AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LITTLE ROCK AR
400 AM CDT FRI APR 23 2004

.SHORT TERM...TODAY THROUGH SUNDAY
LITTLE CHANGE IN THE WEATHER PATTERN TODAY INTO SATURDAY. FRONT WILL REMAIN
NEARLY STATIONARY ACROSS NORTHERN ARKANSAS WHILE A FEW WEAK SHORT WAVES
MOVE THROUGH THE AREA. AREA OF RAIN AND THUNDERSTORMS ACROSS NORTHERN
ARKANSAS THIS MORNING WILL LIKELY CONTINUE INTO THE MORNING WITH
LOCALLY HEAVY RAIN. THAT SHOULD DIMINISH DURING THE MORNING BUT EXPECT
NEW THUNDERSTORMS TO DEVELOP THIS AFTERNOON AND MOVE INTO THE STATE
WITH THE NORTH MOST FAVORED. WOULD EXPECT THE MOST CONCENTRATED
THUNDERSTORM ACTIVITY AGAIN DURING THE NIGHT WITH SOME SEVERE STORMS
MAINLY LATE IN THE AFTERNOON AND EARLY TONIGHT THEN EVOLVING INTO
HEAVY RAINS AGAIN LATER TONIGHT. DO NOT EXPECT AS MUCH THUNDERSTORM
ACTIVITY IN CENTRAL AND SOUTHERN SECTIONS TO THE SOUTH OF THE FRONT.
WENT WITH CHANCE POPS IN THOSE AREAS AND LIKELY TO CATEGORICAL IN
THE NORTH. WITH THAT AREA HAVING RECEIVED A LOT OF RAIN OVER THE
PAST COUPLE OF DAYS WITH SOME FLASH FLOODING ALREADY...EXTENDED
THE FLASH FLOOD WATCH THROUGH TONIGHT BUT EXCLUDED
SALINE...PULASKI...LONOKE...PRAIRIE...AND MONROE COUNTIES WHO
MISSED OUT ON THE RAIN OVERNIGHT AND DO NOT HAVE BIG CHANCES OF
ADDITIONAL RAIN TODAY AND TONIGHT. WENT CLOSE TO PERSISTENCE ON
TEMP FORECASTS. THE MAIN UPPER LOW WILL START TO COME OUT SATURDAY
AND WILL MOVE OUT FASTER BY SUNDAY WHICH SHOULD DRIVE A COLD
FRONT ACROSS THE AREA AND FINALLY MOVE ALL THE HEAVY RAINS AND
SEVERE WEATHER OUT. WILL CONTINUE HIGHEST POPS IN THE NORTH THROUGH
SATURDAY THEN HAVE HIGH POPS ACROSS THE ENTIRE AREA SATURDAY NIGHT
INTO SUNDAY AS THE FRONT MOVES THROUGH WITH POPS DECREASING FROM
THE WEST BY SUNDAY AFTERNOON. WENT CLOSE TO MAV TEMPS FOR SATURDAY
NIGHT AND SUNDAY.

.LONG TERM...SUNDAY NIGHT THROUGH THURSDAY
GFSLR SHOWS A WEAK REINFORCEMENT OF THE COOL AIR TO TAKE PLACE
MONDAY NIGHT INTO TUESDAY MORNING. THIS FEATURE HAS SLOWED DOWN IN
COMPARISON TO PREVIOUS FORECAST...SO ADJUSTED ITS PASSAGE
ACCORDINGLY. LEFT THE FORECAST DRY SINCE MOISTURE WILL BE LIMITED
WITH THE SURFACE FEATURE. TEMPERATURES WERE IN THE BALL PARK ALREADY.
ADJUSTED WINDS TO FOLLOW THE WEAK FRONT MONDAY NIGHT.
