   Mesoscale Discussion 1161
   NWS Storm Prediction Center Norman OK
   1104 AM CDT Tue Jun 27 2017

   Areas affected...Portions of the Florida Peninsula

   Concerning...Severe potential...Watch unlikely 

   Valid 271604Z - 271730Z

   Probability of Watch Issuance...5 percent

   SUMMARY...Thunderstorms will continue to develop/increase in
   coverage through the afternoon. Isolated damaging winds may occur
   with the strongest thunderstorms. Due to expected limited coverage,
   a watch is currently not anticipated.

   DISCUSSION...Thunderstorms will continue to develop this afternoon
   within a moist, tropical environment across the Florida Peninsula
   this afternoon. The overall large-scale environment will be
   characterized by most-unstable CAPE values on the order of 2500-3500
   J/kg and deep-layer shear values below 20 kt. This weak deep-layer
   shear should preclude widespread thunderstorm organization, despite
   the overall degree of instability.

   Despite the lack of overall thunderstorm organization, there will be
   potential for isolated, wet microbursts given precipitable water
   values on the order of 2 inches.
