Illinois All-Time Coldest Temp Record Broken!* Numerous Other Records Broken During Historic Cold Period

(2:30PM - 1/31/19) Widespread all-time, high and low temperature records have been broken across the state the last several days, associated with the historic-record breaking-life threatening cold that has been ongoing as a lobe of the Polar Vortex moved through. Many of these records were not just broken, smashed for many areas.

Additionally...The all-time coldest temperature for the state of Illinois likely was broken. A low temp of -38 occurred in Mount Carroll this morning (1/31/19). This breaks the previous record of -36, which occurred on 1/5/1999 in Congerville. For now this is preliminary, as things have to be reviewed by Illinois Climatologists, but it's looking likely a new record has been set.
