EASTERN OKLAHOMA/NORTHWEST ARKANSAS FORECAST DISCUSSION...RETRAN
NATIONAL WEATHER SERVICE TULSA OK
1110 AM CDT MON MAY 17 1999

WILL WAIT TO BETWEEN 1130 AM AND NOON TO UPDATE AS DO NOT KNOW WHEN
OR IF SPC IS GOING TO ISSUE WATCH.  UPDATE WILL TRY TO CURB THE
MORNING AND AFTERNOON WORDING IN CURRENT ZONES.  UPDATE WILL ALSO
INCORPORATE CURRENT RADAR TRENDS.  BAND OF THUNDERSTORMS EXTENDS
FROM NORTHWEST ARKANSAS INTO EAST CENTRAL OKLAHOMA AND CONTINUES TO
PUSH EAST.  THINK THERE IS SOME CHANCE OF REDEVELOPMENT TO THE WEST
AS LOCATION OF THE COLD FRONT IS MUDDLED DUE TO THE THUNDERSTORMS.
WIND SHIFTED TO THE NORTH WITH THE LINE OF STORMS BUT HAS VEERED
AROUND TO THE SOUTHEAST BEHIND THE LINE.

CLOUD COVER ALSO A PROBLEM AS BREAKS OCCURRING TO THE SOUTH OF AND
TO THE WEST OF THE THUNDERSTORMS COMPLEX WILL PROBABLY GO WITH
PARTLY CLOUDY WHERE THUNDERSTORM CHANCES ARE LESS THAN LIKELY.
TEMPERATURES SHOULD REBOUND WITH A LITTLE SUN AND SHOULD ONLY NEED
MINOR TWEEKS.
