CHICAGO (CBS) — Monday’s overnight temperature is expected to drop to 18 below zero.

That would come within two degrees of the 15 coldest days ever in Chicago. Overnight wind chills are likely to be 30 to 45 degrees below zero.

The worst-ever wind chill happened on Christmas Eve 1983: minus 57, adjusted for a new wind chill formula adopted about 10 years ago. Under the old formula, the chill was recorded at minus 82.

The coldest day ever happened nearly 30 years ago on Jan. 20, 1985.

It was 27 degrees below zero that day.
