...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS
SOUTH/SOUTHEAST TEXAS TO LOUISIANA...

...SUMMARY...
Isolated strong to severe thunderstorms are possible today and
tonight from south Texas into western Louisiana.

...South/Southeast Texas and Louisiana...
Prevalent cyclonic upper-level flow will exist ahead of the
low-latitude southern-stream trough that will further dig and
amplify over northwest Mexico. A relatively moist (mid 60s F surface
dewpoints) warm sector will persist across much of south/east Texas
into Louisiana, to the east/southeast of a front across Texas.

Periodic showers/thunderstorms and prevalent multi-layer cloud cover
will tend to hinder appreciable destabilization, but a few
near-surface-based storms may evolve this afternoon into this
evening. This convection could pose a risk for locally damaging
winds and/or a brief tornado coincident with moderately strong
low-level SRH. Some risk for gusty winds should eventually spread
into parts of western Louisiana, though severe potential will remain
relatively low through the end of the period.
