Mesoscale Discussion 0395
NWS Storm Prediction Center Norman OK
0257 PM CDT Mon Apr 04 2022
Areas affected...portions of the southern Florida Peninsula
Concerning...Severe potential...Watch unlikely
Valid 041957Z - 042130Z
Probability of Watch Issuance...5 percent
SUMMARY...A couple instances of large hail or damaging gusts remain
possible with the stronger storms through the remainder of the
afternoon. Storms are near their peak in coverage and intensity,
with gradual weakening expected by sunset.
DISCUSSION...Transient multicellular thunderstorm clusters continue
to develop along sea-breeze boundaries and along the leading edges
of cold pools originating from the outflows of earlier storms. While
a few sub-severe hail reports have been received over the last
couple of hours, KAMX and MRMS mosaic radar data show 1-2 inch MESH
values, with MRMS also depicting 50 dBZ echoes extending up to 40
kft in the stronger storms. As such, the stronger cells that
propagate into a pristine airmass should continue to pose a severe
hail and damaging gust threat through the remainder of the
afternoon. By sunset, cooling of the boundary layer should reduce
buoyancy and result the gradual weakening of the storms.
