Pendleton, Ore. – Dangerous heat continues to scorch eastern Oregon this week, with triple-digit temperatures holding strong through Thursday evening. Residents face serious health and safety risks as the extreme heat lingers into the night.
According to the National Weather Service in Pendleton, an Extreme Heat Warning remains in effect until 8 p.m. Thursday for Pendleton, Hermiston, The Dalles, and surrounding Columbia Basin communities. Highs between 95 and 103 degrees are expected, with little overnight relief as lows stay near the mid-60s.
Heat-related illnesses rise sharply during extended events like this. Authorities urge residents to drink plenty of water, avoid outdoor work during peak afternoon hours, and never leave children or pets in vehicles. Employers and workers along U.S. Highway 395 and Interstate 84 should plan for frequent cooling breaks, as heat stress may occur quickly.
Thursday’s high in Pendleton is forecast to reach 98°F under widespread haze, with smoke from regional wildfires reducing visibility at times. By Friday, temperatures ease slightly into the mid-90s, offering some relief before showers move in this weekend.
The shift in pattern could impact outdoor events, including Friday night football, as scattered showers and clouds develop across Umatilla County. Residents should prepare for rapidly changing conditions and possible wet roads by Saturday evening.
Warnings remain in place through Thursday night, with updates expected as conditions change.
