NWS STORM PREDICTION CENTER NORMAN OK
1056 AM CDT SUN AUG 16 2026
AREAS AFFECTED...CENTRAL AND EASTERN OHIO INTO WESTERN PENNSYLVANIA
AND NORTHWEST WEST VIRGINIA
CONCERNING...SEVERE POTENTIAL...WATCH LIKELY
VALID 161556Z - 161700Z
PROBABILITY OF WATCH ISSUANCE...80 PERCENT
SUMMARY...THE THREAT FOR SEVERE WEATHER IS EXPECTED TO INCREASE BY
EARLY TO MID AFTERNOON WITH DAMAGING WIND GUSTS BEING THE PRIMARY
HAZARD. A SEVERE THUNDERSTORM WATCH IS LIKELY.
DISCUSSION...AHEAD OF AN MCV MOVING THROUGH FAR SOUTHEAST LOWER MI,
CLUSTERS OF THUNDERSTORMS HAVE PERSISTED THIS MORNING OVER NORTHWEST
INTO WEST-CENTRAL OH. DOWNSTREAM FROM THAT CONVECTION, A CORRIDOR OF
RELATIVELY FEWER CLOUDS SHOULD ALLOW FOR STRONGER DAYTIME HEATING TO
OCCUR THIS AFTERNOON. WHEN COUPLED WITH BOUNDARY-LAYER DEW POINTS IN
THE LOW TO MID-70S F, DAYTIME HEATING IS EXPECTED TO ERODE REMAINING
CONVECTIVE INHIBITION, WITH MLCAPE INCREASING TO 1500-2500+ J/KG.
THAT DESTABILIZATION PROCESS SHOULD ALLOW THE ONGOING STORMS TO
INTENSIFY BY EARLY TO MID AFTERNOON FROM EASTERN OH INTO WESTERN PA
AND NORTHWEST WV.
THE CURRENT IND VWP IS SAMPLING A BELT OF 30-40 KT WESTERLY WINDS IN
THE 1-5 KM LAYER, WHICH WILL CONDITIONALLY SUPPORT COLD POOL
ORGANIZATION WITH AN ATTENDANT DAMAGING WIND RISK. A BRIEF TORNADO
IS POSSIBLE, THOUGH THE VEERED LOW-LEVEL WINDS ARE EXPECTED TO LIMIT
THE MAGNITUDE OF LOW-LEVEL SHEAR AND A RESULTANT GREATER RISK.
