Chicago, IL – The Midwest may trade crisp autumn air for soggy sidewalks this Halloween. The NOAA Climate Prediction Center outlook for October 25–31, 2025, shows above-normal precipitation across Illinois, Iowa, and Wisconsin, raising the odds of wet weather for trick-or-treaters.
Forecasters say a broad moisture plume moving in from the Plains could bring showers and breezy conditions to parts of the region starting that weekend. Temperatures, however, are expected to stay warmer than average, meaning cold isn’t the issue — rain is. Evening temperatures on Halloween could hover in the 50s or low 60s, making ponchos more useful than parkas.
Families planning to head out should prepare for slippery sidewalks and damp costumes. Experts recommend waterproof footwear, light-reflective rain gear, and clear umbrellas to help children stay visible in darker, wetter conditions. Drivers are also urged to slow down — wet pavement can double stopping distances, and visibility tends to drop sharply in rain.
Meteorologists stress that this forecast could still shift, but the trend toward unsettled weather is strong. Keep an eye on local alerts and radar updates in the days leading up to Halloween. Whether it’s drizzle or a downpour, the key is staying visible, safe, and dry while keeping the spooky spirit alive.
