A mix of snow and rain will make for hazardous driving conditions Wednesday morning in the Chicago area, the National Weather Service is warning.

Rain will change to snow as temperatures quickly fall from the 30s in the morning to below freezing in the afternoon, the weather service said. A winter weather advisory is in place until noon Wednesday.

Less than an inch of slushy snow is expected to fall across most of Cook County, the weather service said. The worst driving conditions will be northwest of Interstate 55.

The weather service urged drivers to allow for extra travel time, especially across the north and western parts of the Chicago area.

Dozens of suburban schools were closed Wednesday or opening late due to the winter weather.

By 6:50 a.m. Wednesday, at least 140 flights were canceled at O’Hare International Airport, the Chicago Department of Aviation said. Midway Airport saw two cancellations in the last 24 hours.

A bitterly cold Arctic air mass will arrive behind a strong cold front on Thursday, according to the weather service. Friday could see below-zero temperatures, with a wind chill of 20 to 30 degrees below zero.
