A fast moving system pushing through the Upper Midwest and Great Lakes will bring some light snow to these regions Monday into Tuesday. Across the Northern Rockies, heavy snow will develop late Monday and continue through Wednesday evening as an upper level low persists and remains nearly stationary over the region.

US Hazards

Region 1
An Alberta Clipper will make its way southeastward across the Upper Midwest and into the Great Lakes Monday and Tuesday. As this system makes its way eastward, light to moderate snowfall will overspread the region and become heavier during the day. General snowfall amounts of 3-5 inches is forecast with isolated higher amounts in excess of 6 inches. Snowfall will begin to lighten and end across the area from northwest to southeast late Tuesday morning, though some light snow may continue into the evening.
