Update 9:30AM CST…
As the cold front that produced our overnight snow swings off to the east, the strong pressure gradient associate with the deep low pressure center north of Lake Superior will produce strong northwest winds gusting over 40 miles per hour this morning. The low pressure will continue to pull away to the north and east, loosening the gradient and allowing winds to gradually decrease this afternoon. Cold air will be drawn into the Midwest and western Great Lakes, and our temperatures should be on a steady decline today – dropping through the teens this afternoon into the single digits by this evening.
Winds will become more southerly tonight in advance of the fast-approaching low pressure “Clipper” from the northwest. Temperatures will rise again in advance of this approaching low pressure with snow developing across the region before daybreak Sunday. We are still thinking that a period of accumulating snow – in the 2 to 4-inch range will lay down a fresh blanket of snow before noon. Driving/travel conditions will deteriorate rapidly once the snow sets in early Sunday.
Remnant light snow or freezing drizzle will gradually move east of the area this morning, as a cold front sweeps in from the northwest and temperatures fall into the teens this afternoon and single digits this evening.
Snow Sunday – Wind Chill Watch Monday/Tuesday into Wednesday
A band of snow will precede another “Clipper” low pressure system early later tonight into Sunday forenoon depositing 2 to 4-inches of fresh snow. Frigid Arctic high pressure will follow into our area Sunday night and a Wind Chill Watch has been posted – we will experience strong northwest winds and sub-zero temperatures Monday through Tuesday into Wednesday – calling for dangerous wind chills of -30 to -45-degrees during that period
