Extended snow chances as chillier pattern sets in this week

Find NWS alerts in effect HERE.

Cold high pressure over Northwestern Ontario and a low pressure system over Southern Minneapolis work hand in hand to maintain lake effect snow production over Upper Michigan overnight through Tuesday -- moderate to heavy snowfall possible in southeast wind belt locations in the Keweenaw Peninsula and near the Lake Michigan shores.

Snow showers gradually taper off Wednesday as the low pressure system pushes east. But, under a northerly jet stream, a series of clipper systems bring rounds of moderate even heavy snow over Upper Michigan to end the week. High temperatures ranging in the 10s-20s over the weekend.
