A significant pattern shift is bringing the first blast of cold air this season to Marquette, Michigan, and surrounding areas. Multiple weather disturbances will affect the region, starting tonight.
Tonight and Friday Weather

- Friday: Morning rain turning to scattered showers and then scattered snow showers; highs around 40 in the west, mid to upper 40s elsewhere
Weekend Outlook: First Cold Blast and Accumulating Snow
This weekend marks the arrival of cold Canadian air as a deep trough in the jet stream moves into the Upper Midwest, accompanied by an area of low pressure. This setup will bring the first accumulating snow of the season on Sunday, mainly light lake-effect snow across the northern and northwest wind belts.
"There’s a 20-50% probability [of snow] for the north central U.P."
A TV6 First Alert Weather Day will be in effect Sunday due to expected slushy and slippery road conditions. Lake-effect snow showers are forecast to linger into Monday.
- Saturday: Very cold with a few flurries
- Sunday: Light accumulating lake-effect snow
