MD 2260 CONCERNING SEVERE POTENTIAL…WATCH UNLIKELY FOR PORTIONS OF THE CENTRAL FLORIDA PENINSULA
Mesoscale Discussion 2260 NWS Storm Prediction Center Norman OK 1043 AM CST Wed Dec 11 2024 Areas affected...portions of the central Florida Peninsula Concerning...Severe potential...Watch unlikely Valid 111643Z - 111815Z Probability of Watch Issuance...20 percent SUMMARY...Isolated severe gusts and perhaps a tornado cannot be ruled out this afternoon. A WW issuance is not expected. DISCUSSION...A surface cold front is rapidly approaching the FL Peninsula, preceded by a loosely organized QLCS. These storms are approaching a gradually destabilizing airmass, where surface temperatures are exceeding 80 F amid 70 F dewpoints (supporting 1500 J/kg MLCAPE). While deep-layer shear and some low-level shear also precedes the line, deep-layer ascent will continue to drift away from FL, so shear should gradually weaken through the day. However, a brief window of opportunity may exist for the buoyancy/shear parameter space to briefly coincide to support a couple of damaging gusts or a tornado with the stronger updrafts. Nonetheless, the severe threat should remain isolated and a WW issuance is unlikely. ..Squitieri/Hart.. 12/11/2024 ...Please see www.spc.noaa.gov for graphic product...
