SPECIAL WEATHER STATEMENT

1109 AM CST THU JAN 21 1999

...MAJOR SEVERE WEATHER OUTBREAK POSSIBLE THIS AFTERNOON AND TONIGHT...

STRONG UPPER LEVEL WINDS...INCREASING MOISTURE...AND A STRONG LOW
PRESSURE SYSTEM AT THE SURFACE AND ALOFT ARE COMBINING TO CAUSE A HIGH
RISK OF SEVERE WEATHER IN ARKANSAS LATER THIS AFTERNOON AND TONIGHT.

DUE TO THE WIND PATTERN ALOFT AND THE STRENGTH OF THIS WEATHER
SYSTEM...TORNADOES ARE ALSO A STRONG POSSIBILITY. THE GREATEST THREAT OF
TORNADOES WILL BE OVER CENTRAL...SOUTHERN AND EASTERN ARKANSAS. SEVERE
THUNDERSTORMS MAY ALSO OCCUR OVER NORTH ARKANSAS.

THE MAIN INHIBITING FACTOR RIGHT NOW SEEMS TO BE A WARM LAYER OF AIR
AROUND 10,000 FEET UP IN THE ATMOSPHERE. THIS SERVES TO CAP ANY
THUNDERSTORM DEVELOPMENT. HOWEVER...WITH A STRONG COLD FRONT
AND VERY UNSTABLE AIR APPROACHING FROM NORTHEAST TEXAS...THIS CAP WILL
LIKELY BREAK LATER THIS AFTERNOON.

PERSONS IN ARKANSAS SHOULD ABREAST OF THE WEATHER THIS AFTERNOON AND
EVENING IN CASE SEVERE THUNDERSTORM OR TORNADO WATCHES OR WARNINGS ARE
ISSUED. BE PREPARED TO TAKE COVER QUICKLY IF SEVERE WEATHER IS SEEN OR A
WARNING IS ISSUED.

...TORNADO WATCH FOR MOST OF ARKANSAS UNTIL 9PM...

AS OF EARLY THIS AFTERNOON...GULF MOISTURE CONTINUED TO INCREASE ACROSS
ARKANSAS. TEMPERATURES WERE INTO THE 70S IN MOST AREAS AND NEARING 80
DEGREES IN SOUTHERN SECTIONS OF THE STATE. MORE SPECIFICALLY...THERE
WAS PLENTY OF ENERGY AVAILABLE FOR THUNDERSTORMS TO DEVELOP ACROSS
ARKANSAS.

A STORM SYSTEM WILL MOVE OVER THE REGION THIS AFTERNOON AND TONIGHT...
BRINGING COLD AIR ALOFT. THIS WILL TEND TO DESTABILIZE THE ATMOSPHERE
FURTHER...WITH SCATTERED TO NUMEROUS SEVERE THUNDERSTORMS DEVELOPING.

IN ADDITION...THERE WAS SOME WIND SHEAR PRESENT THIS AFTERNOON. WITH
THE WIND TURNING WITH HEIGHT...THIS WILL CAUSE SOME OF THE STORMS
TO ROTATE WITH TORNADOES DEVELOPING.

A TORNADO WATCH HAS BEEN POSTED FOR MOST OF ARKANSAS UNTIL 9PM THIS
EVENING. THE WATCH INCLUDES AREAS EAST OF YELLVILLE...RUSSELLVILLE
AND DEQUEEN.

TORNADOES...LARGE HAIL...AND DAMAGING WINDS ARE ALL POSSIBLE IN
