PENDLETON, Ore. – Clear skies and mild fall sunshine will dominate eastern Oregon as the new week begins, bringing ideal conditions for travel, outdoor projects, and early Halloween decorating. Mornings will start brisk in the upper 30s, but afternoons will warm comfortably into the low to mid-70s through Thursday.
According to the National Weather Service in Pendleton, calm high-pressure air will keep skies mostly clear and winds light along the I-84 corridor. Residents can expect light morning chill followed by warm, dry afternoons — excellent news for those visiting local pumpkin patches, farmers markets, and area parks. Drivers along I-84 and U.S. 395 should see no weather-related issues through midweek.
Daytime highs will gradually climb to around 75°F on Tuesday before easing slightly midweek. Nights will dip into the 30s and low 40s, so gardeners should cover sensitive plants and bring potted flowers indoors. The pattern will hold stable, with only a slight chance of clouds or isolated sprinkles by late Friday into Saturday as a weak Pacific system brushes the region.
For those planning early fall hikes or scenic drives toward the Blue Mountains, pack layers. Even with bright sunshine, morning and evening temperatures can feel sharply cooler. Keep an eye on NWS updates as a cooler pattern could develop later next weekend.
