[Ed. – Please. I can remember it dropping more than that in Oklahoma, several times since I was a kid. As the article says, it’s called a “blue norther.” We love you, Texas, but stick to what you’re good at. In Oklahoma, instead of “scenery,” we have “weather.” It’s the Sooner State’s main extracurricular activity. :-)]
Grand prize for the most dramatic frontal passage goes to West Texas, where the cold air mass plowed south on Saturday in the form of a classic “blue norther” (sometimes called a Texas norther). A mesonet station about 6 miles west of Denver City, TX, reported a temperature drop of 36°F in just 10 minutes–from 21°C (70°F) to 1°C (34°F)–accompanied by winds of 40 knots (46 mph) gusting to 69 knots (79 mph). Thanks to Anton Seimon (Appalachian State University) for finding this nugget.
Temperatures across Texas at 4:00 pm CST Saturday ranged from 6°F at Dumas (nearby Dalhart sank to a record-low –8°F by Sunday morning) to a record-hot 92°F at McAllen. Midland set a record high of 80°F on Saturday afternoon, but by 11:59 pm CST, the city’s official temperature had plummeted to 18°F, just one degree short of the day’s record low! It was Midland’s biggest one-day temperature spread for any date in records going back to 1930. More than a century ago, a blue norther on November 11, 1911 (11/11/11) managed to pull off the twin-record-in-one-day trick in both Oklahoma City, OK (83°F and 17°F) and Springfield, MO (80°F and 13°F). Both of these Oklahoma City records still stand.
