Copyright © 2013 Board of Regents of the University of Oklahoma. Oklahoma Monthly Climate Summary 1 It was not the wettest July on record in Oklahoma, at least not on a statewide basis. That mark belongs to 1950’s statewide average of 9.26 inches. Nor was it the coolest. That title is held by 1906’s statewide average of 75.9 degrees. Nevertheless, this July will be remembered as one of the wettest and mildest in recent memory, especially compared to the blast furnace versions of the last few summers. It featured a July 4th holiday with highs in the 80s and lows in the 50s, and enough rain to kick drought to the curb across much of the state. According to preliminary data from the Oklahoma Mesonet, July’s statewide average precipitation total was 5.11 inches, a surplus of 2.37 inches and ranked as the 15th wettest since records began in 1895. The statewide average temperature was a very pleasant 79.6 degrees, 2 degrees below normal and the 28th coolest July on record. The highest temperature recorded during the month was 107 degrees at Alva, Buffalo and Freedom on the ninth, and again at Grandfield on the 11th. The lowest temperature reported was an unseasonably chilly 49 degrees at Seiling on July 2.

The highest maximum temperatures slowly increased from a reported 88 degrees in Grady on the 1st to 93 degrees in Grady on the 3rd. The lowest maximums gradually climbed from 76 in the panhandle to 81. Lows ranged from 50 in Bristow to 65 in Medicine Park. These cool minimums broke records in McAlester on all three days—a daily low of 61, 56 and 54, as well as record daily low mean temperatures of 71 on the 2nd and 3rd. Despite an isolated measure of .68 inches of rain in Boise City on the 2nd, rainfall was negligible throughout the state. An average wind speed of 15mph was measured in Boise City on the 3rd; however, the majority of Oklahoma kept an average wind speed of less than 10mph Monday through Wednesday. JULY 4-5: Independence Day had a few scattered showers and thunderstorms in the eastern one-third of Oklahoma as well as a few lighter periods of rainfall in the west. Showers and weak storms continued on the 5th in the northwest and central one-third portions of the state. Except for .27 inches in McAlester, precipitation amounts were less than a tenth of an inch on the 4th. Likewise, rainfall was generally less than a tenth of an inch on the 5th; however, about two-tenths of an inch fell in Burneyville and Weatherford, and .25 inches fell in Medford and Ringling. Maximum temperatures continued on a warming trend, with highs reaching 98 in Grady on the 4th and 101 in the southeast on the 5th. The lowest maximum was 86 degrees While nearly all areas of the state received beneficial rain, a wide discrepancy existed between locations. The Mesonet’s Kingfisher site led the state with 10.99 inches of rainfall during July while Goodwell brought up the rear at 1.02 inches. Oklahoma City’s total of 9.84 inches, 6.91 inches above normal, ranked this July as its second wettest on record, bested only by 1996’s 11.9 inches. That also keeps Oklahoma City on pace to have its wettest calendar year on record with a January-July total of 41.69 inches, more than 3 inches ahead of 2007’s total of 38.15 inches over the same period. The calendar year record for Oklahoma City currently stands at 56.95 inches from that same year of 2007. Records for Oklahoma City date back to 1891. On the other side of the moisture spectrum, the Mesonet site at Goodwell has recorded a meager 5.2 inches of rain since the first of the year. That’s the third driest January-July for that area since 1910. Not surprisingly, 2011 earned the driest mark for Goodwell with 1.73 inches.
