EASTERN OKLAHOMA/NORTHWEST ARKANSAS THUNDERSTORM OUTLOOK
NATIONAL WEATHER SERVICE TULSA OK
1240 AM CDT MON JUL 3 1993

THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FOR THE REMAINDER OF
THE NIGHT IN MUCH OF EASTERN OKLAHOMA AND NORTHWEST ARKANSAS.  THE
RISK AREA IS ALONG AND NORTH OF A LINE FROM MCALESTER TO FORT SMITH
TO KINGSTON IN MADISON COUNTY ARKANSAS.

THE ATMOSPHERE OVER THE AREA WILL REMAIN MODERATELY UNSTABLE
THROUGH THE NIGHT AND WITH A SOUTHWESTERLY LOW-LEVEL JET INCREASING
JUST ABOVE THE SURFACE...THE THUNDERSTORMS NEAR THE SOUTHEAST
KANSAS/NORTHEAST OKLAHOMA BORDER WILL LIKELY CONTINUE THROUGH THE
EARLY MORNING HOURS.  THE STORMS HAVE BEEN MOVING ERRATICALLY...BUT
SHOULD SOON BEGIN A SOUTHEAST MOVEMENT THAT WILL TAKE THEM INTO THE
RISK AREA.  THE AMOUNT OF INSTABILITY AND FAVORABLE LOW-LEVEL
INFLOW SUGGESTS A FEW OF THE STORMS WILL HAVE THE POTENTIAL TO
PRODUCE LARGE HAIL AND STRONG WINDS.  IN ADDITION...A FEW
THUNDERSTORMS COULD DEVELOP IN PARTS OF SOUTHEAST OKLAHOMA LATE
TONIGHT IN THE VICINITY OF A WARM FRONT THAT IS SLOWLY LIFTING
NORTH INTO THE AREA.  IF THESE STORMS DEVELOP...THEY TOO WOULD HAVE
THE POTENTIAL TO PRODUCE SEVERE WEATHER.

EMERGENCY MANAGEMENT OFFICIALS AND STORM SPOTTERS ACROSS EASTERN
OKLAHOMA AND NORTHWEST ARKANSAS...SHOULD MONITOR WEATHER CONDITIONS
CLOSELY AND BE READY FOR ACTIVATION IF STORMS APPROACH YOUR AREA.
