...NO SEVERE THUNDERSTORM AREAS FORECAST...
A few thunderstorms may develop across portions of the central Gulf
States late Wednesday afternoon and early evening.
...Central Gulf States...
Elongated, positive-tilted short-wave trough will progress across
the middle of the country during the day2 period as the primary
associated speed max ejects into the OH Valley. Along the southern
fringe of this system weak height falls will spread across the Gulf
States enhancing ascent along the trailing cold front. Modified
Gulf air mass will advance inland ahead of the front across the
lower MS Valley and this moisture increase could lead to a few
hundred J/kg of MUCAPE prior to frontal passage. Forecast soundings
suggest near-surface based parcels could be forced to their LFC
within the frontal zone and deepest convective updrafts could
produce a few lightning strikes between 21-03z.
