A pattern change brings the first cold air blast of the season to Marquette, Michigan. Expect an active weather trend with multiple disturbances ahead.
A weather system arrives tonight, bringing light rain as it moves from west to east by tomorrow morning. Scattered lake effect rain showers will continue through midday before transitioning to light lake effect snow showers in the northwest.
The first significant cold air surge arrives this weekend due to a deep jet stream trough moving into the Upper Midwest, bringing cold Canadian air and a low-pressure area.
This setup will cause the first accumulating snow of the season on Sunday, mainly light lake effect snow across the north and northwest wind belts.
There is a 20-50% chance of snow in the north central Upper Peninsula. A TV6 First Alert Weather Day is in effect for Sunday due to potentially slippery and slushy conditions. Lake-effect snow showers will continue into Monday.
