EASTERN OKLAHOMA/NORTHWEST ARKANSAS THUNDERSTORM OUTLOOK
NATIONAL WEATHER SERVICE TULSA OK
100 PM CDT SUN JUL 20 1997

NO SEVERE THUNDERSTORMS ARE EXPECTED THIS AFTERNOON OR TONIGHT.

SATELLITE OBSERVATIONS AND THE MORNING WEATHER BALLOON DATA
CONTINUE TO INDICATE A MINIMAL THREAT FOR SEVERE THUNDERSTORMS
ACROSS EASTERN OKLAHOMA AND NORTHWEST ARKANSAS.  MOST OF ANY
SIGNIFICANT UPPER LEVEL SUPPORT WAS IN THE FORM OF A WEAK
DISTURBANCE ACROSS CENTRAL KANSAS.  AT THE SURFACE...OUTFLOW
BOUNDARIES FROM MORNING THUNDERSTORMS OVER SOUTHERN KANSAS HAVE
MOVED SOUTHEASTWARD INTO EASTERN OKLAHOMA.

AS AFTERNOON TEMPERATURES RISE INTO THE LOWER 90S...WIDELY
SCATTERED THUNDERSTORMS WILL FORM ACROSS THE REGION.  ALTHOUGH THE
THUNDERSTORMS ARE EXPECTED TO REMAIN BELOW SEVERE LIMITS...THE
LINGERING OUTFLOW BOUNDARIES COULD FOCUS A FEW ISOLATED STRONG
THUNDERSTORMS WHICH MAY BRIEFLY PRODUCE SMALL HAIL...VERY HEAVY
RAINS...AND GUSTY DOWNBURST WINDS.  THE THUNDERSTORMS SHOULD
DIMINISH WITH THE LOSS OF DAYTIME HEATING AROUND SUNSET.

WITH THE LACK OF SIGNIFICANT UPPER LEVEL SUPPORT AND LITTLE FOCUS
EXPECTED AT THE SURFACE...MOST OF ANY THUNDERSTORMS LATE TONIGHT
AND INTO EARLY MONDAY SHOULD REMAIN NORTH OF EASTERN OKLAHOMA AND
NORTHWEST ARKANSAS.
