A COLD FRONT WAS MOVING EASTSOUTHEASTWARD THROUGH CENTRAL NEW YORK AND
CENTRAL PENNSYLVANIA AT MIDAFTERNOON. THE VERY WARM HUMID AND UNSTABLE
AIRMASS IN FRONT OF THIS FRONT IS A PRIME AREA FOR THE FORMATION OF

AND LOW 90S...AND HUMIDITIES WERE QUITE HIGH. AT 3 PM...A STRONG

CENTRAL NEW JERSEY COULD BE THE FOCUS OF MUCH OF THE STORM ACTIVITY
THIS AFTERNOON AND EVENING. HOWEVER...ALL AREA RESIDENTS NEED TO

EVENING.

AFTER THE FRONT MOVES SOUTHEAST OF OUR AREA TONIGHT...WE LOOK FOR
EQUALLY WARM BUT SOMEWHAT LESS HUMID WEATHER FOR TUESDAY. CONTINUED

RETURN TO SHOWER CHANCES FOR WEDNESDAY...BUT TEMPERATURES COULD EASE A
BIT BY THEN.
