MD 0622 CONCERNING SEVERE POTENTIAL…WATCH LIKELY FOR FLORIDA PENINSULA
Mesoscale Discussion 0622
NWS Storm Prediction Center Norman OK
1214 PM CDT Wed Apr 26 2023
Areas affected...Florida Peninsula
Concerning...Severe potential...Watch likely
Valid 261714Z - 261915Z
Probability of Watch Issuance...80 percent
SUMMARY...A threat for large to very large (2-3 in.) hail and
damaging winds will exist this afternoon. A watch will likely be
needed within the next 1-2 hours.
DISCUSSION...Cumulus development/deepening is occurring along the
Atlantic sea breeze front in east-central Florida. Initial attempts
at storm development have not become sustained. Without much in the
way upper-level support, it may take another 2 or so hours of
heating before storms are able to mature. The 15Z Cape Kennedy
sounding showed mid-level lapse rates around 7.5 C/km. With
effective shear of 40-50 knots across the Peninsula, supercells are
the expected storm mode this afternoon and evening. Observational
trends support several model solutions of storms developing first
near the eastern coast before developing later in western/central
portions of the Peninsula. The improved shear and colder
temperatures aloft as compared to the last two days will support a
threat for potentially very large (2-3 in.) hail as well as
strong/damaging downburst winds. A watch for much of the Peninsula
is likely.
