DAY 4-8 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0348 AM CDT WED SEP 02 2009
VALID 051200Z - 101200Z
...POTENTIAL TOO LOW TO DELINEATE A SEVERE THREAT AREA...
A LINGERING MID-LEVEL CIRCULATION IN THE VICINITY OF THE LOWER
MISSOURI/MIDDLE MISSISSIPPI VALLEY MAY IMPEDE LOW-LEVEL MOISTURE
RETURN TO THE NORTHERN PLAINS...AT LEAST THROUGH MUCH OF THE COMING
WEEKEND. THIS IS WHEN THE SPREAD AMONG THE ENSEMBLES AND
VARIABILITY AMONG THE MEDIUM RANGE MODELS IS AT ITS SMALLEST...
CONCERNING A SIGNIFICANT POLAR TROUGH EMANATING FROM THE PACIFIC.
DISCREPANCIES IN THE UPPER FLOW EVOLUTION GROW CONSIDERABLY THROUGH
THE MIDDLE OF NEXT WEEK...BUT IT CURRENTLY SEEMS MOST PROBABLE THAT
THE STRONGER BELT OF WESTERLIES WILL GENERALLY REMAIN NEAR OR NORTH
OF THE CANADIAN/U.S. BORDER. WHILE IT IS STILL POSSIBLE THAT THE
RISK FOR SEVERE STORMS COULD INCREASE ACROSS PARTS OF THE
COUNTRY...RELATIVE TO THE PAST WEEK...THE POTENTIAL FOR AN ORGANIZED
REGIONAL SEVERE WEATHER EVENT APPEARS LOW.
