First Alert: Night Rain and Weekend Snow
A noticeable change in weather patterns brings the first wave of cold air this season to Marquette, Michigan. Meteorologists forecast an active stretch with several disturbances leading to our first blast of winter-like conditions.
Tonight and Friday
Light rain will arrive tonight, moving from west to east by early morning. Scattered lake-effect rain showers are expected through midday before transitioning into light lake-effect snow showers along northwest areas. Snow accumulation may reach up to half an inch.
Weekend Forecast
This weekend, a deep trough in the jet stream will bring colder Canadian air into the Upper Midwest. Low pressure accompanying this system will lead to the season’s first measurable snow on Sunday, mainly affecting northern and northwestern wind belts.
“There’s a 20–50% probability of accumulating snow across the north-central Upper Peninsula.”
Sunday is designated as a TV6 First Alert Weather Day due to slippery and slushy road conditions. Lake-effect snow showers will taper off by Monday.
Daily Outlook
- Today: Increasing clouds with night rain. Highs in the low to mid-40s, upper 40s in the south.
- Friday: Morning rain transitioning to scattered showers and snow later. Highs around 40 in the west, mid to upper 40s elsewhere.
- Saturday: Very cold with occasional flurries.
