SPECIAL WEATHER STATEMENT AND WEATHER MAP DISCUSSION FOR
EXTREME SOUTHEASTERN NEW YORK...NORTHEASTERN NEW JERSEY
AND SOUTHERN CONNECTICUT
NATIONAL WEATHER SERVICE NEW YORK
300 PM EDT TUE JUL 15 1997

...THE NATIONAL WEATHER SERVICE HAS EXTENDED THE HEAT ADVISORY
THROUGH THURSDAY FOR NEW YORK CITY AND THE URBAN AREAS OF
NORTHEASTERN NEW JERSEY FOR DAYTIME HEAT INDICIES NEAR 105 DEGREES
AND NIGHTTIME HEAT INDICIES REMAINING ABOVE 80 DEGREES...

THE HEAT AND OPPRESSIVE HUMIDITY WILL CONTINUE OVER THE NEXT COUPLE
OF DAYS AT LEAST. THIS COMBINATION WILL PUSH THE HEAT INDEX...A
MEASURE OF JUST HOW HOT IT FEELS...TO AROUND 105 DEGREES DURING THE
AFTERNOON HOURS OVER THE NEXT COUPLE OF DAYS. NIGHTTIME HEAT INDICIES
WILL REMAIN ABOVE 80 DEGREES.

USE CAUTION AND COMMON SENSE DURING THIS ONGOING HEAT WAVE. DRINK
PLENTY OF FLUIDS...WEAR LOOSE AND LIGHT COLORED CLOTHING AND NEVER
LEAVE CHILDREN OR PETS IN AN ENCLOSED CAR FOR ANY LENGTH OF TIME. TRY
TO SPEND AS MUCH TIME AS YOU CAN IN COOLER PLACES. COASTAL LOCATIONS
WOULD BE A FAIRLY GOOD PLACE TO ESCAPE THE BRUNT OF THE HEAT AS
COOLING SEA BREEZES DEVELOP EACH DAY.

WITH REGARD TO OTHER ASPECTS OF THE WEATHER...ISOLATED THUNDERSTORMS
HAVE DEVELOPED NORTH AND WEST OF THE CITY. SOME OF THESE STORMS WILL
PRODUCE HEAVY RAINS...HAIL AND GUSTY WINDS INTO THE EVENING HOURS. AT
THIS TIME IT APPEARS THAT THEY WILL NOT MOVE INTO THE COASTAL AREAS
BEFORE THEY DISSIPATE WITH THE SETTING OF THE SUN.

OVERNIGHT SKIES WILL BE PARTLY CLOUDY BUT HAZY. TEMPERATURES WILL
STAY QUITE WARM AND CONDITIONS WILL REMAIN VERY MUGGY.

WEDNESDAY WILL FEATURE A MIX OF HAZY SUN AND CLOUDS. A WEAKENING COLD
FRONT APPROACHING FROM THE WEST WILL TRIGGER SOME ISOLATED
THUNDERSTORMS...MAINLY DURING THE AFTERNOON HOURS.

THIS FRONT BASICALLY FALLS APART ACROSS THE TRI-STATE REGION
WEDNESDAY NIGHT AND THURSDAY. AS SUCH THERE WILL NOT BE A SIGNIFICANT
CHANGE OF AIRMASS...MEANING TEMPERATURES AND HUMIDITY LEVELS WILL
REMAIN AT RATHER UNCOMFORTABLE LEVELS.

IT APPEARS THAT SOME REAL RELIEF FOR THE HEAT WAVE WILL ARRIVE
SATURDAY WHEN A FAIRLY DECENT COLD FRONT IS EXPECTED TO PASS THROUGH
THE AREA.
