HAZARDOUS WEATHER OUTLOOK
Issue Date: 524 PM CST TUE DEC 22 2009
Expiration: 500 AM CST WED DEC 23 2009
THIS HAZARDOUS WEATHER OUTLOOK IS FOR A LARGE PART OF ARKANSAS.
.DAY ONE...TONIGHT
ISOLATED TO SCATTERED SHOWERS WILL CONTINUE ACROSS ARKANSAS THIS
EVENING AND OVERNIGHT. THE RAINFALL WILL BECOME MORE WIDESPREAD AS A
POWERFUL STORM SYSTEM DEVELOPS IN THE SOUTHERN PLAINS AND MOVES
TOWARD THE MID SOUTH. A FEW THUNDERSTORMS ARE EXPECTED AFTER
MIDNIGHT TONIGHT.
.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY
THE STORM SYSTEM WILL CONTINUE ADVANCING TOWARD ARKANSAS ON
WEDNESDAY. COPIOUS AMOUNTS OF GULF MOISTURE WILL MOVE UP OVER THE
REGION. SHOWERS AND THUNDERSTORMS WILL BE WIDESPREAD BY WEDNESDAY
MORNING.
ON WEDNESDAY EVENING AND THURSDAY MORNING...A LINE OF SHOWERS AND
THUNDERSTORMS IS EXPECTED TO MOVE THROUGH THE AREA...ALONG AND AHEAD
OF A STRONG COLD FRONT. SOME OF THE STORMS COULD BECOME SEVERE. ANY
SEVERE THUNDERSTORMS WILL BE CAPABLE OF PRODUCING HAIL DUE TO COLD
AIR ALOFT. ALSO...THERE WILL BE A LARGE AMOUNT OF WIND ENERGY WITH
THE SYSTEM...WHICH WILL INCREASE THE THREAT FOR DAMAGING STRAIGHT-
LINE WINDS...AND THE POSSIBILITY OF TORNADO DEVELOPMENT.
STRONGER STORMS WILL ALSO BE CAPABLE OF PRODUCING LOCALLY HEAVY
RAINFALL...WITH PORTIONS OF ARKANSAS RECEIVING TWO TO FOUR INCHES OF
RAIN...WITH HIGHER AMOUNTS POSSIBLE. THIS WILL INCREASE THE
POSSIBILITY OF FLASH FLOODING. WITH THE AMOUNT OF RAIN EXPECTED
FALLING ON LARGELY DORMANT VEGETATION...A FLASH FLOOD WATCH IS IN
EFFECT FOR WEDNESDAY NIGHT THROUGH NOON THURSDAY.
THE STRENGTH OF THIS SYSTEM AND CLOSE PROXIMITY TO HIGH PRESSURE TO
THE EAST AND WEST OF IT WILL ALLOW FOR GUSTY WINDS WEDNESDAY NIGHT
AND THURSDAY. WINDS OF 10 TO 20 MPH...WITH GUSTS AS HIGH AS 30 MPH
WILL BE COMMON ACROSS THE AREA.
AS THE FRONT MOVES EAST AND NORTHEAST OF THE AREA ON THURSDAY
AFTERNOON AND EVENING...CONSIDERABLY COLDER AIR WILL SWEEP INTO THE
STATE. AS THE COLDER AIR MIXES IN...SOME SNOW WILL BE POSSIBLE
THURSDAY NIGHT THROUGH EARLY CHRISTMAS DAY ACROSS THE NORTH.
SNOWFALL AMOUNTS DO NOT APPEAR TO BE SIGNIFICANT AT THIS TIME...BUT
SOME AREAS COULD SEE A DUSTING OF SNOW...ESPECIALLY CLOSE TO THE
MISSOURI BORDER. OVER CENTRAL ARKANSAS...THERE WILL MOSTLY BE A MIX
OF RAIN AND FLURRIES BEFORE PRECIPITATION COMES TO AN END ON
CHRISTMAS MORNING.
.SPOTTER INFORMATION STATEMENT...
SPOTTER ACTIVATION MAY BE NEEDED WEDNESDAY NIGHT THROUGH EARLY
THURSDAY.
