Green Bay, WI – The Badger State wakes under a crisp, frozen stillness this Friday morning as frost coats fields, cars, and rooftops across northeast Wisconsin. A Freeze Warning remains in effect until 9 a.m. CDT, with temperatures dipping as low as 29°F — enough to end the growing season for much of the region.
According to the National Weather Service in Green Bay, the warning covers Outagamie, Brown, Manitowoc, Winnebago, Calumet, and Kewaunee Counties, where calm winds and clear skies allowed heat to escape rapidly overnight. The cold could harm sensitive plants and potentially damage exposed pipes or outdoor plumbing. Residents are urged to protect tender vegetation and disconnect hoses before the next frost cycle.
By late morning, sunshine takes over as highs climb near 51°F. Friday marks the pivot from hard freeze to mild recovery, setting up a pleasant weekend. Saturday will bring clouds but no major impact, with highs near 53°F, while Sunday looks sunnier and warmer — around 57°F, ideal for outdoor cleanup or early Halloween decorating.
Looking ahead, Monday stays mostly sunny before a few weak disturbances bring light rain chances midweek. Temperatures remain steady in the mid-50s, keeping conditions seasonable for late October.
While northern Wisconsin may catch its first snowflakes in the coming week, Green Bay and nearby towns will stick to cold rain and crisp nights. Still, the chill this morning serves as a clear signal — winter’s first touch has arrived in Wisconsin.
