south, regional VWP data indicates 30-40 kt of
west-southwesterly 0-6 km shear, oriented oblique to the pre-frontal
confluence zone. Given this shear orientation and increased
separation from the approaching cold front, discrete/semi-discrete
supercells will pose a risk of large hail (some up to 1.75 inches),
with damaging winds also possible.

With time, increasing storm development will favor upscale growth,
and the severe-wind risk will beco*e the main threat before
convection gets undercut by the front.
