TEMPERATURES CLIMBING INTO THE UPPER 80S TO NEAR 90 OVER CENTRAL AND 
SOUTHERN NEW JERSEY AWAY FROM THE COAST...SOUTHEAST 
PENNSYLVANIA...ALL OF DELAWARE AWAY FROM THE COAST AND THE NORTHERN 
MARYLAND EASTERN SHORE WILL COMBINE WITH DEWPOINTS AROUND 70 TO 
GENERATE HEAT INDICES IN THE MID 90S TO NEAR 100 THIS AFTERNOON. 

THE HEAT INDEX IS A MEASURE OF HOW HOT IT SEEMS DUE TO THE 
COMBINATION OF HEAT AND MOISTURE IN THE AIR. HIGHER LEVELS OF HEAT 
AND MOISTURE INHIBIT THE BODY'S ABILITY TO COOL ITSELF THROUGH THE 
EVAPORATION OF PERSPIRATION. 

A COLD FRONT WILL PASS THROUGH THE AREA LATE THIS AFTERNOON AND THIS 
EVENING...BRINGING SOMEWHAT COOLER AND NOTICEABLY DRIER AIR WITH IT.

THAT COLD FRONT ALSO MAY CAUSE ISOLATED SEVERE THUNDERSTORMS OVER 
CENTRAL AND SOUTHERN DELAWARE...ADJACENT PORTIONS OF THE MARYLAND 
EASTERN SHORE...AND EXTREME SOUTHERN NEW JERSEY LATE THIS AFTERNOON 
AND EARLY THIS EVENING. THE FRONT MAY INTERACT WITH THE VERY WARM 
AND MOIST AIR AND MARGINALLY FAVORABLE CONDITIONS ALOFT TO GENERATE 
ISOLATED STORMS CAPABLE OF PRODUCING DAMAGING WINDS.
