Have we ever had a November that didn’t have a single day reach at least 50 degrees?
We have not. Chicago climatologist Frank Wachowski checked the records books dating back to 1871, and found that there has never been a November in Chicago that failed to register a 50-degree temperature. The fewest number in any November was three in 1871, followed by four in the Novembers of 1873, 1875, 1892 and 1997. Despite the cold weather that has dominated this November, most people have forgotten that the month opened relatively mild with highs reaching the lower 50s on each of the first six days. In contrast, the city has logged many mild Novembers. In 2001, there were 25 days with highs of at least 50-degrees and the Novembers of 1909 and 1931 both logged 23 days.
