...DISCUSSION...
WEAK CENTRAL U.S. TROUGH IS FORECAST TO PROGRESS EWD WITH TIME...AND
IS FORECAST TO PHASE WITH A SECOND TROUGH MOVING ESEWD ACROSS
CENTRAL AND ERN CANADA/THE UPPER GREAT LAKES REGION. THE ECMWF AND
GFS HANDLE THE PHASING/EVOLUTION OF THIS TROUGH DIFFERENTLY...BUT
BOTH AGREE THAT A WEAK COLD FRONT WILL SHIFT EWD ACROSS THE ERN HALF
OF THE CONUS THROUGH THE PERIOD.
ATTM...IT APPEARS THAT MID-LEVEL CYCLONIC FLOW AROUND THE UPPER
TROUGH SHOULD REMAIN MODEST /GENERALLY LESS THAN 30 KT/. THIS
COMBINED WITH THE FACT THAT THE STRONGEST OF THE FLOW APPEARS TO
REMAIN TO THE COOL SIDE OF THE FRONT SUGGESTS THAT THE SEVERE
POTENTIAL WITH THIS SYSTEM SHOULD REMAIN SUFFICIENTLY-LIMITED TO
PRECLUDE INTRODUCTION OF ANY THREAT AREAS THIS FORECAST.
