According to the National Weather Service in Pendleton, a 50% chance of showers and thunderstorms arrives Tuesday, September 9, lasting into the night. Highs will reach the upper 70s, but cooler air follows with temperatures dropping into the lower 50s overnight. Officials urge residents to prepare for sudden downpours, charge devices in case of power outages, and avoid unnecessary travel during the most active storm periods.
