SECTIONS OF THE AREA. IN ADDITION...THIS FLOW AND ADEQUATE
MOISTURE WILL FAVOR SOME LIGHT SNOW ACROSS THE NORTHWEST MTS. THEN
THE EMPHASIS SHIFTS TO A DECENT TROUGH PUSHING INTO THE PACIFIC
NORTHWEST ON TUESDAY. MEDIUM RANGE MODELS HAVE SLOWED THIS TROUGH
A BIT FROM YESTERDAYS 00Z RUNS AND HAVE LOWERED POPS FOR
