FIRST ALERT: Night Rain Tonight to Accumulating Snow This Weekend

A pattern shift brings the first cold air blast of the season to Marquette, Michigan, with active weather expected over the next few days.

Tonight's Weather

Light rain will arrive tonight, moving from west to east by tomorrow morning. Scattered lake-effect rain showers will continue through midday before changing to light lake-effect snow showers in the northwest belts.

Minor snow accumulations of a quarter to half an inch possible.

This Weekend's Forecast

The first significant cold air blast of the season is set for this weekend. A deep trough in the jet stream will bring cold Canadian air into the Upper Midwest along with an area of low pressure. This will cause the first accumulating snow of the season on Sunday, mainly light lake-effect snow across the north and northwest wind belts.

“There’s a 20-50% probability of snow in the north central Upper Peninsula.”

A TV6 First Alert Weather Day is declared for Sunday due to expected slushy and slippery road conditions. Lake-effect snow showers will persist into Monday.
