EASTERN OKLAHOMA/NORTHWEST ARKANSAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TULSA OK
1030 AM CDT WED AUG 29 2001

CLOUDS CONTINUE TO DRIFT NORTHWARD FROM TEXAS INTO SOUTHERN
OKLAHOMA.  THIS IS HANDLED WELL IN THE CURRENT WORDING.

PRESENT TEMPERATURE TRENDS ARE ABOUT THE SAME AS TUESDAY.
HOWEVER...THE INCREASING CLOUDS SHOWN IN SATELLITE IMAGERY SUPPORTS
THE CURRENT HIGH TEMP FORECASTS...WHICH ARE A FEW DEGREES COOLER
THAN TUESDAY.  WILL STAY WITH POPS...BUT PUSH BACK THE TIMING IN THE
RDF FOR THE NORTHERN ZONES.  FTW RADAR INDICATES SHOWERS OR
SPRINKLES ALREADY MOVING INTO SOUTHERN OKLAHOMA JUST WEST OF CHOCTAW
COUNTY.  HOWEVER...EXPECT THESE TO WEAKEN THROUGH NOON.  SIGNIFICANT
BREAK IN CLOUDS JUST SOUTH OF THESE SHOWERS JUSTIFIES THE LOW POPS.

FCSTID = 2

.TSA...
AR...NONE.
