MESOSCALE DISCUSSION 0237
NWS STORM PREDICTION CENTER NORMAN OK
0233 PM CDT SAT MAR 14 2026
AREAS AFFECTED...PORTIONS OF THE SOUTHERN FLORIDA PENINSULA
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 141933Z - 142130Z
PROBABILITY OF WATCH ISSUANCE...20 PERCENT
SUMMARY...SCATTERED THUNDERSTORMS ONGOING ALONG TYPICAL SEA BREEZE
FRONTS MAY BRIEFLY ORGANIZE WITH THE POTENTIAL FOR SPORADIC HAIL AND
SOME DAMAGING GUSTS. A WW IS UNLIKELY.
DISCUSSION...AS OF 1925 UTC, REGIONAL RADAR AND SATELLITE DATA
SHOWED SCATTERED THUNDERSTORMS HAD DEVELOPED AND BEGUN TO MATURE
ALONG TYPICAL SEA BREEZE BOUNDARY CORRIDORS ACROSS THE SOUTHERN AND
EASTERN FL PENINSULA. STRONG SURFACE HEATING AMID UPPER 60S TO LOW
70S F SURFACE DEWPOINTS WAS SUPPORTING 1500-2000 J/KG OF MLCAPE.
WHILE DEEP-LAYER FLOW IS MODEST, EASTERLY LOW-LEVEL FLOW AND 180
DEGREE OPPOSED 20-25 KT WINDS ALOFT ARE SUPPORTING SUFFICIENT
DEEP-LAYER SHEAR (25-30 KT) FOR ORGANIZED MULTICELLS AND SOME
TRANSIENT SUPERCELL STRUCTURES. GIVEN THE STORM MODE AND FAVORABLE
THERMODYNAMICS, A FEW OF THE STRONGER CELLS APPEAR CAPABLE OF
SPORADIC HAIL. ADDITIONALLY, HIGH PWAT CONTENT COULD SUPPORT A FEW
STRONGER DOWNDRAFTS CAPABLE OF DAMAGING GUSTS.
CURRENT TRENDS AND RECENT CAM GUIDANCE SUGGESTS CONVECTION SHOULD
INCREASE IN COVERAGE THROUGH THIS AFTERNOON ACROSS THE EASTERN AND
SOUTHERN PARTS OF THE FL PENINSULA. STORMS MAY INTERMITTENTLY
STRENGTHEN AND WEAKEN WITH SOME RISK FOR LOCALIZED SEVERE WEATHER.
GIVEN OVERALL STORM ORGANIZATION WILL BE TRANSIENT, THE SEVERE RISK
APPEARS ISOLATED ENOUGH THAT A WATCH WILL NOT BE NEEDED.
