...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS
OF SOUTHERN LOUISIANA...MISSISSIPPI...ALABAMA...GEORGIA...AND
NORTHERN FLORIDA...
...SUMMARY...
Isolated strong to severe thunderstorms are possible through Tuesday
afternoon across portions of the central Gulf coast into southern
Georgia and northern Florida. Strong gusts and hail will be the main
hazards with these storms.
...Central Gulf Coast/Southeast Vicinity...
An upper shortwave trough oriented from the Mid-MS Valley to the
Ozark Plateau vicinity will shift east through the period, moving
offshore the Mid-Atlantic/Carolinas coast by early Wednesday. This
will result in modest height falls/cooling aloft over portions of
the central Gulf Coast/Southeast. Moderately strong deep-layer
west/southwesterly flow will persist across the southern states.
At the surface, a cold front is forecast to extend for the SC coast
west/southwest through southern GA/AL/MS/LA to near the TX
coast/south TX vicinity. A seasonally moist airmass will be in place
ahead of the front and thunderstorms are likely to be ongoing
Tuesday morning along the front. Most guidance is in good agreement
with the location of the front and ongoing convection, which should
quickly shift offshore from southeast LA/far southern MS/AL by late
morning to midday. However, the 00z HRRR is a bit faster, depicting
an MCS just offshore over the north-central Gulf, with storms mainly
impacting parts of southern GA/northern FL. Depending on the
location of the front and ongoing morning convection, at least some
risk for locally damaging gusts and hail will persist over the
central Gulf coast/southern GA/northern FL into Tuesday afternoon.
