   ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS PORTIONS OF THE
   FL PENINSULA...

   ...SUMMARY...
   Multiple rounds of strong to locally severe thunderstorms are
   possible across portions of the Florida Peninsula through tonight.

   ...FL...
   The initial round of strong to local severe potential is progressing
   offshore of the Space Coast. In the wake of this round, a
   substantial gap in convective activity is anticipated through the
   rest of the afternoon. Towards early evening, it is possible that
   convection over the northeast Gulf will attempt to develop
   east-northeast along the synoptic baroclinic zone across north FL.
   Given the stabilizing effects of the lead convection and remnant
   cloud coverage currently in its wake, appreciable destabilization
   across north FL is questionable. However, cloud breaks are evident
   and enough time should exist for weak surface-based buoyancy by late
   day. Thus, the extent of the cat 1/MRGL risk area has been
   readjusted northward given the presence of the front and adequate
   deep-layer shear. 

   A final round of strong gusts/brief tornado potential may develop
   late tonight across a portion of the southwest to west-central coast
   before spreading northeast across the central peninsula overnight.
   Most guidance suggest strengthening of lower-level (850-700 mb)
   moist advection will occur. This will likely be coincident atop the
   remnant outflow/leading baroclinic zone from this morning's
   convection.
