The Chicago region’s unseasonably warm weather broke a record high temperature Tuesday morning, according to the National Weather Service.
The area’s previous record high temperature for Jan. 29 was 59 degrees, set in 1914, but the weather service reported 60 degrees at O’Hare Tuesday morning.
The weather agency predicts Tuesday will see a high of 63 degrees with an 80 percent chance of heavy rain.
Since temperature record keeping began in 1872, there have only been 33 days in January with temperatures above 60 degrees, the weather service said.
The last time the temperature reached 60 degrees or higher in Chicago in January was a 65 degree day on Jan. 7, 2008, the weather service said.
The heavy rain is expected to continue Tuesday night, when the temperature will begin to fall. By Wednesday morning, a mix of rain and snow is possible.
The temperature will continue to fall, and by Thursday night the low will reach a more winter-like 4 degrees, the weather service said.
