Eastern Oregon is in for a wet and unsettled start to the week, with showers and thunderstorms expected to affect Pendleton and surrounding areas from Monday through midweek. The incoming storm system could bring heavy rainfall, gusty winds, and small hail, making travel and outdoor plans a bit tricky for the next few days.
Storms Begin Monday with Thunder, Hail, and Gusty Winds
The National Weather Service in Pendleton has raised rain chances to 70% on Monday, especially after 11 a.m., with thunderstorms likely to develop later in the day—mainly after 5 p.m. Some of these storms may bring gusty winds and small hail, particularly in parts of Umatilla County and neighboring areas.
If you’re planning to be on the road Monday afternoon or evening, prepare for reduced visibility, slick roads, and slow-moving traffic during downpours. Lightning and hail may also pose brief hazards, especially for outdoor workers or events.
Rain Lingers Through Midweek with Cooler Days
The wet pattern continues into Tuesday and Wednesday, with widespread showers and cloudy skies keeping temperatures cooler. Daytime highs will stay in the mid-70s, while nighttime lows dip into the lower 50s, making for chilly mornings. You may also notice hazy conditions, especially in low-lying areas and valleys.
Winds will mostly remain light, but gusts may increase during thunderstorms. Commuters and school runs should account for longer travel times due to slippery roads and poor visibility during morning and evening showers.
Slight Improvement Late Week, But Showers May Return
By Thursday, the rain will begin to taper off, with just a slight chance of showers and improving sunshine. Temperatures will edge back up, reaching around 78°F, and continue climbing into the upper 70s by Friday, with some sun expected between passing clouds.
Although Friday looks drier, scattered showers could return by Saturday, so it’s a good idea to stay updated with the latest forecast if you have weekend plans.
