Forecast Summary

Another hot and humid day leads to another heat advisory in effect for a good portion of eastern Oklahoma and the lower Arkansas River Valley areas, running from noon to 7 pm Friday. Expect heat index values as high as 108 during the afternoon.

Fayetteville, you're the one on the heater, having cracked the Top 5 in both categories this summer.

An extended period of hot and dry weather is likely to persist through at least the first part of September. The ongoing drought situation will worsen.
