In Fairfax and, more broadly, across the state of Oklahoma: Clear skies will persist through the evening, with temperatures remaining very hot, ranging from 95 to 97 degrees Fahrenheit. Expect the heat to gradually cool off but still stay well above normal for this time of day. Winds will be moderate from the south, with speeds reaching up to 16 mph and gusts possibly hitting 33 mph, so there may be some breezy moments. No rain is expected overnight, so dry conditions will continue into the early morning hours. It’s a warm and clear evening, so if you're heading outdoors, stay hydrated and take precautions against the heat, especially if you'll be exposed for an extended period.
