Tulsa, Oklahoma – Heavy rainfall of 1 to 3 inches could impact areas near U.S. Highway 75 and Interstate 44 through Saturday night, with localized flooding possible in southeast Oklahoma and western Arkansas.
According to the National Weather Service in Tulsa, the potential for excessive rainfall continues Saturday, with the focus shifting toward southeast Oklahoma and western Arkansas. Rain and thunderstorms are expected to gradually end by Sunday morning.
Forecasters indicate a 5% to 25% chance of excessive rainfall Saturday into Saturday evening. Widespread rainfall amounts of 1 to 2 inches are expected south of I-44, with localized totals near 3 inches possible where storms train over the same areas.
The severe weather threat is expected to remain mostly south of Tulsa, though stronger cells could produce small hail. The primary concern remains heavy rainfall and isolated flash flooding.
Communities including McAlester, Muskogee, Fort Smith and Fayetteville are within the higher rainfall corridor. Travel along I-40, I-44, U.S. 69 and U.S. 75 may be slowed at times due to ponding water and reduced visibility during heavier downpours.
Dry conditions in recent days may limit widespread impacts, but urban and low-lying areas could still experience brief flooding if rainfall rates intensify.
Drivers, weekend travelers and students returning Sunday should monitor updated forecasts as storms move east.
The National Weather Service encourages residents to avoid driving through flooded roadways and to stay weather-aware through Saturday night.
