 From Little Rock Public Radio, I'm Nathan Treece. It's 79 degrees with fair skies in Little Rock at this hour. We have an excessive heat warning in effect today and for the July 4th holiday until 9 p.m. Heat index for both days may rise to 115 degrees. If you're planning any outdoor activities, have an air-conditioned space nearby, have plenty of water on hand, and keep an eye out for early signs of heat exhaustion. It's 643.
