Tulsa, Oklahoma – Thunderstorms are expected to build across Eastern Oklahoma Saturday afternoon, just as weekend plans take shape and summer heat intensifies.
According to the National Weather Service in Tulsa, scattered storms could develop after 1 p.m. Saturday, primarily along and north of Interstate 44. While most cells are expected to remain below severe limits, isolated strong winds and locally heavy rain could create hazardous travel near Tulsa, Broken Arrow, and Claremore. Spotter activation may be needed in some areas.
The weekend threat isn’t just storms — a steamy pattern continues with heat index values climbing as high as 103°F through Monday. NWS guidance indicates this prolonged humidity and heat may lead to dangerous conditions for outdoor workers, especially during peak afternoon hours.
Storm chances persist into Sunday, with a 30-40% chance of rain across the region each day. A frontal boundary expected by Monday night could bring wider coverage and heavier rainfall, especially Monday and Tuesday.
