AREAS AFFECTED...WESTERN INTO CENTRAL NEW YORK AND NORTH-CENTRAL
PENNSYLVANIA
CONCERNING...SEVERE THUNDERSTORM WATCH 552...
VALID 101544Z - 101745Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 552
CONTINUES.
SUMMARY...DAMAGING WIND POTENTIAL MAY INCREASE EARLY THIS AFTERNOON
WITH STORMS LOCATED IMMEDIATELY AHEAD OF AN MCV. AN ADDITIONAL
DOWNSTREAM WATCH MAY BECOME NECESSARY.
DISCUSSION...AHEAD OF A WELL-DEFINED MCV, A BROKEN BAND OF
THUNDERSTORMS HAS PERSISTED THIS MORNING ACROSS PORTIONS OF WESTERN
NY AND NORTHWEST PA. CONSIDERABLE CLOUD COVER HAS LIMITED DAYTIME
HEATING AND RESULTANT AIR MASS DESTABILIZATION SO FAR TODAY.
HOWEVER, THINNER CLOUDS ARE ALLOWING FOR STRONGER DAYTIME HEATING
ACROSS PORTIONS OF CENTRAL NY INTO NORTH-CENTRAL PA, WHICH SHOULD
ALLOW FOR GREATER DESTABILIZATION TO OCCUR WITH STEEPENING LOW-LEVEL
LAPSE RATES.
DYNAMIC FORCING ASSOCIATED WITH THE MCV IS LIKELY TO SUSTAIN ONGOING
STORMS, WHICH MAY INTENSIFY AS THEY CONTINUE EAST AND ENCOUNTER AN
INCREASINGLY UNSTABLE ENVIRONMENT. EARLIER VWP OBSERVATIONS NEAR
CLEVELAND, OH AND CURRENT STORM MOTIONS OF AROUND 40 KT ARE
SUGGESTIVE OF A BELT OF ENHANCED WESTERLY FLOW, GENERALLY IN THE 1-4
KM LAYER, WHICH COUPLED WITH STEEPENING LOW-LEVEL LAPSE RATES, MAY
SUPPORT AN INCREASED POTENTIAL FOR DAMAGING WIND GUSTS EARLY THIS
AFTERNOON.
