MESOSCALE DISCUSSION 2187
NWS STORM PREDICTION CENTER NORMAN OK
0106 AM CDT MON OCT 27 2025
AREAS AFFECTED...PARTS OF THE WESTERN FLORIDA PANHANDLE
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 270606Z - 270830Z
PROBABILITY OF WATCH ISSUANCE...20 PERCENT
SUMMARY...A LOCALIZED RISK OF BRIEF TORNADOES/WATERPSOUTS WILL
CONTINUE THROUGH THE EARLY MORNING HOURS WHILE SPREADING EASTWARD
ACROSS THE WESTERN FLORIDA PANHANDLE. GIVEN THE LOCALIZED AND AND
CONDITIONAL NATURE OF THE RISK, A WATCH IS NOT EXPECTED.
DISCUSSION...THE LATEST SURFACE ANALYSIS SHOWS A MESOSCALE
LOW/FRONTAL WAVE OVER THE FAR WESTERN FL PANHANDLE. A MARINE FRONT
EXTENDS EASTWARD ACROSS THE REMAINDER OF THE SOUTHERN FL PANHANDLE
-- DEMARCATING THE NORTHERN BOUND OF UPPER 60S TO LOWER 70S
BOUNDARY-LAYER DEWPOINTS. AHEAD OF THE FRONTAL WAVE, THE EVX VWP IS
SAMPLING 35-KT EAST-SOUTHEASTERLY FLOW AT 0.5 KM AGL, WHICH IS
YIELDING A CLOCKWISE-CURVED LOW-LEVEL HODOGRAPH (150-180 M2/S2 0-500
M SRH PER EVX). AS THE FRONTAL WAVE TRACKS EASTWARD ALONG THE MARINE
FRONT, A FORCED CONFLUENCE ZONE/LOW-LEVEL WARM-ADVECTION PLUME WILL
CONTINUE SUPPORTING THUNDERSTORM DEVELOPMENT ACROSS THE FL PANHANDLE
THROUGH THE EARLY MORNING HOURS. GIVEN THE IMPLIED ENHANCED
LOW-LEVEL STREAMWISE VORTICITY AND RELATIVELY MOIST BOUNDARY LAYER,
TRANSIENT SUPERCELL STRUCTURES WILL CONTINUE TO POSE A RISK OF BRIEF
TORNADOES/WATERSPOUTS. HOWEVER, POOR LAPSE RATES AND A VERY NARROW
ZONE OF SURFACE-BASED EFFECTIVE-INFLOW-LAYER AIR SHOULD KEEP THE
OVERALL THREAT LOCALIZED AND CONDITIONAL -- PRECLUDING THE NEED FOR
A WATCH.
