...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Severe thunderstorms are not expected tonight.

...01z Update...

Surface front has surged into central TX, arcing across northern LA
into central MS early this evening. Isolated thunderstorms have
developed ahead of this boundary over east TX and across northern
IL. This activity should gradually increase in areal coverage as the
front advances toward the northwest Gulf Coast. 00z soundings from
SHV and LCH exhibit sufficient buoyancy for lighting within deep
convection, but profiles do not favor particularly robust
thunderstorms and severe is not anticipated.

Scattered-numerous thunderstorm clusters are currently noted across
the FL Straits within a seasonally high PW air mass characterized by
weak buoyancy. Early-evening water-vapor imagery depicts a notable
short-wave trough over the eastern Gulf Basin. This feature should
continue to support convection across the Straits and the southern
FL Peninsula tonight.
