Despite recent beneficial rains, drought is on the rise once again in Oklahoma. Northwest and east-central sections of Oklahoma saw drought increase on this week’s U.S. Drought Monitor map, and overall coverage has increased from 3% of the state to more than 15% in the last three weeks. This is the fourth in a series of drought intensifications Oklahoma has seen since this larger drought episode began back in late summer of 2021.

Oklahoma’s weather was mostly lamb during March, although it did have its lion moments. The state experienced only one true outbreak of severe weather, but that single event on March 14 was significant nonetheless with two confirmed tornadoes in McIntosh and McCurtain counties and hail greater than softball size in Ada. Remarkably, Oklahoma had gone nearly five months without a confirmed tornado since the previous two back on October 24, 2023, in Garvin and Potawatomie counties.

Wildfires tore through northwestern Oklahoma in late February, propelled by severe winds gusting to over 60 mph, relative humidity values in the teens, and temperatures soaring more than 30 degrees above normal. Over 140,000 acres were scorched in Oklahoma, with Oklahoma Emergency Management officials reporting the loss of at least 13 homes, as damage assessments continued through the month's end. Additionally, reports of lost livestock and other structures emerged.

Winter made a striking return to Oklahoma in January, surprising a state that had just experienced its fourth-warmest December on record. This frosty resurgence brought with it a myriad of wintry phenomena, including freezing fog, freezing rain, snowstorms, a blizzard warning, an ice storm warning, and the lengthiest stretch of sub-freezing temperatures since the infamous Arctic air outbreak of February 2021. Following a seasonably mild first week, Arctic air surged southward in multiple waves.

December was unusually warm across all of Oklahoma, and uncommonly wet across the northwestern third. A prolonged absence of Arctic air led to the state’s fourth warmest December since records began in 1895, and contributed to 2023’s rank as the 10th warmest calendar year. The month continued a string of Decembers with above normal temperatures in the last decade. The Decembers of 2019 and 2015 ranked as the 13th and sixth warmest across the state, respectively.

The Oklahoma Mesonet’s temperature data tell the story of a dry and unusually warm November, but there was actually a good dose of winter during the month, as well as a nice measure of rain at the end. The state’s first significant wintry precipitation of the season fell in the state on Thanksgiving Weekend across the northwestern half. Totals generally ranged between 2-4 inches, but a swath of 4-6 inches occurred across far northwestern Oklahoma and the eastern Panhandle. Isolated totals of 8-9 inches were reported in parts of Beaver and Harper counties.
