AREAS AFFECTED...PORTIONS OF EASTERN PENNSYLVANIA INTO NORTHWESTERN
NEW JERSEY AND SOUTHERN NEW YORK
CONCERNING...SEVERE THUNDERSTORM WATCH 233...
VALID 062037Z - 062200Z
THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 233
CONTINUES.
SUMMARY...ADDITIONAL INSTANCES OF DAMAGING GUSTS AND PERHAPS HAIL
REMAIN POSSIBLE WITH THE STRONGER STORMS. A TORNADO MAY STILL OCCUR
WITH STORMS AHEAD OF A PRE-FRONTAL BOUNDARY.
DISCUSSION...A PRIMARY ARCHING BAND OF STRONG THUNDERSTORMS PERSISTS
AHEAD OF A PSEUDO-DRYLINE PRE-FRONTAL BOUNDARY ACROSS FAR EASTERN
PA, WITH TEMPERATURES RISING INTO THE UPPER 70S F AMID 10 DEGREE F
DEWPOINT DECREASES AS THE BOUNDARY PASSES. THESE PRE-FRONTAL STORMS
HAVE BEEN THE MOST ORGANIZED SO FAR, WITH MULTIPLE INSTANCES OF
LOW-LEVEL ROTATION DETECTED AND AN APPARENT TORNADO REPORTED IN THE
PAST HOUR. THE BEST CHANCE FOR AN ADDITIONAL TORNADO REMAINS WITH
THESE STORMS, ALONG THE PA/NJ/NY BORDERS, BEFORE THE ONGOING STORMS
MOVE INTO A MORE STABLE AIRMASS. OTHERWISE, STRONG WIND GUSTS AND
PERHAPS HAIL MAY DEVELOP WITH THE STRONGER STORMS TO THE WEST OF THE
PRE-FRONTAL BOUNDARY.
