Afternoon heat index values will reach up to 109 in the Advisory area and up to 112 in the Warning area.

Another hot and humid day on Sunday will lead to another heat advisory in effect for most of eastern Oklahoma and western Arkansas, running from noon to 7 pm Sunday. The lower Arkansas River Valley in W-C Arkansas will experience the most extreme heat Sunday and an Extreme Heat Warning has been issued from noon to 7 pm Sunday. Expect heat index values as high as 112F during the afternoon.

Heat stress will likely impact daytime outdoor activities through the next week. Drink plenty of water and take breaks in shade when spending time outdoors.

The prolonged hot and dry weather has led to worsening drought conditions across the region.

While still low, there are chances for showers and thunderstorms each afternoon this weekend. Rain amounts will not be enough to reverse recent drought trends. Gusty downburst winds will be the main threat.

An extended period of hot weather is likely to persist through at least the first part of September. The ongoing drought situation will worsen. Any rain chances remain low through the upcoming week.
