NEXT SYSTEM IS QUICKLY PROGRESSING ACROSS CANDIAN ROCKIES AND WILL BE DROPPING INTO DAKOTA BY THIS EVENING AND INTO WESTERN GREAT LAKES BY 48 HRS. THIS CLIPPER WILL PUSH COLD FRONT THROUGH CWA OVERNIGHT ALONG WITH PLENTY OF MID LEVEL MOISTURE. PCPN NOT REALLY OF A CONCERN AS LIFT THROUGH DENDRITIC LAYER IS MINIMAL AND FAIRLY DRY LOWER LAYERS WILL BE HARD TO SATURATE. LOOKING AT MODEL BUFKIT DATA MOST LIKELY OUTCOME WITH THE STRONG CAA WILL BE FLURRIES ALONG WITH INCREASING WINDS. ONLY PLACE MEASUREABLE PCPN MAY BE POSSIBLE IS DOWNSTREAM FROM HILLS IN NW FLOW COUPLING WITH UPPER JET AXIS ALOFT AND LOW POPS RETAINED. MAIN CONCERN LOOKS TO BE WINDY CONDITIONS SETTING UP ACROSS AT LEAST NORTHEAST HALF OF CWA WEDNESDAY AROUND SUNRISE.
