AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LITTLE ROCK AR
336 PM CDT WED AUG 20 2003

...MAIN CONCERN IS THE HEAT...

HIGH PRESSURE CONTINUES ACROSS THE AREA. HOT TEMPERATURES ALSO
CONTINUE UNDERNEATH THE AREA OF HIGH PRESSURE. THE TEMPERATURE
SOARED TO 101 DEGREES THIS AFTERNOON AT NORTH LITTLE ROCK. THE SKY WAS
PARTLY CLOUDY IN MOST LOCATIONS. HOWEVER...ISOLATED THUNDERSTORMS
HAVE BEGUN TO DEVELOP ACROSS THE CWFA. TEMPERATURES WILL AGAIN REACH
NEAR 100 DEGREES TOMORROW WITH DEW POINTS IN THE MID 70S. WILL
THEREFORE CONTINUE THE HEAT ADVISORY FOR ANOTHER DAY.

THE AREA OF HIGH PRESSURE WILL SLIDE TO THE WEST TONIGHT AND BRING
MORE OF A NORTHWEST FLOW ACROSS THE AREA. A COLD FRONT IN THE UPPER
MIDWEST WILL WORK ITS WAY INTO NORTH ARKANSAS ON FRIDAY. THIS WILL
INCREASE THE CHANCE OF SHOWERS AND THUNDERSTORMS A BIT ALONG AND
AHEAD OF THE FRONT. THE FRONT IS EXPECTED TO STALL NEAR THE
LOUISIANA BORDER BY SUNDAY MORNING. THEREFORE...A SLIGHT CHANCE OF
SHOWERS AND THUNDERSTORMS IS EXPECTED THROUGH EARLY NEXT WEEK IN THE
SOUTH PART OF THE CWFA.

COOLER TEMPERATURES ARE EXPECTED FOR THE WEEKEND BEHIND THE FRONT.
GUIDANCE TEMPERATURES ARE A BIT TOO LOW FOR TOMORROW SO WILL GO A
COUPLE OF DEGREES WARMER THAN THAT.
