[html]MD 1276 CONCERNING SEVERE POTENTIAL...WATCH UNLIKELY FOR FLORIDA PENINSULA
Mesoscale Discussion 1276
NWS Storm Prediction Center Norman OK
0202 PM CDT Fri Jun 24 2022
Areas affected...Florida Peninsula
Concerning...Severe potential...Watch unlikely
Valid 241902Z - 242130Z
Probability of Watch Issuance...20 percent
SUMMARY...Widespread thunderstorm development is expected across the
Florida peninsula throughout the afternoon. Isolated damaging wind
gusts will be possible with collapsing thunderstorm cores. Weak
vertical wind shear will limit storm organization and preclude the
need for a severe thunderstorm watch.
DISCUSSION...Very moist and unstable conditions across the northern
two-thirds of the Florida peninsula has already resulted in the
development of strong thunderstorms along low-level convergence
boundaries. MLCAPE values in excess of 3500 J/kg and PW values over
2 inches (both exceeding 90th percentile values for 12Z JAX
soundings for this time of year) will support strong updraft
development. Water loading and steep low-level lapse rates will
support a threat of isolated wet microbursts. The weak flow/shear
throughout the troposphere will limit storm organization (primarily
pulse severe), so the damaging wind threat is expected to remain
isolated, precluding the need for a watch.
