WESTERN HALF TO TWO THIRDS OF THE CWA. CLOUDS CLEARING OUT EARLIER
WHERE THE WATCH IS IN PLACE HAS ALLOWED MLCAPES TO INCREASE UP TO
AROUND 1500 J/KG ALONG THE WESTERN BORDER OF THE CWA...ALONG WITH
0-1 KM STORM RELATIVE HELICITY UP TO AROUND 400 M2/S2 COURTESY OF
WARM FRONT OVER THIS AREA. CELL SHOWING PERSISTENT STRONG MID
LEVEL ROTATION NEARING WESTERN PASSAIC COUNTY AS OF 730 PM IS THE
IMMEDIATE CONCERN AND LIKELY HAS A HISTORY OF DAMAGE IN
NORTHEASTERN PA. FURTHER DEVELOPMENT OF CELLS POSSIBLE WITH PLENTY
OF CAPE FOR THE NEXT COUPLE OF HOURS AND ROUGHLY 40 KTS OF BULK
SHEAR.
WITH WARM AND HUMID AIRMASS...WILL EXPECT FOG TO DEVELOP...MAINLY

20-22C...A HAZY...HOT AND HUMID DAY ON TAP FOR SAT. HIGH TEMPS

MOVE INTO THE REGION IN THE AFTERNOON...TOUCHING OFF AFTERNOON AND

IN THE MID TO UPPER 60S AND HIGHS WILL BE IN THE LOWER 90S
IN/AROUND NYC AND IN THE UPPER 80S TO AROUND 90 ELSEWHERE. THINK

CARRY CHANCE POPS IN THE AFTERNOON.
