AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LITTLE ROCK AR
300 PM CDT WED OCT 24 2001

LEFT OVER WEATHER WILL BE THE FIRST CONCERN. MOST OF THE
PRECIPITATION WILL BE OVER BY 00Z THU...BUT I WILL NEED TO HAVE SOME
MENTION OF IT EARLY. COOLING DOES NOT SHOW UP AS STRONG AS GUIDANCE
HAD WITH EARLIER PACKAGES. STRONG GRADIENT WILL KEEP THE AIR MIXED
SO IT WILL COUNTERACT A BIT THE COLD ADVECTION. WINDY TONIGHT WITH
CAUTION ADVISED ON LAKES FOR THE ENTIRE FORECAST AREA. NORTHWEST
ZONES WILL BE CLEAR RIGHT OFF THE BAT WITH THE REMAINING ZONES
CLEARING DURING THE NIGHT. DRY AIR WILL KEEP SUNNY/CLEAR SKIES FROM
THURSDAY ON INTO THE EXTENDED. AVN SURFACE WINDS SHOW GRADIENT
STAYING UP MOST OF THE TIME DURING THE SHORT RANGE FORECAST...SO
TOOK OUT THE MENTION OF FREEZE OR FROST SINCE TEMPS WILL STAY UP
ALONG WITH THE WINDS. IN THE EXTENDED...KEPT THE CHANCE OF FROST FOR
SUNDAY ACROSS THE NORTH ONLY. 32

.LIT...NONE.

SEVERE WEATHER OUTLOOK
NATIONAL WEATHER SERVICE LITTLE ROCK AR
403 PM CDT WED OCT 24 2001

...SLIGHT RISK OF SEVERE WEATHER IN EASTERN ARKANSAS INTO EARLY
EVENING...

THERE IS A SLIGHT RISK OF SEVERE WEATHER IN MUCH OF EASTERN
ARKANSAS THROUGH EARLY THIS EVENING.

STRONG THUNDERSTORMS AHEAD OF A COLD FRONT HAVE BEEN PRODUCING VERY
STRONG WINDS. THESE STORMS DEVELOPED JUST AHEAD OF A COLD FRONT.
THE FRONT WILL MOVE OUT OF ARKANSAS THIS EVENING...TAKING THE
THUNDERSTORMS WITH IT.

DUE TO STRONG WINDS ALOFT...DAMAGING WINDS WILL CONTINUE TO BE THE
GREATEST SEVERE WEATHER THREAT...BUT THERE COULD BE SOME LARGE HAIL
AS WELL. AN ISOLATED TORNADO CANNOT BE RULED OUT.

STORM SPOTTERS...AMATEUR RADIO OPERATORS...AND EMERGENCY MANAGERS
WILL BE NEEDED UNTIL THE THUNDERSTORMS MOVE EAST OF ARKANSAS THIS
EVENING.
