A low pressure system sweeping out of Canada (referred to as an Alberta Clipper) will bring snow chances across the Great Lakes Monday.  The term ‘clipper’ means this will be a quick moving system, so in terms of accumulative snow, we only really expect a couple inches of snow for these areas.

Snow continues today as the system moves east. An additional inch is expected across the Arrowhead and along the South Shore in NW Wisconsin. Locally higher totals near the lake due to lake effect snow is possible. Snow should end by tonight #mnwx #wiwx pic.twitter.com/GlFzqNNQXX
