Tulsa, Oklahoma – Low clouds are breaking apart across eastern Oklahoma, but a much more active weather pattern is already taking shape beyond the horizon. The calm conditions visible around Tulsa this afternoon won’t last long.
Drivers traveling along I-44, US-75, and the Creek Turnpike should take advantage of the quieter weather while it lasts. Conditions are expected to change quickly heading into Sunday night as thunderstorms develop across eastern Oklahoma.
According to the National Weather Service in Tulsa, patchy fog early Sunday gives way to increasing heat and humidity. Temperatures will surge into the lower 90s across Tulsa, while heat index values could climb as high as 106 degrees during the afternoon.
The larger weather pattern across the Plains and Midwest supports increasing thunderstorm activity through early next week. Meteorologists are tracking a slow-moving frontal boundary that may trigger multiple rounds of storms across northeastern Oklahoma and northwestern Arkansas.
Sunday night carries the greatest immediate concern. Rain chances reach 90%, with thunderstorms expected to develop and spread across the region. Some storms could produce damaging wind gusts, while repeated rounds of rainfall may create localized flooding concerns in low-lying and poor-drainage areas.
Plan outdoor activities early Sunday. Conditions may deteriorate rapidly after sunset. While tornado potential remains limited, forecasters continue monitoring stronger storm clusters capable of producing severe weather and heavy rainfall.
The unsettled pattern continues into Monday with additional showers and thunderstorms likely. Rain chances remain elevated through Tuesday and Wednesday as the frontal boundary lingers nearby. Daily storm opportunities could affect commutes, outdoor work, and summer recreation across Green Country.
Looking ahead, temperatures may trend above normal later next week once this storm pattern weakens. For now, heat, humidity, and repeated thunderstorm chances remain the primary concerns.
