   Areas affected...portions of the central Florida Peninsula

   Concerning...Severe potential...Watch unlikely 

   Valid 271946Z - 272215Z

   Probability of Watch Issuance...5 percent

   SUMMARY...A couple of strong and damaging wind gusts may occur with
   the stronger storms this afternoon.

   DISCUSSION...An MCS is approaching the FL Peninsula while remaining
   organized. Robust insolation is taking place ahead of the MCS over
   the central FL Peninsula, with thunderstorm initiation noted. Here,
   near 90 F temperatures amid 70+ F dewpoints, beneath modest
   mid-level lapse rates, is boosting MLCAPE to 2500+ J/kg (per 19Z
   mesoanalysis). Furthermore, appreciably strong mid to upper
   west-southwesterly flow is contributing to elongated hodographs and
   associated speed shear, as shown via RAP forecast soundings.
   However, the modest mid-level lapse rates are constraining buoyancy
   to relatively narrow profiles. This may limit the severe threat to a
   degree, either with the approaching MCS or any multicellular and/or
   transient supercellular storms that can mature ahead of it. The
   current thinking is that the more mature storms, or stronger cores
   within the approaching MCS, may support a couple of strong, damaging
   wind gusts over the next few hours. An instance or two of hail
   cannot be ruled out.
