Mesoscale Discussion 0789 NWS Storm Prediction Center Norman OK 0358 AM CDT Wed May 15 2024 Areas affected...Parts of north/central FL Concerning...Tornado Watch 243... Valid 150858Z - 151030Z The severe weather threat for Tornado Watch 243 continues. SUMMARY...The threat for a couple tornadoes and isolated severe hail/wind will continue through the early morning. DISCUSSION...A band of convection along a weak surface boundary has evolved into multiple supercells across north-central FL early this morning, with a few persistent mesocyclones observed in radar data. Favorable moisture and buoyancy (MLCAPE near or above 2000 J/kg) and sufficient low-level shear/SRH (as noted on the KTBW VWP) will continue to support some tornado threat with any persistent supercell, in addition to the threat for isolated hail and damaging wind. With a persistent cumulus field extending southwestward from the ongoing band of convection toward the Gulf Coast north of Tampa Bay, occasional supercell redevelopment appears possible through the early morning. Storm coverage across southern and western portions of WW 243 may tend to increase with time, accompanied by an increasing severe threat across this area. ..Dean.. 05/15/2024 ...Please see www.spc.noaa.gov for graphic product...
