NWS STORM PREDICTION CENTER NORMAN OK
1153 PM CDT SUN MAY 18 2025
AREAS AFFECTED...NORTHERN MISSISSIPPI...NORTHWEST ALABAMA
CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY
VALID 190453Z - 190730Z
PROBABILITY OF WATCH ISSUANCE...20 PERCENT
SUMMARY...A POTENTIAL FOR SEVERE GUSTS AND HAIL WILL CONTINUE OVER
THE NEXT COUPLE OF HOURS ACROSS NORTHEAST MISSISSIPPI AND NORTHWEST
ALABAMA. THE THREAT WILL LIKELY REMAIN ISOLATED, AND WATCH ISSUANCE
IS NOT EXPECTED.
DISCUSSION...THE LATEST RADAR IMAGERY SHOWS A SMALL CLUSTER OF
STRONG TO SEVERE STORMS OVER NORTHEASTERN MISSISSIPPI. THIS ACTIVITY
IS LOCATED JUST TO THE NORTH OF A POCKET OF MODERATE INSTABILITY,
WHERE MLCAPE IS ESTIMATED BY THE RAP IN THE 2000 TO 2500 J/KG RANGE.
THE STORMS ARE BEING SUPPORTED BY LARGE-SCALE ASCENT ASSOCIATED WITH
A SUBTLE SHORTWAVE TROUGH, AND BY WARM ADVECTION. THE RAP ALSO HAS
MODERATE DEEP-LAYER SHEAR, WHICH IS SAMPLED BY THE GWX WSR-88D VWP
IN NORTHEAST MISSISSIPPI. THE ENVIRONMENT WILL SUPPORT ISOLATED
SEVERE WIND GUSTS AND HAIL. HOWEVER, THE SEVERE THREAT IS EXPECTED
TO REMAIN TOO ISOLATED FOR WEATHER WATCH ISSUANCE.
