Mesoscale Discussion 0314
NWS Storm Prediction Center Norman OK
1151 AM CDT Thu Apr 01 2021
Areas affected...Southeastern Florida
Concerning...Severe potential...Watch unlikely
Valid 011651Z - 011815Z
Probability of Watch Issuance...20 percent
SUMMARY...Scattered strong/severe storms are expected along a cold
front this afternoon and evening. Damaging wind gusts and marginally
severe hail will be possible. A weather watch is unlikely.
DISCUSSION...1630Z obs showed an east-west oriented cold front
bisecting the Florida Peninsula south of Tampa. Surface temperatures
have warmed into the 80s F south of the front over the last few
hours. The warm temperatures in combination with surface dewpoints
in the upper 60s F are supporting MLCAPE between 1000-1500 J/kg.
Continued destabilization should support scattered storm development
along the front over the next couple of hours. Westerly mid-level
flow from the upper trough over the Mid Atlantic is displaced behind
the front suggesting limited shear overlap with the warm sector.
This should result in a messy storm mode of predominately multi-cell
clusters. Damaging wind gusts from wet microbursts and some
marginally severe hail should be the primary low-end severe threats
through this afternoon. A watch is not anticipated but trends will
be monitored.
