Oklahoma tried its best Al Pacino impression from “The Godfather Part III” during August, being pulled back into drought after nearly escaping its clutches completely thanks to record moisture the previous three months. The heat and dry weather roared back with a vengeance, however, and flash drought erupted for the second consecutive summer. Only 13% of the state was in drought on Aug. 8 according to the U.S. Drought Monitor, contained entirely in small patches across far southwestern and north central Oklahoma.

The unusually wet and mild weather Oklahoma enjoyed through much of May and June continued into July, providing the state with uncharacteristic summertime drought relief. The Southern Plains heat dome still managed to meander its way over Oklahoma for short periods, however, basting the state in intense heat and stifling humidity. The Oklahoma Mesonet site at Pauls Valley reached a network-record heat index of 126 degrees on July 13, besting the previous record of 125 degrees from Calvin back on Aug. 9, 1999. The Mesonet’s heat index records date back to 1997.

June took up the slack for May’s relatively tame severe weather output—at least by Oklahoma’s standards—with 10 tornadoes and two possible derechos that left over half of a million Oklahomans without power. While storms threatened the state throughout the month, the most intense severe weather was concentrated within just a few days from June 15–18 thanks to two powerful storms systems, both aided by an unusually strong jet stream overhead.

Central Oklahoma has often been characterized as a haven for tornadoes, with some of that perception based in reality—and myth. There has been nothing mythical about that reputation in 2023, however. At least 11 tornadoes touched down in central Oklahoma on May 11, adding to persistent tornadic activity in that region during the previous 4 months of the year. Through just 5 months, the central Oklahoma counties of Cleveland and McClain broke their records for number of tornadoes in a calendar year with preliminary totals of 13 and 11, respectively.

Drought relief and severe weather topped April’s weather headlines with a parched northwest Oklahoma seeing its first significant moisture in months and central Oklahoma enduring a tornado outbreak. Eighteen tornadoes touched down on April 19, a day when severe weather was thought to be limited by a warm atmospheric lid above the surface. High temperatures over 90 degrees combined with a potent dryline to break that lid and initiate the storms that would eventually spawn the twisters.

At this year’s 2023 Oklahoma Learning Innovations Summit, it was announced that the Oklahoma Mesonet was named the winner of the 2023 Team Leadership Oklahoma Online Excellence Award by the Oklahoma Council for Online Learning Excellence (COLE). The award praises the Mesonet’s “great talent and expertise within distance learning throughout the State of Oklahoma.” Each nominee goes through a review process by COLE and the Online Consortium of Oklahoma.

Oklahoma’s oddly persistent caste-like rainfall pattern—with those to the north and west of Interstate 44 seeing near-record dryness and those to the south and east experiencing abundance—continued during March. Rainfall totals to the northwest of I-44 were generally a half-inch or less, while amounts of 5-8 inches were quite common to the southeast. Ten Oklahoma Mesonet sites in far northwest Oklahoma failed to record more than a tenth of an inch of rain for the month, with another 17 stuck below the quarter-inch line on the rain gauge.

A potent storm system—labeled by forecasters as “historic” and “unprecedented” for February—struck Oklahoma on Feb. 26 with the full fury and power of a classic springtime severe weather outbreak. At least 10 tornadoes were confirmed during the event, with that total almost guaranteed to creep higher with further investigation by National Weather Service personnel. The preliminary total of 10 shatters the previous February record of 6 set in both 1975 and 2009. Accurate tornado records for Oklahoma date back to 1950, and the long-term average for February is 0.3.
