Many of us woke up today to the coldest air of the season to date. This was all thanks to a powerful, polar cold front, which surged across the region early Sunday morning, November 12, 2012. Temperatures dropped by almost 45 degrees over a 24-hour period of time in some areas of northern Oklahoma with equally impressive 24-hour temperature drops of 20 to 30 degrees across the remainder of the state.
The unbridled, cold air mass continued to pool across the state Sunday night. Oklahoma City dropped to 23 degrees this morning, marking the coldest it's been since February 12 of this year. Temperatures plummeted into the middle teens in portions of extreme northwestern Oklahoma and the Panhandle.
Without a doubt, this was a significant cold front and an abrupt end to our spring-like temperature fling we were enjoying days prior to the front's arrival. However, this wasn't the strongest Blue Norther to blow into Oklahoma. Coincidently, The Great Blue Norther of 1911 also occurred on the same day (November 11) as Sunday's inferior, yet still impressive cold front.
On November 11, 1911, the afternoon temperature in Oklahoma City reached a record high of 83 degrees, before freefalling 66 degrees to a record low of 17 degrees just before midnight. The daily high temperature for Sunday, November 11, 2012 was 70 degrees reached at 2:08 a.m., while the daily low temperature was 35 degrees reached at 11:59 p.m.
