Oklahoma City is starting Thursday clear and in the mid-70s, but the thermometer is headed for another near-100-degree afternoon. The high is expected to reach 99, with mostly clear skies and generally light south-southeasterly winds. The bigger story is that this stretch of late-summer heat is not leaving quietly: heat is expected to persist through Saturday.

The National Weather Service office in Norman says elevated fire danger will persist through at least Saturday. Oklahoma City has a 10% chance of rain Thursday, followed by a 0% chance Friday, while no distinct Saturday daytime precipitation probability is provided.

Persistent Heat Holds Through Saturday

Thursday night will stay mostly clear, with low temperatures in the mid to upper 70s. Friday brings another day with a high of 98 degrees, and Saturday is expected to remain hot.

Residents planning outdoor work or activities should consider the cooler morning and evening hours, drink plenty of water and take breaks from the heat. The combination of hot temperatures, dry conditions and wind can also make grass and brush fires spread more easily, so extra care with outdoor flames and sparks will be important.

Storm Chances Return Sunday

The pattern finally shifts Sunday, when rain and storm chances rise. Sunday is expected to remain hot, with storm chances continuing into the night.

The broader region could see strong to severe thunderstorms Sunday afternoon and evening, with large hail and gusty winds possible, particularly across northern Oklahoma. Storm chances continue Monday, while temperatures should turn cooler.

Cooler, Wetter Pattern Lingers Into Next Week

The week ahead is expected to remain cooler and more unsettled than the hot stretch arriving first.
