   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Severe thunderstorms are not forecast today or tonight.

   ...Synopsis...
   A southern-stream trough will continue eastward from the Southwest
   Deserts/far northwest Mexico early today toward the southern Plains
   by tonight. This system will include a strong, cyclonically curved
   mid-level speed max that will nose into western Texas during the
   late afternoon and evening, resulting in steepening lapse rates.
   Sporadic weak thunderstorms are expected today across parts of New
   Mexico into west/northwest Texas.

   ...East/Southeast Texas...
   Air mass modification over the western Gulf of Mexico will lead to
   steady low-level moistening for coastal areas late tonight into
   early Friday, with thunderstorm potential increasing. The primary
   warm sector and evolving surface wave should remain focused just off
   the Texas coast late tonight, although it is conceivable that a few
   strong near-surface-based storms/weak supercells could occur just
   offshore/near the middle Texas coast, with thunderstorms otherwise
   progressively more elevated and generally weaker inland (northward)
   across the remainder of east/southeast Texas. Severe probabilities
   do not currently appear warranted given expectations that a stable
   surface layer will likely persist over inland areas, but this
   scenario will be monitored and reevaluated in subsequent outlooks.
