AREAS AFFECTED...CENTRAL AND EASTERN OHIO INTO NORTHERN WEST
VIRGINIA AND WESTERN PARTS OF NEW YORK AND PENNSYLVANIA
CONCERNING...SEVERE THUNDERSTORM WATCH 614...
VALID 221950Z - 222145Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 614
CONTINUES.
SUMMARY...THE THREAT FOR MAINLY DAMAGING WIND GUSTS IS EXPECTED TO
CONTINUE ACROSS THE WATCH AREA LATE THIS AFTERNOON INTO EVENING.
DISCUSSION...MULTIPLE BANDS OF STRONG TO SEVERE THUNDERSTORMS ARE
ONGOING WITHIN LOW-LEVEL CONFLUENCE ZONES PRECEDING THE SYNOPTIC
COLD FRONT. AS OF 1945Z, THE MOST INTENSE CONVECTION WAS LOCATED
OVER FAR EASTERN OH, WHERE SEVERAL INSTANCES OF WIND DAMAGE HAVE
BEEN REPORTED. LATEST MESOANALYSIS INDICATES A PLUME OF STEEP
LOW-LEVEL LAPSE RATES IN EXCESS OF 8 C/KM HAS DEVELOPED AHEAD OF
THAT CONVECTIVE BAND, WHICH SHOULD ALLOW THE DAMAGING WIND THREAT TO
SPREAD INTO WESTERN PA OVER THE NEXT HOUR.
REGIONAL VWPS INDICATE GENERALLY WEAK LOW-LEVEL WINDS WITH POCKETS
OF AROUND 30 KT OF DEEP-LAYER SHEAR, WHICH MAY BE SUPPORTIVE OF MORE
ORGANIZED BOWING/LINE SEGMENTS CAPABLE OF A COMPARATIVELY GREATER
DAMAGING WIND THREAT. OTHERWISE, EXPECT STORMS TO REMAIN SOMEWHAT
DISORGANIZED AND SHORTER LIVED, BUT STILL CAPABLE OF LOCALLY
DAMAGING WIND GUSTS.
