The record for consecutive 21°C-plus days in Chicago is 5, set 15-19 November 1953. Today will be the third in a row, with the forecast showing the fourth, fifth, and sixth coming this weekend and on Monday.
In other sunny news, the electoral map has shifted a bit overnight:
Arizona's count has slowly shifted away from Biden while in both Georgia and Pennsylvania the count has put Biden ahead. In Georgia, Biden now leads by 1,200 votes, with a few thousand absentee ballots from heavily-Democratic areas near Atlanta. In Pennsylvania, Biden's 6,000-vote lead will likely grow as the final votes come in from Philadelphia, which has gone 90-10 for him in some places. And, of course, Biden leads in the national popular vote, by about 4 million. Both candidates have so far received more votes than any in history.
Note that if the six undeclared states solidify in their current colors, the Electoral College vote will exactly mirror 2016's: 306 to 228. That would be a delicious irony, showing that history doesn't repeat itself, but it does rhyme.
