A strong low pressure system slowly moves east over the Straits of Mackinac Monday, its pinwheel of moderate-heavy bands of snow and rain continuing to spin across Upper Michigan -- all driven by gale-force winds mainly from the north. Whiteout, blizzard conditions likely tonight in the Western U.P., and scattered rain and snow over the eastern. Overnight is a full transition to snow across Upper Michigan -- but the influx of dry air begins the tapering off process west into Tuesday morning. Additional snow amounts, this after 7″+ snow reports in the Copper Country Monday morning, can range from 1-8″ along the northwest wind belts near Lake Superior. Gradual sunshine Tuesday in the U.P. for a brief reprieve from precipitation before picking up again later Wednesday.

The snow threat lessens for the week, but flooding concerns remain with a trend of above freezing daytime temperatures plus rain chances moving in on Thursday.
