Last night, the temperature got down to -21°C for the first time since 31 January 2019—when it got down to -29°C. But even in 2019 we only had to endure, at most, 7 days below freezing. Today is our 10th in a row, with another 6 predicted. (It may get up to 2°C next Sunday.) If the freeze goes through Friday, we'll have had a longer freeze than the 14 days we had ending 7 January 2018.
Of course, I lived through the longest below-freezing period in Chicago's history, the 43 days between 28 December 1976 and 8 February 1977. Wow, I hope that never happens again.
And hey, spring begins two weeks from tomorrow.
