Hot weather continues Saturday with a Heat Advisory in effect for much of eastern Oklahoma and west central Arkansas. Afternoon heat index values will reach up to 109 in the advisory area.
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 storms each afternoon over the 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 and dry weather is likely to persist through at least the first part of September. The ongoing drought situation will worsen. Isolated afternoon showers and storms are possible this weekend.
