Friday it got up to 70 (call it 21°C) in Oklahoma City, which was followed by a particularly cold weekend incorporating a few minutes’ worth of sleet. (Nastier stuff, and more of it, fell to the east.) Now 70 is not the record for the date: that would be 77, set on 1/11/1911. This immediately got people thinking about 11/11/1911, on which date we got both a new record high (83) and a record low (17), and someone wondered if the whole year was freakish, weatherwise.
I dug through the records, which go back to 1891, and while I’m not prepared to say 1911 was the freakiest year on record, it had more than its share of weirdness: thirteen record highs (I had said twelve, but I missed one) and seven record lows.
Weird pattern #1: high 83 on 1/31, 90 on 2/1. (The 1/31 record holds up for all of January; we’ve since had one warmer day in February.)
Weird pattern #2: four record highs in June, two record lows in July, two record highs in August.
Keep in mind, all this happened in 1911, back when the temperature of the planet was constant; it would remain so until the introduction of the first sport-utility vehicle, the Chevrolet Suburban, for model year 1935, which promptly set off the Dust Bowl.
