 With a clearing sky throughout the morning, our overnight low temperature is 72. We can expect more heat and humidity again on Friday. Sunny with a high 100 degrees, our heat index 104. Friday night's low 74, sunny and 102, breezy on Saturday. From the Ponca City Specialty Clinic Weather Center, I'm meteorologist Dan Holliday. Right now it's 77. What I know about courage, I learned from my adoptive mom. She said sometimes you just gotta hold on and know we'll get through this.
