NWS STORM PREDICTION CENTER NORMAN OK
0452 AM CST SUN FEB 16 2025
AREAS AFFECTED...NORTHEAST GEORGIA...SOUTH CAROLINA
CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE
VALID 161052Z - 161315Z
PROBABILITY OF WATCH ISSUANCE...40 PERCENT
SUMMARY...ISOLATED SEVERE GUSTS ARE EXPECTED THIS MORNING ACROSS
PARTS WESTERN AND CENTRAL SOUTH CAROLINA. WEATHER WATCH ISSUANCE
REMAINS UNCERTAIN.
DISCUSSION...MOSAIC RADAR IMAGERY CURRENTLY SHOWS A SQUALL LINE
ACROSS PARTS OF CENTRAL GEORGIA EXTENDING NORTHEASTWARD INTO FAR
WESTERN SOUTH CAROLINA. THE LINE IS BEING SUPPORTED BY STRONG
LARGE-SCALE ASCENT ASSOCIATED WITH AN APPROACHING TROUGH, AND BY
FORCING ALONG A FAST-MOVING COLD FRONT. AHEAD OF THE LINE,
INSTABILITY IS VERY WEAK, WITH SURFACE DEWPOINTS IN THE 50S F ACROSS
WESTERN SOUTH CAROLINA AND NORTHEAST GEORGIA. THE LATEST WSR-88D VWP
AT GREENVILLE/SPARTANBURG HAS ABOUT 85 KNOT OF 0-6 KM SHEAR WITH 40
TO 50 KNOTS OF SOUTH-SOUTHWESTERLY FLOW LOCATED JUST ABOVE THE
SURFACE. AN ISOLATED WIND-DAMAGE THREAT WILL BE POSSIBLE WITH THE
STRONGER CELLS WITHIN THE LINE. GIVEN THE VERY STRONG LOW-LEVEL
SHEAR, MESO-SCALE VORTICIES WILL BE POSSIBLE IN THE LINE WITH
EMBEDDED CELLS THAT REMAIN SURFACE-BASED. HOWEVER, FORECAST
SOUNDINGS IN FAR WESTERN SOUTH CAROLINA HAVE A SHARP NEAR SURFACE
TEMPERATURE INVERSION, WHICH SHOULD KEEP ANY SEVERE THREAT ISOLATED
AND LOCALIZED.
