...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Thunderstorms will be possible this evening into tonight across the
western Gulf Coast states. Severe storms are not expected.

...DISCUSSION...
At mid-levels today, a trough will dig south-southeastward into the
Desert Southwest, as flow becomes west-southwesterly across much of
the southern U.S. In response, moisture advection will take place
across the western Gulf Coast states. By mid to late evening,
surface dewpoints are expected to reach the middle to upper 60s F
along parts of the Texas Coast. This will result in an increase in
instability supporting isolated to scattered thunderstorm
development. As warm advection continues into the overnight period,
a gradual increase in convective coverage should occur, mainly
offshore where instability and low-level flow are forecast to be
stronger. Due to this, some cell organization could occur just
offshore from the upper Texas Coast after midnight with a few
rotating storms possible. Over land, instability is forecast to
remain relatively weak, which is expected to limit the severe
potential through daybreak on Thursday.
