FIRST ALERT: Night Rain Tonight Transitioning to Accumulating Snow This Weekend
A pattern shift is bringing the first blast of cold air this season to Marquette, Michigan. Multiple weather disturbances are expected, starting with light rain tonight. This rain will move from west to east by tomorrow morning, followed by scattered lake effect rain showers through midday.
Later, the precipitation will change to light lake effect snow showers, primarily along the northwest wind belts. Minor snow accumulations of a quarter to half an inch are possible.
Weekend Forecast and Winter Preview
The first cold air mass of the season arrives this weekend due to a deep trough in the jet stream moving into the Upper Midwest, bringing cold Canadian air. This will be accompanied by an area of low pressure, resulting in the first accumulating snow of the season on Sunday.
The snow will be light lake effect snow in the north and northwest wind belts with a 20-50% chance of accumulation in the north-central Upper Peninsula. A TV6 First Alert Weather Day will be declared for Sunday because of slushy and slippery conditions.
Lake-effect snow showers are expected to continue into Monday.
