Areas affected...South-Central/Southeast Texas

Concerning...Severe Thunderstorm Watch 153...155...

Valid 210014Z - 210145Z

The severe weather threat for Severe Thunderstorm Watch 153, 155
continues.

SUMMARY...Severe threat will shift southeast this evening. New
Severe Thunderstorm Watch may be needed.

DISCUSSION...Frontal convection continues to grow upscale, extending
from west of Fredericksburg into central TX where an MCV may be
evolving over Limestone County. 1km inflow has increased ahead of
this activity over the upper TX Coast and there is increasing
confidence this evolving MCS will continue to forward propagate,
likely spreading toward/across the HGX CWA. Given the current
speed/movement, a new Severe Thunderstorm Watch will likely be
warranted across portions of the TX Coastal Plain/upper TX Coast.
