Pendleton, OR – Wet roads and gusty winds mark the end of the holiday weekend across eastern Oregon, but calmer, cooler air is on the way. After steady showers through Columbus Day, drier skies and a crisp fall pattern will settle over Pendleton and surrounding Umatilla County early this week.
According to the National Weather Service in Pendleton, periods of rain will continue Monday with highs in the mid-50s before tapering by nightfall. Drivers along I-84 and U.S. 395 should expect slick pavement and reduced visibility during passing showers Monday afternoon. The system clears out by early Tuesday, opening the door to mostly sunny skies and a modest cooldown.
Tuesday morning may start cool, with lows near freezing in rural valleys and patchy frost possible west of town. Residents are urged to protect garden plants and outdoor plumbing as temperatures dip. By midweek, stronger sunshine and light winds will return, offering prime conditions for pumpkin patches, harvest events, and fall leaf outings.
The week ends on a bright note, with highs climbing back into the low 80s by Friday under mostly sunny skies. Morning commuters and school buses will enjoy drier roads and crisp air — a classic mid-October rebound after the early-week showers.
