Milwaukee, WI – The first hard freeze of the season has settled over southeast Wisconsin this Friday morning, coating lawns, windshields, and fields in a silvery frost. The National Weather Service in Milwaukee/Sullivan continues a Freeze Warning until 9 a.m., with temperatures ranging from 26°F to 31°F across much of the region.
For many, this marks the official end of the growing season, stretching from Milwaukee to Madison and south to the Illinois border. Residents are urged to protect any remaining plants and check outdoor plumbing before the chill eases later today.
Skies will turn mostly sunny by late morning, helping temperatures climb into the low 50s Friday afternoon. Winds stay light, giving the day a crisp but calm feel—perfect for cleanup or early holiday prep once frost melts away.
Saturday and Sunday bring a gentle rebound, with highs near the mid-50s and plenty of sun through the weekend. It’s a classic late-October stretch—cold mornings, bright afternoons, and an unmistakable hint of the next season in the air.
While no snow is expected just yet, forecasters note colder air lingering over northern Wisconsin, where a few flakes could fly near the Upper Peninsula early next week. Across the rest of the Midwest, the deep freeze that hit overnight continues to signal winter’s early approach.
With Halloween just a week away, trick-or-treaters might want to plan for chilly, jacket-worthy weather—and maybe the first real taste of November air.
