Pendleton, Oregon – Unseasonably warm weather will hit Eastern Oregon Thursday with highs reaching 85°F in Pendleton, but the spring heat won’t last long.
According to the National Weather Service, a sharp pattern change arrives late Friday, bringing increasing cloud cover, a 40% chance of rain by Friday night, and a 70% likelihood of showers Saturday. The back-to-back shift from summer-like sun to weekend storms could impact travel across US-395 and local routes, especially near Pendleton, Umatilla, and surrounding areas.
Drivers should plan for dry roads Thursday and early Friday but remain alert for slick conditions developing late Friday night into Saturday. Outdoor plans and local events may be disrupted as scattered showers roll in and highs dip back into the low 60s by Saturday. Wind speeds remain light this week, offering some relief from blowing dust or fire concerns, but rapidly changing temperatures may increase fatigue or dehydration for those working or recreating outside.
Friday still offers mostly sunny skies and highs in the mid-80s before clouds increase during the evening. Saturday will be the most active day, with showers likely through the morning and a chance of continued rain by afternoon.
Here’s the 5-day spring forecast:
- Thursday: Sunny, high near 85°F
- Friday: Mostly sunny, high near 85°F
- Saturday: Showers likely, high near 62°F
- Sunday: Mostly sunny, high near 66°F
- Monday: Sunny, high near 73°F
