Oregon – Sunshine quickly warms Pendleton this morning, and by early afternoon, temperatures climb into the mid-70s, giving eastern Oregon a brief stretch of spring warmth before a cooler, unsettled pattern moves in by Friday night. The air feels calm now, but change is already developing.
According to the National Weather Service, Pendleton will reach near 73°F today and 75°F Thursday under mostly sunny to partly cloudy skies. By Friday, highs remain mild near 74°F, but increasing clouds and shifting winds signal an approaching system. A slight chance of rain develops late Friday, continuing into early Saturday.
Across Umatilla County, including Hermiston and Milton-Freewater, outdoor conditions stay favorable through Thursday. However, winds could gust up to 18 mph Friday afternoon, especially along open stretches of I-84, creating crosswind concerns for high-profile vehicles.
Travel impacts increase heading into Friday night as rain chances return. Roads that stayed dry all week may turn slick quickly. Plan extra time if traveling late Friday or early Saturday. Early mornings remain cool, starting in the 40s, so layers are still necessary.
The cooldown becomes more noticeable Saturday, with highs dropping into the mid-50s before rebounding slightly by Sunday under clearer skies. Drier weather returns briefly, though additional rain chances may develop early next week.
Five Day Outlook for Pendleton, Oregon:
Thursday: Mostly cloudy, high near 75°F.
Friday: Mostly cloudy, high near 74°F.
Saturday: Slight chance of rain, high near 56°F.
