Extremely low temperatures and snow forecast for the early morning hours Wednesday is expected to create hazardous driving conditions during the morning rush hour, the National Weather Service is reporting.
Between 2 and 4 inches of snow is expected to fall beginning at midnight Wednesday. The weather service said snow is expected to immediately accumulate on roadways because low temperatures will minimize the effectiveness of road salt.
The winter weather advisory is in effect for DuPage, Cook and nearby counties through 10 a.m. Wednesday.
Snowfall rates could reach a peak of a half-inch per hour.
The weather service is also forecasting wind chills reaching 15 to 30 degrees below zero Wednesday afternoon and into Thursday morning.
