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. The initial wave blanketed northern Oklahoma with snow on Jan. 8-9, accompanied by a blizzard warning in the Panhandle.
Snow accumulations were generally modest, though the western Panhandle saw over 6 inches, coupled with wind gusts exceeding 60 mph. This led to near-zero visibility and whiteout conditions, resulting in road closures.
Subsequent blasts of frigid Arctic air infiltrated the state starting late on the 11th, persisting until the morning of the 17th, holding much of Oklahoma in a deep freeze for over 100 hours.
Some northern regions endured over 100 hours below 20 degrees Fahrenheit, a clear indicator of the polar origin of the air mass.
Mercury readings plummeted to as low as minus 15 degrees, marking the coldest recorded temperature in the state since February 26, 2021, when Nowata recorded minus 22 degrees. Additionally, light snowfall graced northern and eastern Oklahoma on the 15th.
After a brief respite, winter made a formidable return.
Freezing rain swept across the state late on the 21st and persisted through the morning of the 22nd, prompting an ice storm warning for far eastern Oklahoma due to anticipated heavier ice accumulations and gusty winds.
Up to three-tenths of an inch of ice coated the southeastern two-thirds of the state, leading to traffic disruptions and hundreds of motor vehicle accidents.
Portions of Oklahoma’s turnpikes and interstate highways turned into impromptu parking lots for numerous semi-trucks.
The ice was a hazard to pedestrians as well, with dozens of slip-and-fall accidents reported by state hospitals. Although temperatures finally climbed above freezing on the 22nd, inclement weather persisted through the 27th, with successive waves of chilly rain under perpetually gray skies.
Fortunately, the month concluded on a brighter note, with temperatures reaching the 60s and 70s from the 28th through the 31st.
According to preliminary data from the Oklahoma Mesonet, the statewide average temperature for the month was 34 degrees, 4.3 degrees below normal and ranked as the 26th coldest January since records began in 1895.
Reflecting on the first two months of climatological winter, encompassing December and January, the statewide average temperature stood at 39.5 degrees—marginally above normal by 0.3 degrees—and ranked as the 42nd warmest such period on record.
