National Weather Service officials are expecting light snow to continue in the Chicago area in the morning areas warning of slippery roadways and windchills hovering to negative eight degrees by

CHICAGO — National Weather Service officials issued a cold weather advisory in effect until 2 p.m. Tuesday for portions of central, east central and northeast Illinois as well as northwest Indiana. Officials said dangerously cold wind chills may reach as low as 28 below zero causing frostbite to those exposed to the frigid temperatures in as little as 30 minutes.

The National Weather Service issued a cold-weather advisory for Chicago and other parts of the state this weekend, warning of “dangerously cold wind chills” that could dip as low as 20 to 25 degrees below zero.

A cold weather advisory has been extended across the entire Chicago area, with warmer temperatures slowly creeping into the forecast.

The city of Chicago is expecting to see some snow on Wednesday, but will it be enough to bring the city closer to a typical January in that department?

Trainings for Illinois residents looking to join the National Weather Service's severe storm spotter program will be held virtually for the first time this year. There will also be in-person Community Weather Preparedness training sessions.

Monday, the temperature is expected to drop to minus 3 at O’Hare International Airport. A low of minus 7 is expected at O’Hare Tuesday.

After Monday’s daytime temperatures hovered in the single digits, they are expected to dip to minus 10 to minus 3 degrees overnight, according to the National Weather Service. Flurries and isolated snow showers are also expected in the Chicago region.

Both Monday and Tuesday are non-attendance days for Chicago Public Schools students. Wind chills will be -15 to -30 Tuesday morning and -10 to -20 Wednesday morning.

After digging into the archives, weather service meteorologists found that since 1942, fewer than 5% of Chicago’s sub-zero days have occurred with no snow: of 594 sub-zero days, only 28 lacked snow cover.

Chicago faces cloudy skies and potential snow with risks of slick travel conditions and a plunge in temperatures by the weekend.
