Little Rock, Arkansas – Dangerous heat is gripping Arkansas today, with temperatures soaring into the upper 90s and heat index values pushing past 105° in many western and central areas. Travel and outdoor activities are increasingly risky as a Heat Advisory remains in effect for the Arkansas River Valley, stretching west of Little Rock and into northwest counties.
According to the National Weather Service in Little Rock, the most intense heat will persist through at least Tuesday, with maximum heat index values reaching 109° in cities like Russellville, Fort Smith, and Prescott. Residents are urged to limit outdoor exposure between 10 a.m. and 8 p.m., stay hydrated, and rely on air conditioning as fans may not be sufficient against these high temperatures.
Scattered thunderstorms will return by Sunday, continuing on and off through Thursday, mostly during afternoon and evening hours. While most storms will be isolated, some could bring locally heavy rain, dangerous cloud-to-ground lightning, and pockets of strong winds. Isolated flooding is possible where slow-moving storms deliver two to three inches of rain in a short period, especially in areas that see repeated downpours.
The combination of high heat and storm threats may cause travel delays, power disruptions, and hazardous conditions on area roadways. Check on neighbors, avoid strenuous work outdoors, and be ready for possible additional advisories as heat and storm impacts continue into next week.
