Bundle up, Chicago. It's cold out there.
A bitter chill settled over the city and its suburbs overnight, dropping temperatures into what feels like single digits.
Factor out the wind chill and temperatures fell 9-degrees short of the record low of zero set back in 2007.
Monday's high of 18-22 degrees is more reminiscent of mid-January than December 6. The average high for this time of year is 38- degrees.
Get used to the deep-freeze. Temperatures are only expected to reach 20-degrees on Tuesday.
