Tulsa, Oklahoma – Dry skies across Eastern Oklahoma and Northwest Arkansas Saturday will give way to another round of thunderstorms Sunday evening, bringing the potential for heavy rain and gusty winds. The storm threat comes ahead of a significant midweek heat wave, with temperatures climbing sharply by Tuesday.
According to the National Weather Service in Tulsa, showers and thunderstorms are expected to develop Sunday night as another disturbance tracks across the region. Storm chances are highest south of Interstate 40, where localized downpours and cloud-to-ground lightning could impact communities including McAlester, Poteau, and Fort Smith.
