...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS THE

FLORIDA PENINSULA...



...SUMMARY...

Strong thunderstorms, capable of marginally severe wind gusts and

hail, will be possible across the Florida Peninsula on Monday.



...Florida Peninsula...

An upper-level trough will move eastward to the Atlantic Seaboard on

Monday, as a cold front advances southward across the Florida

Peninsula. The airmass south of the front, in central and south

Florida, will have surface dewpoints in the 60s F. Surface heating

and low-level convergence in the vicinity of the front will result 

in thunderstorm development during the afternoon. Forecast soundings

at 21Z on Monday near the front in south-central Florida have MLCAPE

near 1500 J/kg, moderate deep-layer shear, 0-3 km lapse rates around

7 C/km, and steep lapse rates in the 700 to 500 mb layer. This

should support a marginal severe threat, with the primary hazards

isolated damaging wind gusts and hail. The threat will likely be

greatest in the mid to late afternoon.
