Pendleton, Oregon – Residents in eastern Oregon should stay alert as a slight chance of mountain showers and thunderstorms returns on Tuesday, with Pendleton and surrounding areas most at risk. The storms are expected between 3 and 10 p.m. on both Tuesday and Thursday.
According to the National Weather Service in Pendleton, the probability of storms ranges from 15% to 25% for both days, particularly affecting 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 experience brief downpours, gusty winds, and isolated lightning.
Travelers along I-84, US-395, and mountain passes like Cabbage Hill should be prepared 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 the storms pass. Campers and hikers in the Blue Mountains and Wallowas are advised to have backup shelter and avoid high ground if they hear thunder.
This typical summer pattern can bring quick, localized hazards, especially for those working or traveling outdoors. The next detailed update is expected on Thursday morning, with additional advisories possible if storm activity intensifies. Stay weather-aware to stay safe.
