Oregon — A dim gray glow spreads over the Blue Mountains as early clouds drift low and steady above Pendleton. The air feels cool and still, and damp pavement reflects the first hints of thicker moisture creeping in from the southwest. These subtle signals point to a slow-building, unsettled stretch that could affect early Thanksgiving travel across Eastern Oregon and I-84.

Residents should plan for shifting road conditions beginning late Sunday. Light rain may start gradually but spreads quickly once deeper moisture arrives. Travelers heading toward La Grande or Hermiston may encounter slick pavement first, especially during the early morning and early evening windows. It’s wise to check headlights, keep wipers clean, and allow a few extra minutes during Monday’s commute.

For now, today stays mostly dry. Clouds dominate the morning sky, but south winds remain gentle and temperatures lift into the lower 60s—unseasonably mild for mid-November. To be fair, the quiet weather is only temporary. Models hint at an early Winter Tease with cooler nights and strengthening moisture pushing inland.

Rain chances climb Sunday afternoon. The first showers remain light, yet drizzle could linger long enough to reduce visibility and dampen travel plans. By Sunday night, steadier rain becomes more likely, with up to a tenth of an inch possible. Winds stay calm, but higher ridges east of town may see breezier conditions as moisture deepens.

Monday continues the wet start. Showers are likely before midday, and roads may feel slower during the busiest commuter hours. Though temperatures stay above freezing, a warm-to-cool shift later in the week could eventually open the door for early-season snow chances in the mountains—something to watch as Thanksgiving approaches.
