NATIONAL WEATHER SERVICE TULSA OKLAHOMA
920 PM CDT SUN JUN 29 2003

SCATTERED SHOWERS AND THUNDERSTORMS IN NORTHEAST OKLAHOMA ARE
WEAKENING WITH THE LOSS OF HEATING. NEARLY STATIONARY THUNDERSTORMS
IN THE TULSA AREA EARLIER DROPPED COPIOUS AMOUNTS OF RAINFALL OVER A
FEW SMALL AREAS WHILE PLACES A COUPLE MILES AWAY SAW LITTLE OR NO
RAIN AND EVEN SUNSHINE. WILL LOWER POPS FOR TONIGHT INTO THE 20-30%
RANGE. MADE ONLY MINOR UPWARD ADJUSTMENTS TO TEMPERATURES OVERNIGHT
AND ALSO MADE A FEW CHANGES TO THE SKY COVER GRIDS.

LOOKS LIKE THE RAINS FROM TROPICAL STORM BILL WILL REMAIN TO OUR
EAST AND WOULD NOT BE SURPRISED IF SUBSIDENCE ON THE BACK SIDE OF
THE SYSTEM INHIBITS ANY CONVECTIVE DEVELOPMENT HERE BY TUESDAY. WILL
LET LATER SHIFTS CONSIDER THIS FURTHER.

UPDATE COMING SHORTLY.

THIS OUTLOOK IS FOR NORTHWEST AND WEST CENTRAL ARKANSAS AS WELL AS
MUCH OF EASTERN OKLAHOMA.

OUTFLOW BOUNDARIES FROM LAST NIGHTS THUNDERSTORMS TO THE WEST MAY
SERVE AS A FOCUS FOR NEW THUNDERSTORMS THIS AFTERNOON AND EARLY
EVENING. ADDITIONAL THUNDERSTORMS MAY FORM LATER TONIGHT.

.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY.
CHANCES FOR THUNDERSTORMS WILL CONTINUE INTO THE EARLY PART OF THIS
