For our last look back at the historic cold snap we just endured, January 30th (at O'Hare) was by average temperature the 2nd coldest day on record in #Chicago. https://t.co/S09u5WsCDg #ilwx pic.twitter.com/UIo394LTh2

#Chicago's (at O'Hare) 52 consecutive hours below zero from about 6pm on 1/29 to about 10pm last night (1/31) is the 4th longest such streak since 1929-30. This is an unofficial ranking list since the data does not extend back to entire period of record (to 1871). #ilwx pic.twitter.com/gxvxovbm51
