Tulsa, Oklahoma – Relentless summer heat and daily thunderstorm chances will dominate Oklahoma’s weather starting Sunday, with a dangerous heat index nearing 105° in Tulsa and severe storm threats expected to follow.
According to the National Weather Service in Tulsa, Sunday’s high will hit 94°F, with heat index values reaching as high as 105°F by late afternoon. Scattered thunderstorms are expected before 10 a.m., followed by sunny skies and sweltering humidity. Residents along Highway 75, especially west of Tulsa, should take precautions by avoiding prolonged outdoor exposure and staying hydrated.
Localized showers and strong wind gusts may return Monday afternoon, with a 50% chance of thunderstorms and highs again near 91°F. A weak cold front could trigger stronger storm coverage Monday night into Tuesday. Heat index values will range from 95°F to 105°F throughout the week.
By Tuesday and Wednesday, storm chances decrease to 20–30%, but humid air remains locked in place, keeping temperatures high and heat risks elevated. Winds will shift gradually from south to east midweek, offering little relief from the oppressive pattern.
Looking ahead to the 4th of July, early indications show a 20% chance of storms Thursday night into Friday, with daytime highs in the mid-90s and continued humidity — a muggy backdrop for fireworks and festivities.
Prepare now: Charge devices, limit midday travel, and watch for further advisories from NWS Tulsa as conditions evolve.
