DAY 4-8 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0347 AM CDT SAT SEP 22 2012
VALID 251200Z - 301200Z
...DISCUSSION...
LESS CONSISTENCY IS NOTED BETWEEN THE GFS AND ECMWF THIS
FORECAST...WITH A BREAKDOWN IN AGREEMENT BEGINNING DAY 5 /WED. 9-26/
AND THEN INCREASING THROUGH DAY 6 /THU. 9-27/ AND BEYOND.
STILL HOWEVER...BOTH MODELS DEPICT A FAIRLY LOW-AMPLITUDE/WEAK FLOW
FIELD ALOFT OVER THE CONUS...WHICH GENERALLY SUPPORTS LIKELIHOOD FOR
AN ABSENCE OF WIDESPREAD SEVERE WEATHER. THUS...WILL MAINTAIN A
FORECAST HIGHLIGHTING LOW SEVERE POTENTIAL THROUGH THE MEDIUM-RANGE
PERIOD.
