   ...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.
