...DISCUSSION...
MINOR DIFFERENCES BETWEEN MEDIUM-RANGE MODEL SOLUTIONS ARE EVIDENT
AT THE START OF THE PERIOD -- MAINLY WITH EVOLUTION OF UPPER
TROUGHING OVER WRN AND CENTRAL CANADA...AND THE ASSOCIATED EFFECT ON
CONVECTIVE POTENTIAL OVER THE N CENTRAL AND EVENTUALLY THE NERN
CONUS. THE GFS TENDS TO KEEP TWO SEPARATE UPPER LOW CENTERS...WHICH
PROGRESS STEADILY EWD. MEANWHILE...THE ECMWF WEAKENS THE ERN-MOST
LOW...SOMEWHAT MERGING THE TWO INTO ONE STRONGER LOW.
IN EITHER CASE HOWEVER...WHILE SOME SEVERE THREAT COULD BE POSSIBLE
FROM THE CENTRAL U.S. EWD ACROSS THE GREAT LAKES/OH VALLEY REGION
THROUGH DAYS 6-7 /SEPT 5-6/...WIDESPREAD/SUBSTANTIAL SEVERE
POTENTIAL APPEARS UNLIKELY.
