Oregon – Misty rain streaks across car hoods in Pendleton late this morning, and the steady breeze already hints at the stronger winds approaching the Columbia Basin. Pavement glistens along I-84, and low clouds hang over the Blue Mountains as Eastern Oregon enters a turbulent midweek weather stretch fueled by a strengthening Pacific system.
According to the National Weather Service, a High Wind Watch goes into effect Tuesday evening and continues through Wednesday afternoon. Southwest winds will intensify quickly, rising to 25–35 mph, with gusts of 55–60 mph possible in and around Pendleton. The strongest bursts are expected overnight Tuesday into early Wednesday, especially in open terrain and foothill communities. Damaging winds could topple tree limbs, down power lines, and create difficult travel for high-profile vehicles.
Rain continues through the day with temperatures hovering in the upper 40s. Light rain remains possible tonight, followed by a brief lull Tuesday morning. Clouds then rebuild as the incoming storm reorganizes over the Pacific Northwest. By late Tuesday, breezy conditions strengthen, and gusty winds return as the next wave of moisture arrives. Drivers should plan for reduced visibility, sharp gusts along the I-84 corridor, and sudden shifts in steering on exposed bridges.
Wednesday brings the most active period, with strong winds and highs near 50. A rain-snow mix may develop in the mountains as snow levels fall to near 2700 feet Wednesday night, creating early-season winter driving concerns for Christmas-travel planners heading toward the passes.
