Pendleton, Oregon – Residents in eastern Oregon should keep an eye on the sky as a slight chance of mountain showers and thunderstorms returns between 3 and 10 p.m. Tuesday and again on Thursday, with Pendleton and surrounding areas most at risk.
According to the National Weather Service in Pendleton, the probability of storms ranges from 15 to 25 percent for both days, focusing on higher terrain from The Dalles through La Grande, Baker City, John Day, and extending south into Burns and Ontario. Areas near the Oregon-Washington border, including Walla Walla and Hermiston, could also see brief downpours, gusty winds, and isolated lightning.
Travelers along I-84, US-395, and mountain passes like Cabbage Hill should be alert for sudden wet roads and reduced visibility between 3 and 10 p.m. each day. Local agencies recommend monitoring weather alerts, avoiding exposed ridgelines during storms, and delaying outdoor recreation until evening storms subside. Campers and hikers in the Blue Mountains and Wallowas are urged to have backup shelter and avoid high ground if thunder is heard.
This summer pattern is typical but can bring quick, localized hazards—especially for those working or traveling outdoors. The next detailed update is expected Thursday morning, with additional advisories possible if storm activity increases.
