AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORMAN OK
331 PM CDT WED SEP 9 2009

.DISCUSSION...
A COLD FRONT... FROM NEAR STILLWATER TO SOUTH OF CHEYENNE
OKLAHOMA... WILL CONTINUE TO MOVE SOUTH THIS EVENING... REACHING
THE RED RIVER REGION LATE TONIGHT. THE FRONT IS THEN EXPECTED TO
LOSE DEFINITION AND WILL HAVE NO FURTHER IMPACT ON OUR FORECAST
AREA... OTHER THAN PERHAPS SOME EXTRA CLOUDS AND A NORTHEAST TO
EAST BREEZE.

ONLY MINOR DAY-TO-DAY CHANGES ARE EXPECTED FROM THIS AFTERNOON
THROUGH FRIDAY. THEN... A STRONGER SYSTEM IS FORECAST TO PUSH
ANOTHER FRONT INTO OUR AREA ON SATURDAY. THE GFS AND ECMWF
ARE IN EXCELLENT AGREEMENT REGARDING THIS STORM SYSTEM... FROM THE
WEEKEND INTO EARLY NEXT WEEK. HOWEVER... EARLIER RUNS OF BOTH MODELS WERE
MUCH MORE AGGRESSIVE WITH THE SOUTHWARD MOTION OF THIS SYSTEM...
WHICH REDUCES CONFIDENCE SIGNIFICANTLY. EVEN SO... THESE LATEST
RUNS REPRESENT THE BEST AVAILABLE FORECAST FOR THAT TIME PERIOD...
AND THE GFS WAS GENERALLY USED WITHOUT MODIFICATION FOR DAYS 4
THROUGH 7.
