...A Heat Advisory in effect for Southeast Oklahoma and parts of Southwest Arkansas and Northeast Texas through 6 PM CDT with heat indices near 105 degrees or slightly higher... The combination of more cloud cover and higher chances for showers and thunderstorms will contain the hot temperatures for much of the Four State Region and allow for lower heat indices than of recent days. Be sure to drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives, neighbors, and pets.
Scattered showers and thunderstorms will gradually decrease in coverage and intensity this evening. However, additional showers and storms will begin developing overnight along and south of a frontal boundary sagging south toward the Red River Valley. Expect more widespread showers and storms on Monday with high temperatures in the upper 80s to around 90 degrees over much of the region.
... A Heat Advisory will be in effect until 6 PM CDT for Southeast Oklahoma and parts of Southwest Arkansas and Northeast Texas... Expect another humid day across the Four State Region with scattered showers and thunderstorms and cloud cover helping contain the hot daytime temperatures for much of the area. Northwest sections of the region with less cloud cover and rain chances will see the hotter readings and heat indices. The humid conditions will continue overnight with convection decreasing with loss of heating with low temperatures in the middle to upper seventies.
