PENDLETON, Ore. – Frost sparkled on rooftops and fence lines across the Umatilla Basin this morning as temperatures hovered near freezing. The air was calm and crisp, a quiet November chill settling over the fields before the day warms. Light patchy fog formed in low-lying valleys near Hermiston and along I-84, making for slow starts and icy windshields across eastern Oregon.
According to the National Weather Service in Pendleton, clear skies will dominate through the weekend, allowing for wide temperature swings — chilly mornings in the 30s giving way to mild, sunny afternoons in the upper 50s and 60s. By Monday, high pressure brings an even warmer push, with highs near 64°F before another shift midweek.
Drivers heading east toward La Grande or north toward Walla Walla should remain alert for fog in shaded areas through midmorning. The cold air will lift quickly after sunrise, offering excellent late-fall weather for outdoor cleanup or early holiday decorating. Winds stay light and variable through Monday, keeping travel conditions calm.
Veterans Day looks mostly sunny but cooler, with highs back near 60°F before a cloudier stretch midweek. Models hint at a more unsettled pattern late Wednesday into Thursday, when the first light rain could brush eastern Oregon — a signal that the Pacific storm track may be reawakening just in time for pre-Thanksgiving travel planning.
Residents can expect a classic early-November pattern: frosty mornings, bright afternoons, and a subtle tease of winter ahead. Dress in layers, enjoy the weekend warmth, and keep an eye out for that next round of Pacific moisture forming offshore.
