Mesoscale Discussion 0672 NWS Storm Prediction Center Norman OK 0459 PM CDT Sat May 03 2025 Areas affected...Southern Alabama...the western Florida Panhandle...and far eastern Mississippi Concerning...Severe potential...Watch possible Valid 032159Z - 040000Z Probability of Watch Issuance...40 percent SUMMARY...Thunderstorms developing along and ahead of an approaching cold front may intensify to severe limits and pose a damaging wind/large hail threat through the early evening hours. Watch issuance is possible if severe thunderstorm coverage sufficiently increases. DISCUSSION...Scattered thunderstorms have begun developing across southwest AL into far southeastern MS as a cold front continues to push east/southeast into the region. Ahead of the front, broken cloud cover has allow temperatures to warm into the mid/upper 70s, which based on recent RAP forecast soundings, should be supporting MLCAPE values upwards of 1000-1500 J/kg with very limited inhibition. Regional VWPs are sampling somewhat straight hodographs with 0-6 km BWD values of around 40-45 knots, which is supportive of supercells capable of producing large hail (1.0 to 1.75 inches in diameter). However, recent radar trends show widespread new cell development with destructive storm interactions ongoing. This may limit the overall coverage of strong/severe storms. With time, upscale growth/storm interactions along the front should promote clustering with an attendant damaging wind threat across southeast AL and parts of the FL Panhandle. Convective trends will continue to be monitored, and watch issuance is possible if the coverage of severe storms continues to increase. ..Moore/Thompson.. 05/03/2025 ...Please see www.spc.noaa.gov for graphic product...
