Record high temperatures are expected in the Chicago area on Tuesday as the unseasonably warm weather continues into Wednesday – but trick-or-treaters may have to join forces on Thursday.

The expected high temperature for Tuesday is 81 or 82 degrees, which would break the 1999 record high of 78 degrees for Oct. 29, according to Lee Carlaw, a meteorologist with the National Weather Service.

Temperatures are not expected to drop much Tuesday night, and Wednesday will be just as warm, although the record of 85 degrees set in 1950 may not be broken, Carlaw said.

Wind gusts of 65 to 70 km/h are expected during the unseasonably warm stretch, and showers are expected Wednesday night into Thursday morning with a cold front.

“The good news is that any rain and storms that come with the front Wednesday night and Thursday morning should clear out here Thursday afternoon and into the evening,” Carlaw said. “So we have dry conditions for basically the peak time for trick-or-treating.”

Highs on Halloween are expected to be around 60 degrees, with temperatures dropping into the 40s in the evening hours, according to the weather service.

“Obviously temperatures are different for everyone, but if that’s cold for some people, then obviously plan for some kind of bundling up,” Carlaw said. “It will be noticeably cooler than in recent days.”

Carlaw said warmer than normal temperatures are not unusual this time of year, and he expects something similar to happen next week.

“This is the time of year when we see rapid changes from day to day and week to week,” Carlaw said. “This is usually a time when we can see quite active patterns and strong storm systems.”
