...DISCUSSION...

DOMINANT MIDLEVEL ANTICYCLONE INITIALLY CENTERED OVER THE ERN THIRD
OF THE NATION WILL RETROGRADE WWD THROUGH THE EXTENDED
PERIOD...BRACKETED BY TROUGHING OVER THE ERN PACIFIC/WEST COAST AND
INTENSIFYING TROUGH ACROSS ERN CANADA. WITHIN THIS BROADER-SCALE
FLOW REGIME...MEDIUM-RANGE MODEL GUIDANCE REMAINS RELATIVELY
CONSISTENT IN SUGGESTING A SHORT WAVE TROUGH WILL LIFT NEWD THROUGH
THE NRN HIGH PLAINS ON D4 WITH AN ASSOCIATED THREAT FOR SEVERE
STORMS OVER ERN MT...THE DAKOTAS INTO THE UPPER MS VALLEY. THIS
MIDLEVEL SYSTEM WILL CREST MEAN RIDGE AXIS ACROSS S-CNTRL CANADA ON
D5/D6 BEFORE DIVING SEWD THROUGH THE NERN U.S. ON D7. SEVERE STORMS
WILL BE POSSIBLE FROM THE GREAT LAKES REGION INTO THE NERN STATES
DURING THIS TIME PERIOD...HOWEVER UNCERTAINTIES IN MORE SPECIFIC
TIMING/LOCATION AND DEGREE OF SEVERITY PRECLUDE DELINEATION OF A
SEVERE WEATHER AREA.
