FIRST ALERT: Night Rain Tonight to Accumulating Snow This Weekend

A pattern change is bringing the first cold air blast of the season to Marquette, Michigan, along with active weather trends.

Tonight through Friday

Our next system arrives tonight with light rain moving west to east by early morning. Scattered lake-effect rain showers will continue through midday before shifting to light lake-effect snow showers in the northwest areas. Minor snow accumulations of a quarter to half an inch are possible.

Weekend Outlook

This weekend marks the arrival of the first significant cold air blast, caused by a deep trough in the jet stream bringing cold Canadian air into the Upper Midwest. A low-pressure area will move in, triggering the first accumulating snow of the season on Sunday.
