EASTERN OKLAHOMA THUNDERSTORM OUTLOOK
NATIONAL WEATHER SERVICE TULSA OK
1230 PM CDT FRI JUN 19 1992

THERE IS A HIGH RISK OF SEVERE THUNDERSTORMS THROUGH TONIGHT OVER
ALL OF EASTERN OKLAHOMA.

STRONG AND SEVERE THUNDERSTORMS REDEVELOPED IN SOUTH CENTRAL AND
SOUTHEAST KANSAS LATE THIS MORNING.  NUMEROUS TORNADOES HAVE BEEN
REPORTED WITH THE STORMS IN KANSAS. VERY UNSTABLE AIR RESIDES OVER
EASTERN OKLAHOMA AND A CONTINUALLY STRENGTHENING WIND FIELD WILL HELP
THE THUNDERSTORM TO MAINTAIN THEIR INTENSITY AS THEY MOVE SOUTHEAST.
THE HIGHEST THREAT OF SEVERE WEATHER IS IN NORTHEAST OKLAHOMA EARLY
THIS AFTERNOON AND ALL OF EASTERN OKLAHOMA WILL BE THREATENED LATE
THIS AFTERNOON AND EVENING.  LARGE HAIL AND DAMAGING WINDS ARE THE
MAIN THREAT...BUT TORNADOES ARE A DEFINITE POSSIBILITY.
+
DAYTIME HEATING WILL ALLOW AFTERNOON TEMPERATURES TO CLIMB INTO THE
LOWER 90S. THESE TEMPERATURES COMBINED WITH DEWPOINT TEMPERATURES AROUND
70 WILL MAKE FOR AN EXTREMELY UNSTABLE ATMOSPHERE. SCATTERED
THUNDERSTORMS WILL DEVELOP THIS AFTERNOON NEAR BOUNDARIES LEFT OVER
FROM THIS MORNINGS THUNDERSTORMS. THE AFTERNOON THUNDERSTORMS WILL BE
MOST INTENSE IN THOSE AREAS THAT DO NOT RECEIVE SIGNIFICANT RAINS THIS
MORNING.  IN NORTHEAST OKLAHOMA THE AREA BETWEEN PONCA CITY AND
BARTLESVILLE IS UNDER IMPENDING THREAT OF SEEING SEVERE WEATHER BY
100 PM CDT.

EMERGENCY MANAGEMENT OFFICIALS AND STORMS SPOTTERS IN NORTHEAST OKLAHOMA
