EASTERN OKLAHOMA THUNDERSTORM OUTLOOK
NATIONAL WEATHER SERVICE TULSA OK
1245 PM CDT SUN MAY 9 1993

THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS LATE THIS
AFTERNOON AND EVENING OVER PARTS OF SOUTHEAST OKLAHOMA. THIS
SLIGHT RISK AREA IS SOUTH OF A LINE FROM SALLISAW TO MCALESTER.

ELSEWHERE ACROSS EASTERN OKLAHOMA SHOWERS AND THUNDERSTORMS WILL
LIKELY REDEVELOP BY EVENING...BUT HEAVY RAINS WILL BE THE MAIN
THREAT. THE SERIOUS FLOODING PROBLEM IN EASTERN OKLAHOMA WILL
ONLY BE AGGRAVATED BY ADDITIONAL RAINS THROUGH TONIGHT INTO
MONDAY MORNING.

AT MIDDAY...A STALLED FRONT STILL EXTENDED FROM NEAR TULSA TO
NEAR ARDMORE WITH LOW PRESSURE ALONG THE FRONT IN NORTH TEXAS.
MORNING SHOWERS AND THUNDERSTORMS HAVE STABILIZED THE ATMOSPHERE
IN NORTHEAST OKLAHOMA AND TEMPERATURES WILL STAY IN THE 60S THERE
THIS AFTERNOON. IN SOUTHEAST OKLAHOMA...IT WILL STAY HUMID THIS
AFTERNOON WITH TEMPERATURES IN THE 70S. THUNDERSTORMS WILL LIKELY
REDEVELOP AHEAD OF ANOTHER UPPER LEVEL DISTURBANCE THAT WILL MOVE
INTO SOUTHEAST OKLAHOMA LATE THIS AFTERNOON. THE THUNDERSTORMS
WILL SPREAD NORTHEAST INTO EAST CENTRAL AND NORTHEAST OKLAHOMA BY
EVENING. THE MORE UNSTABLE AIR IN SOUTHEAST OKLAHOMA MAY ALLOW
SOME OF THE STORMS TO BECOME SEVERE WITH HAIL AND DAMAGING WINDS
POSSIBLE. A FEW ISOLATED TORNADOES ARE ALSO POSSIBLE.

THE RAINS OVER THE PAST DAY OR SO OVER EASTERN OKLAHOMA HAVE
GREATLY BURDENED ALL CREEKS...STREAMS AND RIVERS IN THE AREA WITH
MANY IN FLOOD. THE ADDITIONAL RAINS TONIGHT WILL CAUSE WIDESPREAD
FLOODING PROBLEMS OVER MUCH OF EASTERN OKLAHOMA.
