CHICAGO (WLS) -- The bitterly cold weather is expected to continue overnight with wind chills well below zero into Wednesday morning.
A cold advisory will be in effect until midnight Wednesday, but as a cold snap ends, a snow chance starts.
Temperatures will warm into the low 20s on Wednesday, but there will be the chance of some snow in the afternoon and evening hours, said ABC7 Chicago Meteorologist Larry Mowry.
A dusting to an inch or so will be possible with some spots maybe seeing as much as 2 inches of snow. That's not a whole lot snow, but it will be enough to create some slippery spots on the roadways during the day and especially Wednesday evening.
This comes after some residents at a senior apartment building on the South Side said they did not have enough heat during frigid temperatures on Tuesday.
Building management said of the 10 complaints they received, only one unit's temperature was below the 68-degree temperature required by the City of Chicago. They contacted their heating vendor to address the issue.
Tuesday morning, Amtrack announced extensive delays and cancellations due to the extreme weather. Metra is also used switch heaters to try to prevent the same thing from happening.
"Our steel doesn't like the cold any more than we do, it contracts in extreme cold," said spokesperson Michael Gillis.

Both Monday and Tuesday were non-attendance days for Chicago Public Schools students.
The weather has also kept mechanics busy. The owner of Wells Automotive Service Frank Guske said the low tire pressure warning light will often times turn on during cold snaps.
"When it gets cold and the temperature drops, everything condenses down, contracts, that makes the light come on. Usually you just get away with just refilling them. If you have one tire that's lower than the other, then there's a problem. The seal is bad or there's a puncture," he explained.
Guske said being prepared is key. AAA explained the importance of having an emergency kit in the car at all times.
"You don't know what might happen, as you're driving or you run into a problem. That emergency kit should include jumper cables, you also want to have your cell phone charger, you want extra blankets and some hats and some gloves, some extra bottles of water and you also wanna have some snacks." AAA Spokesperson Molly Hart said.
In such cold conditions, frostbite can develop on exposed skin in 10 minutes or less, so people should don coats, hats and gloves and minimize time outdoors, said Connor Smith, a meteorologist with the National Weather Service in Bismarck.
Warning signs of frostbite include numbness, pale or waxy skin, redness or pain.
The Centers for Disease Control and Prevention recommends immediately getting out of the cold and into a warmer environment if this occurs. Avoid rubbing the frostbitten area or walking on frostbitten feet or toes, as this can cause more damage. Instead, put the frostbitten areas in warm - not hot - water. If this is not available, use body heat from other parts of the body to warm the area, such as by placing frostbitten hands or fingers in an armpit. Do not use heating pads or heat from a stove, as the affected areas may easily burn.
People with asthma, chronic lung disease, or other respiratory conditions or illnesses are at higher risk when temperatures drop because cold, dry air irritates the airways, said Dr. Haitham Khraishah, a preventive cardiologist at University Hospitals Harrington Heart & Vascular Institute and an assistant professor of medicine at Case Western Reserve University in Cleveland.
This leads to greater inflammation and causes muscles around the airways to constrict, which can lead to wheezing, coughing, shortness of breath or a burning feeling in the chest, especially during exertion.
In the summer, it's not the heat that gets you, it's the humidity. In winter, that means it's not the cold that gets you, it's the wind.
As Chicagoans bundle up to brave the cold, many have also been experiencing public transit delays.
Amtrak said the weather is forcing some service cancellations, advising riders to follow the latest information online.
