February of 2010 has come and gone, and what a month it was!
It was one of the snowiest on record, and certainly in the top 10 coldest. Averaging temperatures from around Texoma gives us a monthly average reading of 38.2 degrees. This is 6.7 degrees below the 30-year “normal” value.
Since Texoma climate records are not as complete as those for Dallas and Oklahoma City, I combined their coldest February numbers to arrive at a ranking for Texoma.
Dallas had their 5th coldest on record with an average temperature of 41.7, while Oklahoma City had an average temperature of 36.5 degrees which is estimated to be the 12th coldest for them. Crunching those numbers puts us as 8th coldest.
The average Feb. temperature for Texoma was very close to the average between the Dallas and OKC numbers, so I’m confident in the conclusion here. It was the coldest Feb of the 21st Century here as well.
Why so cold? It was mainly due to a large trough in the east which deflected many cold air masses southward throughout the month.
As for precipitation, rain and melted snow added together gave us totals generally between 2-1/2 and 4 1/2”, which ranged from near normal to in some cases about twice the normal. A "normal" February would see from 2.40 at Ardmore and Ada, to 2.6" at Sherman and Durant to about 3" at Antlers and Paris. See the two maps below for cities and Feb. precip. totals
