AN H500 TROUGH OVER THE WEST COAST WILL FINALLY BE MOVING INLAND MAKING ITS WAY INTO THE NORTHERN PLAINS BY TUESDAY. THIS TROUGH WILL ALLOW SURFACE CANADIAN AIR TO INFILTRATE THE REGION BRINGING A SHALLOW LAYER OF COOL TEMPERATURES THAT MAY SUPPORT AREAS OF FOG AND SOME FREEZING DRIZZLE EARLY TUESDAY. MUCH COOLER FOR TUESDAY AS WE RETURN TO THE UPPER 30S ACROSS THE NORTHWEST AND NORTH CENTRAL WITH HIGHS STILL IN THE MID 50S ACROSS THE SOUTHERN JAMES RIVER VALLEY.
