NWS STORM PREDICTION CENTER NORMAN OK
0501 PM CDT FRI SEP 05 2025
AREAS AFFECTED...THE UPPER OH VALLEY
CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE
VALID 052201Z - 060000Z
PROBABILITY OF WATCH ISSUANCE...40 PERCENT
SUMMARY...ISOLATED STRONG TO SEVERE THUNDERSTORMS ARE POSSIBLE THIS
EVENING TO THE NORTHEAST OF RECENTLY ISSUED WW 606, MOST PROBABLE
ACROSS WESTERN TO NORTHERN WEST VIRGINIA.
DISCUSSION...INITIALLY SMALL DISCRETE CELLS HAVE BEEN SLOW TO
DEVELOP IN THE UPPER OH VALLEY REGION OF SOUTHEAST OH AND WESTERN
WV, WHERE MLCAPE IS PROGRESSIVELY WEAKER WITH NORTHEAST EXTENT FROM
THE TN VALLEY. BUT WITH STRONGER SOUTHWESTERLY TO WEST-SOUTHWESTERLY
DEEP-LAYER SHEAR, THERE IS POTENTIAL FOR A FEW OF THESE CELLS TO
ACQUIRE MID-LEVEL ROTATION AND PERHAPS GROW UPSCALE INTO A SMALL
CLUSTER. THE MOST PROBABLE CORRIDOR FOR THIS TO OCCUR IS ACROSS
WESTERN TO NORTHERN WV WHERE 80S SURFACE TEMPERATURES ARE COMMON.
COOLER TEMPERATURES AND DEW POINTS INTO PA SHOULD SPATIALLY CONFINE
SEVERE POTENTIAL FROM FAR SOUTHWEST PA SOUTHWESTWARD.
