Potentially dangerous cold temperatures came to the Chicago area Saturday night following a winter storm that brought several inches of snow to many communities.
A wind chill advisory went into effect for DeKalb, Grundy, Kane, Kendall, LaSalle and McHenry counties at 9 p.m. Saturday and lasts until 10 a.m. Sunday, according to the National Weather Service.
Bone-rattling wind gusts could potentially create wind chills as low as 20 degrees below zero through Sunday, according to the National Weather Service.
Highs could also sink to a low of just 5 degrees overnight.
If you absolutely need to venture outdoors, make sure to wear appropriate clothing including a hat and gloves. Due to the extremely cold wind chills, frostbite could occur as quickly as 30 minutes, forecasters said.
Extremely cold temperatures are expected to continue early Sunday, with the morning windchill dropping to minus-15 degrees.
A warm up doesn't appear to be in the immediate future as high temperatures are expected to be in the mid teens Sunday.
The start of the work week will likely be slightly warmer with highs in the low 20s Monday.
