It may have been cold Sunday night, but it's going to be seriously freezing tonight and will continue to be so through Tuesday night, according to the National Weather Service based in Romeoville.
A wind chill advisory and hazardous weather alert was issued Monday for the Lincoln-Way area, with a low temperature of 2 below zero that felt much more like 18 below when the wind blew.
In the simplest terms, any longtime skin exposure's going to lead to hypothermia, the forecast said.
"With wind chill values this low, frostbite to exposed skin can occurr in 30 minutes," the advisory said.
The warning stays in effect until 10 a.m. Tuesday, but don't expect any big increase in the temps. The high is predicted to be 9 and the overnight Tuesday low will be about 5, forecasters said.
When the daytime high reaches 22 on Wednesday, it will feel like a day at the beach compared to the previous days. And the good news, so-called, is here won't be any fear of snow until Thursday, when there's a 20 percent chance predicted for during the day and 50 percent chance that night.
"If you must venture outdoors," the advisory said, "make sure you wear a hat and gloves."
