First Alert: Night Rain and Weekend Snow Ahead
A noticeable weather shift brings the first cold blast of the season to Marquette, Michigan. Multiple disturbances are on the way, signaling the arrival of winter conditions.
Tonight: Rain Arrives
Light rain will move in tonight, spreading west to east by morning. Scattered lake-effect rain showers will continue through midday before gradually transitioning into light snow, especially along the northwest belts, where around a quarter to half an inch of snow may accumulate.
Weekend Forecast: First Accumulating Snow
Over the weekend, a deep trough in the jet stream will allow cold Canadian air to move into the Upper Midwest. This will bring an area of low pressure responsible for the season’s first measurable snowfall on Sunday. Light lake-effect snow is expected across northern and northwestern wind belts, with a 20–50% chance of accumulation in the north-central Upper Peninsula.
A TV6 First Alert Weather Day will be in effect on Sunday due to slushy and slippery road conditions.
Lake-effect snow showers will likely continue into Monday.

- Today: Mostly cloudy with evening rain. Highs in the low to mid-40s, reaching the upper 40s in the south.
- Friday: Morning rain, turning to scattered showers, later mixing with snow. Highs around 40 in the west, mid to upper 40s elsewhere.
