EASTERN OKLAHOMA/NORTHWEST ARKANSAS HAZARDOUS WEATHER OUTLOOK
NATIONAL WEATHER SERVICE TULSA OK
535 PM CST FRI NOV 23 2001

...UPDATE...

AN OUTBREAK OF SEVERE THUNDERSTORMS IS STILL EXPECTED ACROSS FAR
EASTERN OKLAHOMA AND NORTHWEST ARKANSAS THIS EVENING AND TONIGHT.

A POWERFUL STORM SYSTEM WAS MOVING SLOWLY ACROSS THE CENTRAL
PLAINS.  THIS SYSTEM SLOWED ITS PROGRESS TODAY AS IT CONTINUED TO
STRENGTHEN.  HOWEVER IT WILL ACCELERATE EAST TONIGHT AS STRONG
JET STREAM WINDS PUNCH INTO THE CENTRAL U.S.

SCATTERED THUNDERSTORMS WILL DEVELOP IN EASTERN OKLAHOMA AND
EXTREME WESTERN ARKANSAS BETWEEN 6PM AND 8PM AND QUICKLY BECOME
SEVERE. THE STORMS WILL FORM A LINE AND RACE ACROSS NORTHWEST
ARKANSAS...WITH THE THREAT DIMINISHING AFTER 2AM AS THE LINE EXITS
THE AREA.

VERY STRONG WIND FIELDS AND INCREASING INSTABILITY WILL PROMOTE STORM
ROTATION AND SUPERCELLS. THERE WILL BE A THREAT FOR TORNADOES AND
VERY LARGE HAIL FOR THE FIRST SEVERAL HOURS OF THE EVENT...WITH THE
THREAT TRANSITIONING TO DAMAGING WINDS AS THE STORMS FORM INTO A
LINE.

GIVEN THE FAST WINDS ALOFT THERE IS THE POTENTIAL FOR
STRUCTURAL DAMAGE IN THE MOST SEVERE STORMS.  PERSONS IN EASTERN
OKLAHOMA AND NORTHWEST ARKANSAS SHOULD PAY CLOSE ATTENTION TO THE
WEATHER TONIGHT AND BE READY TO ACT.

STAY TUNED TO THIS STATION FOR FURTHER INFORMATION FROM THE NATIONAL
WEATHER SERVICE.
