Milwaukee, WI – A crisp fall chill has swept across Wisconsin this morning, marking a true October turn in the weather. The National Weather Service in Milwaukee/Sullivan warns that patchy frost could develop by early Thursday, especially in areas along and northwest of Highway 151.
According to the National Weather Service, residents in central and southern Wisconsin should expect clear skies, cool mornings, and comfortable afternoons through the end of the week. Drivers should be mindful of reduced visibility early Wednesday due to light fog and dew. Those with gardens or sensitive plants are advised to cover them ahead of the potential frost.
By Thursday, temperatures will climb slightly into the lower 60s with abundant sunshine. Friday and Saturday will stay mostly sunny, reaching highs near 65°F—perfect for pumpkin patch visits and early Halloween decorating. Winds remain calm, averaging 5–10 mph from the north and shifting southeast late in the week.
Looking ahead, Sunday may bring a slight chance of showers, but overall, Wisconsin will enjoy a classic fall stretch—bright, cool, and dry. It’s an ideal time for leaf viewing or a weekend hike across the state’s parks.
Stay tuned for local updates from the Milwaukee/Sullivan office for any changes to frost advisories.
