....NO SEVERE THUNDERSTORM AREAS FORECAST...

....SUMMARY...
Severe thunderstorm potential appears low on Monday.

....Central Gulf Coast Vicinity...

A couple of upper shortwave troughs will migrate across the northern
Plains and Great Lakes vicinity on Monday. Further south, a broad
area of moderate deep-layer southwesterly flow will persist across
parts of the southern Plains to the central and eastern U.S. At the
surface, a weak low will be located over the Lower OH Valley with a
cold front extending from western KY/TN into central TX. This
boundary will sag south/southeast across TX/LA/MS/AL, while the
eastward extent of the front shifts east across northern GA and
portions of SC/NC.

Deep-layer southwesterly flow and warm advection atop this boundary
will result in continued thunderstorm and heavy rain chances for
portions of the South. Pockets of modest destabilization are
forecast (generally up to 1000 J/kg) with enough 0-6 km shear
available for semi-organized clusters. However, multiple rounds of
thunderstorms and widespread rain and cloud cover are contributing
to quite a bit of uncertainty regarding severe potential. Some
marginally severe thunderstorms could be possible if enough heating
can occur, but the overall threat appears too limited/conditional at
this time to introduce probabilities.
