AREAS AFFECTED...ERN OH...WRN PA AND EXTREME SWRN NY

CONCERNING...SEVERE THUNDERSTORM WATCH 235...

VALID 052033Z - 052200Z

THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 235
CONTINUES.

SUMMARY...STORMS WILL CONTINUE TO POSE A RISK FOR ISOLATED STRONG TO
DAMAGING WIND GUSTS AND HAIL THROUGH 22Z FROM ERN OH INTO WRN PA. A
LIMITED SEVERE THREAT MAY EXPAND A BIT FARTHER EAST BEYOND WW 235
INTO SWRN NY AND NWRN PA...BUT OVERALL THREAT DOWNSTREAM IS NOT
EXPECTED TO BECOME SUFFICIENT FOR AN ADDITIONAL WW. HOWEVER...WW CAN
BE LOCALLY EXTENDED AS NEEDED FARTHER EAST INTO PITTSBURGH CWA.

DISCUSSION...A BROKEN BAND OF STRONG TO SEVERE STORMS CONTINUES FROM
EXTREME NW PA THROUGH ERN OH MOVING EAST AT AROUND 35 KT. STRONGEST
STORMS REMAIN OVER NWRN PA AND NERN OH WHERE LOW-LEVEL CONVERGENCE
IS MAXIMIZED ALONG A LAKE-ENHANCED OUTFLOW BOUNDARY. THE STORMS ARE
EMBEDDED WITHIN 40-45 KT 0-6 KM SHEAR AND SOME MID-LEVEL ROTATION
HAS BEEN OBSERVED WITH SOME OF THE CELLS. ACTIVITY WILL CONTINUE TO
POSE A THREAT FOR A FEW STRONG TO DAMAGING WIND GUSTS AND HAIL NEXT
FEW HOURS FROM ERN OH INTO EXTREME WRN NY AND WRN PA. THOUGH A
LIMITED SEVERE THREAT MAY EXTEND BEYOND WW 235...STORMS ARE EXPECTED
TO WEAKEN WITH EWD EXTENT INTO WRN PA THROUGH WRN NY WHERE AN
EXPANSIVE CLOUD SHIELD HAS RESULTED IN WEAKER INSTABILITY.
