Copyright © 2012 Board of Regents of the University of Oklahoma. Oklahoma Monthly Climate Summary 1 Winter roared back into Oklahoma during February, providing significant drought relief to much of the state while dumping as much as three feet of snow in the northwest. According to preliminary data from the Oklahoma Mesonet, the statewide average precipitation total for February was 3.03 inches, 1.27 inches above normal. That would rank the month as the 13th wettest February since records began in 1895, although melting snow in the northwest could push that mark higher. Radar estimates indicate 2-6 inches of liquid equivalent precipitation fell across the state during the month. February was the wettest month in Oklahoma since April 2012, which had a statewide average of 3.81 inches. A statewide average deficit of more than 12 inches still exists since the beginning of last May, the beginning point of this second round of drought that has persisted since October 2010. The deficit since that point is nearly 25 inches. Not only was the month wetter than normal, it was also cooler than normal. According to the Mesonet, the statewide average temperature finished at 40.7 degrees, 1 degree below normal – only the seventh month out of the last 35 to accomplish that feat. The winter period of December 2012-February 2013 ranked as the 30th warmest at 1.9 degrees above normal and 35th wettest at 0.6 inches above normal. The month’s last storm system was also its most powerful. Severe thunderstorms, hail, freezing rain and snow pounded the state on Feb. 24-26. Strong winds of over 50 mph whipped the snow, often accompanied by thunder, into drifts as high as 10 feet that paralyzed much of northwestern Oklahoma. More than 36,000 electrical customers were left without power thanks to ice-coated power lines and trees, and nearly all highways across extreme northwestern Oklahoma were shut down as roads drifted shut. The heavy, wet snow crumpled awnings and in some cases, roofs. One fatality was attributed to a roof collapse at a private residence in Woodward. The snow totals were extreme, and in some cases, possibly record-breaking. The preliminary February snowfall total of 42.5 inches from the small Ellis County town of Arnett would break the state’s all-time snowfall record for any month if it verifies. That mark currently stands at 39.5 inches from Buffalo, set in February 1971. Alva, to the northeast in Woods County, recorded a preliminary total of 35.6 inches. The month began with 92 percent of the state depicted in at least extreme drought by the U.S. Drought Monitor, and 40 percent considered to be in exceptional drought. The Drought Monitor’s intensity scale slides from moderate-severe- extreme-exceptional, with exceptional being the worst category. The latest report released on Feb. 28 portrays remarkable improvement with only 12 percent of the state in FEBRUARY 2013 Oklahoma Monthly Climate Summary February 2013 Statewide Extremes Description Extreme Station Day High Temperature 75ºF Waurika, Anters 17, 18 Low Temperature -2ºF Hooker 22 High Precipitation 4.61 in.
