EASTERN OKLAHOMA THUNDERSTORM OUTLOOK
NATIONAL WEATHER SERVICE TULSA OK
130 PM CDT THU APR 16 1992

THERE IS A SLIGHT RISK OF OF SEVERE THUNDERSTORMS IN EASTERN OKLAHOMA
THROUGH TONIGHT.  THE THREAT AREA COVERS ALL OF EASTERN OKLAHOMA SOUTH
OF A LINE FROM THE OKLAHOMA BORDER EAST OF MIAMI TO NOWATA TO ENID.
THE GREATEST THREAT FROM SEVERE WEATHER IS LARGE HAIL FOR LATE THIS
AFTERNOON AND EARLY TONIGHT.  HEAVY RAIN IS ALSO A POSSIBILITY.

A WEAK...SLOW MOVING COLD FRONT HAS MOVED INTO NORTHERN OKLAHOMA AND
WILL HELP DEVELOP THE THUNDERSTORMS IN THE MOIST UNSTABLE AIRMASS.
MORNING PRECIPITATION HAS TEMPORARILY STABILIZED THE AIR OVER MOST OF
EASTERN OKLAHOMA. HOWEVER...SUNSHINE THIS AFTERNOON WILL AGAIN RESULT
IN UNSTABLE CONDITIONS TO HELP INITIATE SCATTERED STRONG THUNDERSTORMS
...A FEW POSSIBLY SEVERE.

AN UPPER LEVEL DISTURBANCE MOVING THROUGH OKLAHOMA TODAY WILL WEAKEN
AND MOVE INTO ARKANSAS EARLY THIS EVENING.  THAT COMBINED WITH COOLER
EVENING TEMPERATURES SHOULD ALLOW THUNDERSTORMS TO WEAKEN AND
BECOME MORE SCATTERED AFTER SUNSET.
