GREEN BAY, Wis. – A damp, gray start across northeast Wisconsin will give way to crisp, starry skies and a true taste of late fall by week’s end. Showers will fade, winds will settle, and frost will soon spread across lawns and fields from Green Bay to Appleton — the first widespread sign that winter isn’t far behind.
According to the National Weather Service in Green Bay, light rain will taper Wednesday with a steady northwest breeze gusting up to 25 mph. Skies will clear by Thursday, allowing temperatures to fall into the lower 30s both Thursday night and Friday morning. Frost will be widespread across inland areas, while sheltered valleys north of Highway 29 could dip to freezing. The region’s first hard frost may even form near Shawano and Oconto, where calm air and dry ground combine for ideal cooling.
Residents are urged to cover tender plants, drain outdoor hoses, and bring in porch decor that could crack or fade in the chill. Commuters should expect frosty windshields early Friday and slick patches on bridges and rural roads. The shift marks the region’s transition into its early winter rhythm — that brisk, smoky-air stretch when each morning feels colder than the last.
After the frost, sunshine dominates Friday through Sunday with mild afternoons and crisp nights — perfect for raking leaves, late football games, or early Halloween decorating. To be fair, no snow is expected in Green Bay yet, but flakes have already been spotted in the Upper Peninsula. For many in northeast Wisconsin, it’s less a matter of “if” than “when.”
