...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
Isolated to scattered thunderstorms are expected over parts of the
Southeast and Florida Peninsula today. Organized severe
thunderstorms appear unlikely.
...Southeast...
Recent surface analysis shows a cold front continuing to advance
southward this morning across southern LA/MS/AL into the FL
Panhandle and southern GA. This front will decelerate and stall
across the northern FL Peninsula today as a mid-level shortwave
trough moves eastward across the remainder of the Southeast. While
diurnal heating of a moist low-level airmass will occur ahead of the
front, relatively modest lapse rates should hinder the development
of any more than weak instability. Furthermore, low-level
convergence along the front is expected to remain limited. Even so,
isolated to scattered thunderstorms should eventually develop this
afternoon, focused across parts of the northern/central FL Peninsula
along and south of the front. While a stronger thunderstorm or two
with gusty winds may occur, the weak instability, modest lapse rates
aloft, and marginal deep-layer shear all suggest that the risk for
organized severe thunderstorms should remain low today.
