EASTERN OKLAHOMA/NORTHWEST ARKANSAS THUNDERSTORM OUTLOOK
NATIONAL WEATHER SERVICE TULSA OK
600 AM CDT SAT APR 29 1995

THERE IS A SLIGHT RISK FOR SEVERE THUNDERSTORMS OVER ALL OF EASTERN
OKLAHOMA AND NORTHWEST KANSAS TODAY INTO THIS EVENING.

A COMPLEX OF THUNDERSTORMS WILL CONTINUE TO MOVE SOUTHEAST THROUGH
NORTHEAST AND EASTCENTRAL OKLAHOMA AND INTO NORTHWEST ARKANSAS THIS
MORNING. SEVERE THUNDERSTORMS WILL BE POSSIBLE ON THE LEADING EDGE
OF THIS COMPLEX WITH AN EXTENDED PERIOD OF HEAVY RAIN IN ITS WAKE.
SO EVEN WITH THE PASSAGE OF THE STRONG TO SEVERE THUNDERSTORMS...
THERE WILL BE A THREAT FOR FLASH FLOODING DURING THE MORNING.

THE THUNDERSTORMS MAY CONTINUE TO DEVELOP SOUTHWARD INTO SOUTHEAST
OKLAHOMA ALSO DURING THE MORNING AS MOISTURE CONTINUES TO FEED INTO
THE SYSTEM FROM THE SOUTH. A FEW OF THESE STORMS MAY ALSO BE SEVERE
WITH STRONG WINDS AND LARGE HAIL.

THERE SHOULD BE A BREAK IN THE SHOWERS AND THUNDERSTORMS OVER
EASTERN OKLAHOMA AND NORTHWEST ARKANSAS BY MIDDAY. A LOW PRESSURE
SYSTEM WILL DROP SOUTHEAST INTO NORTH TEXAS DURING THE DAY WITH A
WARM FRONT EXTENDING INTO SOUTHEAST OKLAHOMA. MOISTURE WILL
CONTINUE TO INCREASE ALONG AND SOUTH OF THIS FRONT AND FURTHER
DESTABILIZE THE ATMOSPHERE THIS AFTERNOON. CONVERGENCE NEAR THE
FRONT MAY BE ENOUGH TO GENERATE SCATTERED AFTERNOON THUNDERSTORMS.
IF THESE STORMS DEVELOP THEY COULD POSSIBLY BECOME SEVERE WITH
LARGE HAIL AND STRONG WINDS. THESE STORMS SHOULD REMAIN SOUTH OF A
LINE FROM FORT SMITH TO MCALESTER AND COULD LAST INTO THE EVENING
HOURS BEFORE DISSIPATING.

NORTH OF THE WARM FRONT IN NORTHEAST OKLAHOMA AND NORTHWEST
ARKANSAS...SEVERE THUNDERSTORMS ARE NOT EXPECTED THIS AFTERNOON OR
THIS EVENING. THERE IS A SLIGHT CHANCE FOR SHOWER OR THUNDERSTORM
REDEVELOPMENT IN THIS AREA BUT THIS MORNINGS ACTIVITY SHOULD HELP
STABILIZE THE ATMOSPHERE.

EMERGENCY MANAGEMENT AGENCIES AND STORM SPOTTER GROUPS IN THE RISK
AREA SHOULD BE PREPARED FOR ACTIVATION THIS MORNING. THOSE SOUTH OF
A FORT SMITH TO MCALESTER LINE SHOULD ALSO BE PREPARED FOR
ACTIVATION THIS AFTERNOON AND THIS EVENING. AN UPDATED OUTLOOK WILL
BE ISSUED AROUND 1PM.
