May brought an abrupt slowdown in tornado activity after a historic start to 2026. The year opened with January tying its monthly tornado record, followed by a record-setting March and an active April that pushed the preliminary annual count to 57 by the end of that month. May is normally Oklahoma’s most active tornado month, averaging 32.7 tornadoes since 2000, but the month produced only two official tornadoes, both on May 27 in southeastern Oklahoma. The record fewest for May is zero, set in 2005. Another possible tornado near Hobart remained under investigation.

Oklahoma seemingly took a detour from February straight into July during what became the warmest March on record for the state. The unusual heat arrived on the heels of both the warmest winter and February on record. The records didn’t stop there, as the state also experienced its highest March temperature on record and a record number of tornadoes. The heat combined with dry and windy conditions to intensify the state’s ongoing drought and elevate wildfire danger.

The Oklahoma Mesonet and the Cooperative Institute for Severe and High-Impact Weather Research and Operations (CIWRO) at the University of Oklahoma are jointly hosting a 1-day, in-person, professional development workshop for Oklahoma 3rd-6th grade public school teachers. The workshop will focus on the atmospheric ingredients that can spur tornadoes, plot weather data on maps and graphs, and hands-on activities.

February ended as the warmest on record across Oklahoma, a distinction that also pushed the climatological winter of 2025–26 to its warmest on record. The unusual warmth combined with expanding and intensifying drought to create critical fire weather conditions across much of the state. Those ingredients culminated in a mid-February wildfire outbreak that burned more than 300 square miles and forced evacuations across multiple counties. It was a month defined by record heat, deepening drought and wind-driven flames.

January 2026 delivered a little bit of everything Oklahoma weather is known for — a rare January tornado outbreak, a major winter storm accompanied by arctic cold, and continued drought across much of the state. The month featured both destructive severe weather and prolonged freezing conditions, including one of the most impactful snow and ice events in recent memory. By month’s end, more than two-thirds of Oklahoma was in drought, even as snow cover lingered across the northern half of the state. It was a month defined by sharp contrasts and high-impact weather from start to finish.

If moisture and cold weather topped your December weather Christmas list, you likely didn’t enjoy the lump of coal Mother Nature delivered instead. December 2025 finished as Oklahoma’s second-driest and fifth-warmest on record, dating back to 1895, allowing drought to flourish once again across much of the state. The unusual warmth was especially pronounced during the week surrounding Christmas, highlighted by the warmest Christmas Day in Oklahoma history.
