Pendleton drivers could face hazy skies and reduced visibility through midweek as Oregon’s first week of fall leans hot and dry. The haze may impact travel along Interstate 84, especially during the Tuesday morning and evening commute. Residents should limit outdoor activity if sensitive to smoke or poor air quality.
According to the National Weather Service, widespread haze will linger across Pendleton through Wednesday morning, with highs climbing near 88 by afternoon. Winds will remain light, shifting from the north to the southeast, which could allow haze to pool in valleys. Clear skies are expected to return late Wednesday into Thursday, but the warm pattern continues.
Across Eastern Oregon, daytime highs remain well above seasonal averages, peaking at 85 on Thursday. Nights cool to the upper 40s and low 50s, offering some relief but signaling bigger seasonal changes. By Friday, Pendleton will dip closer to 76 degrees, setting the stage for a more fall-like weekend.
Travelers along I-84 should remain alert, as haze can create sudden pockets of low visibility in the early morning and late afternoon. Drivers are urged to use headlights and maintain safe following distances. Those planning outdoor events should also be mindful of poor air quality until midweek.
The upcoming week hints at stronger seasonal shifts. A chance of showers returns by Monday, a possible early signal of cooler fall weather arriving to the region.
