Oklahoma Monthly Climate Summary 1 A blistering final week and a return to drought transformed June from a mildly hot month into a scorcher, rekindling memories of the brutal 2011 summer. Temperatures routinely reached triple-digits across Oklahoma during the month’s final week. According to data from the Oklahoma Mesonet, the statewide average temperature finished at 79.2 degrees to rank as the 19th warmest June on record, 2.7 degrees above normal. Statewide average records date back to 1895. June’s warmth follows a pattern that began over two years ago with 22 out of the last 27 months being warmer than normal. The January-June statewide average entered the record books at 60.1 degrees, 4.9 degrees above normal. That obliterates the previous record mark of 58.9 degrees from the same period in 2006 as the state continues on a possible path towards its warmest year on record. Oklahoma’s warmest year on record came in 1954 with a statewide average of 62.8 degrees. The January-June statewide average that year was 57.4 degrees.

High temperatures across parts of the state were in the 70s as late as June 21. The lowest temperature recorded during the month was 44 degrees at Oilton and Cookson on the first. JUNE DAILY HIGHLIGHTS JUNE 1-7: A persistent upper-level low pressure system brought a very rainy first week of the month. There were plenty of storms mixed in with the showers. Plenty of large hail and high wind reports were noted on the third, including a 73 mph wind gust in Custer County. Widespread flooding was reported in northeast Oklahoma where 4-6 inches of rain fell. The upper-level low moved off to the southeast on the seventh and the rains quickly came to an end. Final rainfall totals ranged from 1-2 inches for the most part, other than the areas in the northeast and south central sections of the state where higher localized totals occurred. PRECIPITATION The month was also the 29th driest June on record with a statewide average precipitation total of 2.54 inches, nearly 2 inches below normal. A few localized areas received significant moisture during the first two weeks of the month before the state adopted the much more summer-like pattern. The Mesonet site at Skiatook led June’s rain totals with 6.86 inches while the small town of Cloudy brought up the rear with 0.45 inches. The state saw significant drought relief from October 2011 through March of this year, but the rains have since dwindled. The southeast and east central sections of the state were below 50 percent of normal since April 1, a slowdown that encompassed the entirety of Oklahoma’s primary rainy season. Statewide, the average total of 8.2 inches is 4.5 inches below normal, the 14th driest such period on record.
