CHICAGO (CBS) — Remember Tuesday? When Chicago set a record for warmth?
What a difference two days make.
Thursday night, temperatures were more than 60 degrees lower!
Overnight temperatures around the Chicago area will plunge to near zero, with dangerous wind chills of up to minus 15 degrees.
There is a wind chill advisory in effect for outlying counties north and west of Chicago, including McHenry and DeKalb. Overnight, wind chills there will be 15 to 25 degrees below zero.
A wind chill advisory–which will be in effect from midnight until 10 a.m. Friday– means that very cold air and strong winds
will combine to generate low wind chills. This will result in frost bite and lead to hypothermia if precautions are not taken.
If you must venture outdoors, dress in layers and make sure you wear a hat and gloves.
High temperatures will remain in the teens on Thursday and Friday, with light snow possible.
There is a chance of more light snow on Saturday, but temperatures will rise into the 30s.
