Tulsa, Oklahoma – Thunderstorms could spark across eastern Oklahoma and northwest Arkansas by Friday afternoon, bringing a 40% chance of severe weather and elevated lightning risks from Tulsa to Fort Smith.
According to the National Weather Service in Tulsa, a surge of warm, humid air will increase instability across the region, setting the stage for isolated but potentially strong storms. The timing and location remain uncertain, but the highest threat appears to stretch from McAlester northeast toward Fayetteville and Bartlesville, peaking late Friday and into the overnight hours.
Cities under the limited severe threat include Muskogee, Tahlequah, and Sallisaw, where damaging winds and frequent lightning could pose risks to travel and outdoor activities. Although widespread severe weather is not expected, residents should stay weather-aware as storm chances develop. Emergency managers advise securing loose outdoor items and reviewing shelter plans, especially in mobile homes or rural areas.
This system comes amid rising May temperatures, with dew points climbing into the 60s by midweek — a pattern that often precedes spring severe weather outbreaks in the region. While the overall threat remains low to medium, confidence in exact details is still developing.
More updates are expected as models refine storm timing. Watches or warnings could be issued by Friday morning.
