Yesterday's 14°C high temperature made it the second-warmest Christmas on record in Chicago, missing by a lot the 17°C record set in 1982. The warmth continued overnight: the temperature at O'Hare hit 14°C just after midnight, surpassing the 13°C record for December 26th set in 1971. Today's forecast calls for 20°C.
These temperatures would be normal in October and April—or Atlanta and Dallas.
Yesterday Parker got an hour and a quarter of walks; today he'll get about the same. And I may even open windows in my apartment.
Temperatures should get more seasonal promptly. A cold front should get us back to normal December temperatures tonight, and we have rain and snow coming in Sunday night. New Year's Eve should give us a close-to-normal 1°C high.
