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.
