...HEAT ADVISORY IN EFFECT FROM 10 AM THIS MORNING TO 8 PM EDT
THIS EVENING...
...EXCESSIVE HEAT WATCH IN EFFECT FROM SUNDAY MORNING THROUGH
SUNDAY EVENING...

THE NATIONAL WEATHER SERVICE IN MOUNT HOLLY HAS ISSUED A HEAT
ADVISORY...WHICH IS IN EFFECT FROM 10 AM THIS MORNING TO 8 PM EDT
THIS EVENING. AN EXCESSIVE HEAT WATCH HAS ALSO BEEN ISSUED. THIS
EXCESSIVE HEAT WATCH IS IN EFFECT FROM SUNDAY MORNING THROUGH
SUNDAY EVENING. THE EXCESSIVE HEAT WATCH IS NO LONGER IN EFFECT. 

HIGH TEMPERATURES TODAY ARE FORECAST TO REACH THE MIDDLE 90S.
THESE TEMPERATURES COMBINED WITH HUMID CONDITIONS WILL PUSH THE
HEAT INDICES TO NEAR 100 DEGREES DURING THE AFTERNOON. THE
HIGHEST HEAT INDICES ARE EXPECTED TO OCCUR IN THE MORE URBANIZED
AREAS. LOW TEMPERATURES FRIDAY NIGHT ARE FORECAST TO ONLY DROP TO
THE MID AND UPPER 70S IN THE MORE URBANIZED AREAS.

HOWEVER, TEMPERATURES ARE EXPECTED TO BE A COUPLE OF DEGREES
COOLER ON SATURDAY, BUT MORE IMPORTANTLY, DRIER AIR WILL MOVE IN
BEHIND THE PASSAGE OF A COLD FRONT. THEREFORE, CONDITIONS ON
SATURDAY DO NOT SEEM TO WARRANT ANY HEAT ADVISORIES OR WARNINGS.

ON SUNDAY, HIGH PRESSURE WILL MOVE EASTWARD AND A SOUTHWESTERLY 
FLOW WILL RETURN. THIS WILL CAUSE AN INCREASE IN HUMIDITY ONCE
AGAIN. TEMPERATURES WILL REACH THE MIDDLE 90S. THE MAIN QUESTION
IS HOW HUMID IT WILL GET. CURRENT INDICATIONS ARE THAT HEAT INDEX
VALUES COULD REACH AROUND 100 DEGREES AGAIN. THEREFORE, AN
EXCESSIVE HEAT WATCH HAS BEEN ISSUED FOR SUNDAY.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

AN EXCESSIVE HEAT WATCH MEANS THAT A PROLONGED PERIOD OF HOT AND
HUMID WEATHER IS EXPECTED. THE COMBINATION OF HIGH TEMPERATURES
AND HIGH HUMIDITY LEVELS COULD CREATE A DANGEROUS SITUATION.

MAKE PREPARATIONS NOW TO ASSURE THAT ELDERLY RELATIVES AND
NEIGHBORS ARE PREPARED FOR THE UPCOMING HEAT.
