 News from the Radio Oklahoma News Network. I'm Dale Forbis. A heat advisory is in effect for Oklahoma through 9 p.m. tonight. The National Weather Service issued that advisory for most of the state. Recommendations, drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, wear lightweight and loose-fitting clothing. Former Oklahoma City Mayor Ron Norrick says he remembers the reaction to one of his MAPS projects.
