MD 0263 CONCERNING SEVERE POTENTIAL…WATCH POSSIBLE FOR CENTRAL INTO NORTHEAST FL PENINSULA
Mesoscale Discussion 0263 NWS Storm Prediction Center Norman OK 1147 AM CDT Wed Mar 16 2022 Areas affected...Central into northeast FL Peninsula Concerning...Severe potential...Watch possible Valid 161647Z - 161815Z Probability of Watch Issuance...60 percent SUMMARY...Scattered strong/severe thunderstorm development is expected this afternoon. The strongest storms will be capable of hail, locally damaging wind, and perhaps a tornado. Watch issuance is possible by 18Z. DISCUSSION...Substantial diabatic heating/destabilization is underway across most of the FL Peninsula early this afternoon, with convection recently increasing across the central/northeast FL Peninsula. As MLCINH erodes this afternoon, an increase in storm coverage/intensity is expected, mainly along/east of the midlevel dryslot attendant to the mid/upper-level cyclone over AL. MLCAPE is expected to increase into the 1500-2000 J/kg range this afternoon, as temperatures warm into the 80s F. Relatively strong midlevel southwesterly flow is supporting effective shear of 35-45 kt, sufficient for a few supercell structures with any sustained discrete convection. As storms mature this afternoon, the threat for large hail and locally damaging wind gusts will increase. While low-level shear is relatively limited, a brief tornado or two will also be possible with any stronger supercell. Watch issuance is possible by 18Z in response to this threat. ..Dean/Bunting.. 03/16/2022 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...MLB...TBW...JAX...
