Mesoscale Discussion 0767 NWS Storm Prediction Center Norman OK 0221 PM CDT Sun May 11 2025 Areas affected...central Florida northward toward southeast Georgia Concerning...Severe potential...Watch unlikely Valid 111921Z - 112145Z Probability of Watch Issuance...20 percent SUMMARY...Storms are forecast to increase in coverage throughout the afternoon from the central Florida Peninsula into northeast Florida and southeast Georgia. DISCUSSION...Storms are currently increasing east of Tampa to west of Okeechobee where strong heating has led to strong instability. The southerly flow regime should support a north/northeast movement to this development, affecting the remainder of central into northeastern Florida. Breaks in the clouds in those downstream areas are developing, and this should further increase instability. Although temperatures aloft are not as cool as previous days, MUCAPE over 2000 J/kg and deep-layer shear of 35-40 kt will support cellular storm mode with sporadic hail > 1.00" expected. Locally strong to damaging gusts cannot be ruled out as well, especially with any merging outflows. ..Jewell/Mosier.. 05/11/2025 ...Please see www.spc.noaa.gov for graphic product...
