 From Little Rock Public Radio, I'm Nathan Treese. It is 80 degrees with fair skies in Little Rock at this hour. Another day of extreme heat here in Arkansas as heat index values will be upwards of 112 degrees today. Tomorrow night, a cold front will sweep through the state, bringing with it likely storms and rain, but cooler temperatures through the end of the week, ranging from the mid to high 80s. It's 643. You're listening to Morning Edition here on Little Rock Public Radio. Good morning.
