NATIONAL WEATHER SERVICE LITTLE ROCK AR
341 PM CDT THU JUL 18 2002

MAIN CONCERN IS PRECIPITATION CHANCES.

AFTER A RAIN FILLED MORNING...SHOWERS AND THUNDERSTORMS HAVE
REDEVELOPED. A LARGE COMPLEX OF STORMS LOCATED FROM SOUTHERN
MISSOURI TO NORTHEAST OKLAHOMA...ASSOCIATED WITH THE UPPER LEVEL
TROUGH...IS MOVING INTO NORTH ARKANSAS.

THE UPPER LEVEL TROUGH WILL SLOWLY MOVE SOUTHEAST THROUGH SATURDAY.
THIS WILL BRING THE BEST CHANCE OF SHOWERS AND THUNDERSTORMS TO THE
NORTHEAST PORTION OF THE CWFA. MODELS ARE IN SIMILAR AGREEMENT WITH
THE AVN SHOWING HIGHER MOISTURE VALUES. I WILL TEND TOWARD THE DRIER
ETA MODEL. THE MOISTURE WILL MOVE OFF TO THE EAST SATURDAY NIGHT
INTO SUNDAY. SUNDAY AND MONDAY LOOK TO BE DRIER AS HIGH PRESSURE
BUILDS IN OVER THE AREA. ANOTHER TROUGH WILL MOVE IN ON NORTHWEST
FLOW ON TUESDAY AND BRING ADDITIONAL MOISTURE AND A CHANCE OF
SHOWERS AND THUNDERSTORMS. THIS CHANCE WILL LAST INTO WEDNESDAY AND
THURSDAY WITH SEVERAL SHORT WAVES MOVING THROUGH THE AREA.

TEMPERATURES WILL BE SLOW TO WARM UP WITH ALL THE MOISTURE IN THE
GROUND AND IN THE AIR. SOME DRYING (THIS WEEKEND) WILL BE NEEDED
BEFORE HIGH TEMPERATURES CAN GET INTO THE UPPER 90S. IN THE SHORT
TERM HIGH TEMPERATURES WILL BE CLOSER TO THE MAV TEMPERATURES.

.LZK...NONE.
