Tulsa, Oklahoma – South winds and dangerous heat could create hazardous evening conditions across eastern Oklahoma and northwest Arkansas, with heat index values topping 100°F and gusts up to 35 mph expected to persist through late Sunday.
According to the National Weather Service in Tulsa, heat indices between 100 and 103 degrees are ongoing across the region, with significant wind gusts impacting areas like Tulsa, Muskogee, and Fort Smith. Winds will gradually calm overnight, but residents are urged to limit outdoor activity and hydrate frequently.
Cities across eastern Oklahoma—particularly those along U.S. 69 and I-40—may experience limited heat-related risks until after midnight. While no formal heat advisory has been issued, the combination of high humidity and sustained warmth poses health concerns, especially for the elderly and those without air conditioning. Wind gusts may also impact unsecured outdoor items and elevate fire danger in dry areas.
No severe weather is expected Monday, but scattered thunderstorms could return Tuesday through Saturday. Western Arkansas and far eastern Oklahoma will see the earliest storm chances.
Heat and wind risks will subside overnight, but summer conditions will intensify midweek. Highs in Tulsa are forecast to reach 94°F by Friday.
