Less chilly, but more wind plus snow through Saturday
Wind gusts over 30 mph as a clipper system brings widespread snow through Saturday morning.
High pressure and benign, seasonal weather conditions end Friday night in Upper Michigan as a Canadian Prairies system brings in widespread snow overnight through Saturday morning. Lake effect snow develops over the northwest wind belts Saturday afternoon as the system exits the region. Snowfall amounts Saturday range from 1″-3″, with 4″ or more in the Keweenaw and Eastern U.P. Occasionally heavy snow coupled with strong wind can drastically reduce visibility (blowing snow) in addition to slick road conditions.

Temperatures trend mainly below seasonal this forecast period, driven by a northwesterly jet stream plummeting from the Interior Plains of Canada -- a conduit of cold that steers clipper systems towards Upper Michigan and keeps snow chances at play the next seven days.
