 1023 KRMG has Tulsa's most accurate and dependable forecast. Heat and humidity slowly building. The heat index by Sunday topping 105. Now, one or two of us could see an isolated sprinkle or shower as we roll through the rest of the day, mainly to the north of Tulsa. And then the heat, triple-digit heat through Wednesday. We will see a slight cool down and some shower chances starting on Thursday. I'm Chief Meteorologist James Edelott for Fox 23 and 1023 KRMG Tulsa's News and Talk.
