There’s never been anything in October quite like the warmth we’ve enjoyed the past few days. Our city is in the midst of a record breaking spell of late season warm weather. Not only have each of the past three nights remained at or above 70°, producing new records for the warmest overnight temperatures, but overnight lows have also managed to exceed the normal highs observed this time of year. A single set of back-to-back nighttime 70s—let alone three 70s in a row—have never before occurred here in 135 years of official observations. Tuesday morning’s 71° low tied the city’s all time warmest October nighttime temperature, first set on Oct. 1, 1971.
White Sox fans benefit Wednesday evening from the slowdown of an approaching cold front. Unseasonably warm south winds now appear determined to hold summer-level temperatures in place for tonight’s game.
