Extreme cold to persist in Chicago with wind chills as low as -39 degrees
CHICAGO (CBS)-- Dangerously cold conditions will continue throughout this week, with below-zero temperatures continuing until Tuesday night.
The deepest arctic air mass in five years remains entrenched over the region through Tuesday, keeping temperatures below zero and sending wind chills down to dangerously cold figures between -25° and -40° early Tuesday morning.
A Wind Chill Warning is in effect until 12 p.m. on Tuesday, and a Wind Chill Advisory is in effect through 9 a.m. on Wednesday. Experts warn that frostbite could develop on exposed skin in 30 minutes.
A fast-moving clipper system was set to bring a period of light snow Monday night, mainly south of the I-80 corridor. Although accumulations were to be light, the snow could cause travel impacts as it falls on extremely cold roads.
The core of the arctic air mass begins to shift east on Tuesday with slowly moderating temperatures for midweek. However, wind chills remain bitterly cold Tuesday night into Wednesday morning as strong southwest winds making it feel like -15° to -20°.
After a brief break from the extreme cold midweek, another push of arctic air arrives Friday into Saturday with lows around zero and wind chills -20° to -25°.
Tonight: Partly cloudy with light snow developing south of I-80. Dangerously cold with lows -9 to -15 degrees. Wind chills -20 to -30 degrees.
Tuesday: Partly sunny, continued bitter cold. Highs around 0°. Wind chills -15 to -20 degrees.
Wednesday: Mostly cloudy. Not as cold with highs in the teens. Lows 5 to 10 above zero.
