Tulsa, Oklahoma – Rising tropical moisture streaming in from the southeast will bring scattered thunderstorms and downpours across southeast Oklahoma and northwest Arkansas this weekend, raising the risk of lightning, gusty winds, and brief flooding on roads.
According to the National Weather Service in Tulsa, medium chances (20–60%) for showers and thunderstorms are expected Saturday, especially along the I-40 corridor, including McAlester, Fort Smith, and surrounding counties. By Sunday, rain chances decrease slightly (20–30%), but isolated storms remain possible from Muskogee to Fayetteville and along US-69.
Storms may trigger cloud-to-ground lightning, locally heavy rain, and brief wind gusts—conditions that could lead to quick street flooding and power flickers, particularly in low-lying areas. Residents near Poteau, Tahlequah, and Sallisaw should remain alert to rapidly changing conditions and avoid driving through flooded roadways. Outdoor plans in Bartlesville or Okmulgee may be interrupted by afternoon thunder, so monitor local updates closely.
To stay safe, head indoors at the first sound of thunder, secure outdoor items, and avoid flood-prone areas. This round of storms could be the region’s wettest since early June.
Rain and storm chances remain in effect through Sunday evening, with more updates expected if threats persist or new advisories are issued.
