Pendleton, Ore. – The high plains around Pendleton shimmer silver at dawn as frost glazes pastures and parked trucks. It’s a crisp start to the week in eastern Oregon — the kind that makes coffee steam linger in the cold air. But this early chill won’t stick around long.
The National Weather Service in Pendleton reports patchy frost early Monday, with temperatures near the mid-30s before sunrise. By afternoon, the sun quickly takes over, pushing highs into the low 60s. Calm winds and clear skies will hold through Wednesday, creating ideal conditions for harvest work, road travel, and fall outdoor projects. Mornings will stay chilly, though, with lows hovering near freezing in sheltered valleys.
By Wednesday, temperatures warm slightly into the mid-60s under mostly sunny skies. The pattern begins to shift late Thursday, when Pacific moisture edges toward the Columbia Plateau. Clouds will increase Thursday night, and Friday brings the next chance for showers, possibly marking the first meaningful rain since early October. Winds may freshen slightly out of the west, but no strong gusts are expected.
Looking ahead to the weekend, Friday through Sunday could bring steady rain and cooler highs in the low 50s — a sign the winter transition season is beginning. For now, Pendleton enjoys two more days of calm before conditions turn damp.
Residents should take advantage of the mild start to prepare gardens and irrigation systems for colder weather. After all, Oregon’s first fall freeze is not far behind.
