.DISCUSSION...
LINGERING MOISTURE AND VARIOUS WEAK DISTURBANCES IN THE ATMOSPHERE
WILL RESULT IN CONTINUING LOW CHANCES FOR RAIN THROUGH THE REST OF
THE WORK WEEK. TEMPERATURES WILL REMAIN FAIRLY WARM FOR MID-
SEPTEMBER.

THE NEXT MAJOR EVENT APPEARS TO BE A STORM SYSTEM DUE TO ARRIVE
THIS WEEKEND. MODELS ARE IN REASONABLY GOOD AGREEMENT THAT
MOISTURE WILL INCREASE FURTHER...POSSIBLY ENHANCED BY MOISTURE
ASSOCIATED WITH FORMER HURRICANE ODILE...AND THAT THE STORM SYSTEM
WILL BEGIN ITS MAIN EFFECTS LATE FRIDAY INTO SATURDAY.

THE MODELS DO NOT AGREE...HOWEVER...ON THE EXIT STRATEGY OF THE
STORM. THE ECMWF KEEPS THE SYSTEM OVER OKLAHOMA LONG ENOUGH TO
GENERATE HUGE AMOUNTS OF RAINFALL...WHILE THE GFS IS QUICKER TO
ADVANCE THE STORM...RESULTING IN LESS EXTREME RAINFALL AMOUNTS.
OUR FORECAST IS CLOSER TO THE GFS...AND WE CERTAINLY HOPE THIS IS
THE MORE CORRECT OUTCOME...SINCE THE ECMWF SCENARIO WOULD LIKELY
RESULT IN SERIOUS FLOODING.
