Break out the disco ball, 70s have returned to Columbus

For the first time since November 6, Columbus crossed the 70-degree mark on Tuesday. It turns out that it’s right on schedule, too — the average of the first 70 is March 9, using the 1991–2020 climate period. I should mention that the average first date 100 years ago in 1925 was March 22.

This year’s first 70 is behind some recent years, though.

2020 sticks out, and that’s the earliest first 70-degree high on record in Columbus. The latest is April 27, set in 1884. The longest stretch between 70s was a whopping 199 days from October 4, 1925 to April 20, 1926… a far cry from the 125 days we just finished.
