PENDLETON – The eastern Oregon sky glows faintly silver at dawn, still and cold, with a thin fog brushing the fields outside town. The calm won’t last long. By Saturday, the region shifts sharply as a Pacific front barrels east, bringing rain, gusty winds, and the first true taste of November weather.
According to the National Weather Service in Pendleton, the quiet start gives way to increasing clouds and mild temperatures Friday before conditions deteriorate through Saturday afternoon. Rain spreads east of the Cascades by midday, turning steady and locally breezy with gusts reaching 30 mph along exposed ridges and the I-84 corridor.
Saturday will feel noticeably different — highs near 71°F before dropping sharply as the front clears. Though snow remains confined to higher elevations, cooler air behind the system signals the region’s transition toward early winter conditions. Light accumulations are possible across the Blue Mountains above 5,000 feet by late weekend.
Sunday promises a sharp recovery. Sunshine and calmer winds return, though highs retreat into the 50s. Another weaker front may bring showers back by Monday and Tuesday, continuing a damp pattern into early November.
Residents should prepare for slick roads and reduced visibility during Saturday’s heavier bursts of rain, particularly for travel between Pendleton, La Grande, and Baker City. Clearing gutters and checking headlights before the weekend’s storm could prevent mid-commute issues.
This Halloween weekend closes October with classic Pacific Northwest variety — fog, rain, wind, and a final burst of sunshine before the clocks fall back and November arrives in full swing.
