VALID 250100Z - 251200Z
...NO SVR TSTM AREAS FORECAST...
...CENTRAL GULF COAST STATES...
TROPICAL DEPRESSION FAY IS EXPECTED TO MOVE LITTLE OVER FAR SOUTHERN
MS THROUGH EARLY MONDAY. WHILE LOSS OF DIABATIC HEATING WILL LIMIT
UPDRAFT LONGEVITY/VIGOR THE REMAINDER OF THE NIGHT...PERIPHERAL
ENVELOPE OF MODERATELY STRONG LOW LEVEL SHEAR /ALBEIT WEAKENING/
WILL MAINTAIN A MARGINAL THREAT FOR ISOLATED/BRIEF TORNADOES ACROSS
CENTRAL/NORTHERN AL INTO NORTHERN MS. FARTHER SOUTH...AS A MID LEVEL
VORT LOBE ON THE SOUTHERN PERIPHERY OF FAY ROTATES EASTWARD ALONG
THE COAST OVERNIGHT...SOMEWHAT INCREASING SOUTHERLY LOW LEVEL FLOW
AND PROXIMITY OF THE WARM/MOIST GULF COULD RESULT IN A LATE NIGHT
ISOLATED TORNADO RISK ACROSS SOUTHERN AL/FL PANHANDLE.
...NORTH CENTRAL HIGH PLAINS...
LATEST SURFACE ANALYSIS REFLECTS A POST-FRONTAL SOUTHEASTERLY LOW
LEVEL UPSLOPE REGIME ACROSS THE REGION...WITH MOIST 50S F DEWPOINTS
AS FAR WEST AS THE CO/WY FRONT RANGE EARLY THIS EVENING. AS ALREADY
IS OCCURRING ROUGHLY FROM THE RAPID CITY VICINITY SOUTHWARD TO THE
NM RATON MESA AREA...ISOLATED STRONG/SEVERE TSTMS WILL CONTINUE TO
DEVELOP/SPREAD SOUTHEASTWARD ACROSS THE HIGH PLAINS OVER THE NEXT
FEW HOURS. SOME SEVERE HAIL AND PERHAPS A STRONG WIND GUST OR TWO
WILL REMAIN POSSIBLE THROUGH MID EVENING...ALTHOUGH MODEST VERTICAL
SHEAR AND A DECOUPLING BOUNDARY LAYER WILL LIMIT THE OVERALL RISK.
THE LANDSPOUT THREAT JUST EAST/SOUTHEAST OF THE DENVER AREA WILL END
IN THE SHORT TERM WITH LOSS OF DAYTIME HEATING.
