...EXCESSIVE HEAT WARNING REMAINS IN EFFECT FOR TODAY AND 
TUESDAY...

THE HOTTEST AIR OF THE SUMMER IS EXPECTED TO BUILD OVER OUR REGION 
BEGINNING TODAY AND CONTINUING INTO TUESDAY AT LEAST. HERE WILL 
ALSO BE A MARKED INCREASE IN THE HUMIDITY LEVELS.  AS A RESULT, THE
NATIONAL WEATHER SERVICE HAS ISSUED AN EXCESSIVE HEAT WARNING FOR
TODAY AND ESPECIALLY FOR TUESDAY. THE WARNING INCLUDES THE FOLLOWING
COUNTIES.

IN SOUTHEASTERN PENNSYLVANIA, BUCKS, MONTGOMERY, CHESTER, DELAWARE 
AND PHILADELPHIA COUNTY.

IN NEW JERSEY, MERCER, NORTHWESTERN BURLINGTON, CAMDEN AND 
GLOUCESTER COUNTY.

IN NORTHERN DELAWARE, NEW CASTLE COUNTY.

FOR THE COUNTIES INCLUDED IN THE WARNING, THE CRITERIA FOR AN 
EXCESSIVE HEAT EVENT (A HEAT INDEX OF 100) IS LOWER THAN THAT FOR 
SURROUNDING AREAS DUE TO THE EXTENT OF DEVELOPMENT AND 
URBANIZATION.  HIGHLY URBANIZED AREAS TEND TO WARM QUITE EFFICIENTLY 
AS BUILDINGS AND PAVEMENT ABSORB THE HEAT.  THOSE SAME LOCATIONS 
COOL MORE SLOWLY AT NIGHT.  AS A RESULT, THE NIGHTTIME HOURS PROVIDE 
ONLY A LIMITED AMOUNT OF RELIEF FROM THE EXCESSIVE HEAT.

FOR THIS AFTERNOON, TEMPERATURES ARE FORECAST TO RISE INTO THE 
LOWER 90S WITH HEAT INDEX VALUES NEAR 100 OR SLIGHTLY HIGHER IN 
THE AFTERNOON AND EARLY EVENING. TUESDAY IS FORECAST TO BE THE
HOTTEST DAY OF THE SUMMER UP TO THIS POINT.  TEMPERATURES ARE
ANTICIPATED TO SOAR INTO THE MIDDLE AND UPPER 90S WITH HEAT INDEX
VALUES REACHING 105 TO 110.

LIMIT YOUR TIME OUT OF DOORS IF POSSIBLE, ESPECIALLY DURING THE HEAT 
OF THE AFTERNOON AND EARLY EVENING. BE SURE TO CHECK ON YOUR 
ELDERLY RELATIVES AND NEIGHBORS.  THE ELDERLY ARE MOST SUSCEPTIBLE 
TO HEAT RELATED HEALTH PROBLEMS.

A COLD FRONT IS FORECAST TO DROP DOWN FROM THE NORTHWEST ON 
WEDNESDAY.  THE TIMING OF THE CLOUDS AND PRECIPITATION ASSOCIATED 
WITH THE FRONT IS A LITTLE UNCERTAIN AT THIS TIME.  THEREFORE, 
TEMPERATURES MAY AGAIN HAVE AN OPPORTUNITY TO RISE WELL INTO THE 90S 
ON WEDNESDAY AFTERNOON AND THE EXCESSIVE HEAT WARNING MAY NEED TO BE 
EXTENDED FOR ONE ADDITIONAL DAY.

NOTICEABLY COOLER AIR IS EXPECTED TO BUILD DOWN BEHIND THE COLD 
FRONT FOR THURSDAY AND FRIDAY.
