Little Rock, Arkansas – Blistering heat returns across Arkansas Friday with dangerously high heat index values climbing as high as 104°F in parts of central and eastern regions. A Heat Advisory remains in effect through 9 p.m. Friday, with state officials urging residents, particularly in the Little Rock area, to avoid extended outdoor activity.

According to the National Weather Service in Little Rock, temperatures will peak near 96°F on Friday, with high humidity creating triple-digit feels-like conditions. This pattern threatens heat illnesses, especially for those working or traveling along I-40 or exposed areas across Pulaski, Saline, Garland, and Faulkner counties.

To stay safe, drink plenty of fluids, wear light clothing, and seek air-conditioned spaces during peak afternoon hours. Employers should stagger outdoor work shifts and ensure shaded breaks. Check on neighbors, the elderly, and those without reliable cooling.

Weekend weather offers little relief. Highs will remain in the mid-to-upper 90s through Sunday, with only a slight chance of afternoon storms Saturday and Sunday. Relief could arrive Monday night into Tuesday, as a cold front pushes into northern Arkansas, increasing thunderstorm chances.

Warnings remain in effect through Friday night, with additional advisories possible if the front delays. Stay informed through NWS updates or emergency management alerts.
