LITTLE ROCK, ARKANSAS — Arkansas residents are bracing for a dangerously hot Monday, June 29, 2026, as heat index values across nearly the entire state are forecast to climb well past 100 degrees by late afternoon, raising serious health concerns for anyone spending time outdoors.
Searcy is expected to see the highest reading in the state, with a heat index of 107 degrees. Wynne follows closely at 106, while Stuttgart, Helena, and Lake Village are all forecast to reach 105. Little Rock, Monticello, and Russellville are expected near 104 degrees, and Fort Smith is forecast at 103.
The danger isn’t limited to central and eastern Arkansas. Northern communities including Harrison, Mountain Home, and Clinton are expected to see heat index values near 99 to 100 degrees, while western Arkansas towns like Fayetteville and Mena are forecast slightly cooler at 95 to 97 degrees. De Queen and Texarkana, however, are expected to see some of the highest readings in the western part of the state, both topping 103 to 105 degrees.
Adding to the danger, western Arkansas is also expected to see breezy conditions Monday afternoon. While wind typically helps cool the body, when paired with extreme heat and humidity it can speed up moisture loss, raising the risk of dehydration and heat exhaustion faster than calm, humid air alone.
Health officials are urging Arkansans to take the heat seriously. With heat index values exceeding 100 degrees across virtually the entire state, residents are advised to stay hydrated, avoid strenuous outdoor activity during peak afternoon hours, and check in on elderly neighbors and family members throughout the day.
Anyone experiencing symptoms such as heavy sweating, dizziness, or a rapid pulse is urged to move to a cool location immediately and seek medical attention if symptoms do not improve.
