What to know about the winter storm coming ahead of the holiday weekend
Temperatures could plummet into the single digits. Exposed skin can develop frostbite within 30 minutes.

City officials are urging residents to remain indoors until Saturday as a winter storm is set to create dangerous conditions.
The Department of Streets and Sanitations will deploy eight salt trucks, beginning Thursday, according to a news release. Whiteout conditions and large snow drifts will make driving unsafe, so officials are encouraging residents to avoid the roads if at all possible, until the snowfall ends Saturday.
There are two warming shelters located in Harvey—the Harvey Police Department and Harvey Fire Department—where residents can go, if need be.
The National Weather Service has implemented a winter storm advisory for much of the Chicago area. Snowfall is estimated to be anywhere from six to 12 inches, with wind gusts of nearly 55 miles per hour, moving eastward as the week progresses.
As of 11a.m. this morning, snowfall is already creating visibility difficulties and bringing winds gusts of 35mph, according to the NWS tracker.
Temperatures are predicted to plummet into single digits. Wind chill could bring that to -25 degrees Thursday evening and -40 degrees Friday morning, NWS officials warned.
