Local Alert: Memorial Day Wind Advisory for Central Oregon; 45 MPH Gusts Tracked

CENTRAL OREGON — The National Weather Service in Pendleton has finalized details on a potent holiday weather system, keeping a Wind Advisory in effect for Central Oregon on Memorial Day. High Desert residents can expect tranquil conditions tonight before powerful tracking winds and a sharp drop in temperatures take hold for the holiday and early workweek.

Tonight & Memorial Day Morning Launch

If you are winding down your Sunday weekend plans, conditions will stay mostly clear and comfortable tonight. Overnight lows are expected to bottom out in the mid to upper 40s across Bend, Redmond, Prineville, and Madras. High desert valleys will see a light southwest breeze at 5 to 15 mph, with remaining evening gusts up to 25 mph tapering off before midnight.

Memorial Day morning will kick off with partly cloudy skies and comfortable outdoor conditions, making it an excellent window for early holiday services or outdoor morning walks. Temperatures will quickly climb into the upper 70s to lower 80s across the tri-county area, while valleys along the East Slopes of the Cascades—including Sisters, Sunriver, and La Pine—will see daytime highs reach the upper 60s to mid-70s.

High Wind Timing: Monday Afternoon & Night

The primary weather story begins midday Monday. The National Weather Service Wind Advisory runs officially from 11:00 AM to 11:00 PM PDT Monday.

While the morning begins with light south winds, a strong Pacific front will cause winds to shift to the southwest and intensify rapidly by Monday afternoon.

• Tri-County Valleys: Sustained southwest winds will jump to 15 to 25 mph, with gusts projected to top out around 45 mph.
• The Cascade Slopes & Passes: Higher elevations and exposed ridges will experience the brunt of the front, with localized gusts reaching up to 55 mph.
• Monday Night: The wind will not immediately drop when the sun goes down. Monday night remains windy with west winds ramping up to 20 to 30 mph and continued gusts around 45 mph through the evening hours.

Travelers towing trailers or operating high-profile vehicles along Highway 97 and Highway 20 are urged to prepare for sudden, heavy crosswinds. High-wind gusts will also create hazardous chop on the Cascade Lakes by Monday afternoon.

With Stage 1 Public Use Fire Restrictions active across the Deschutes National Forest, Ochoco National Forest, and BLM lands, these strong afternoon winds elevate fire safety concerns. Open campfires remain strictly illegal on public lands outside of developed campgrounds. Drivers should secure trailer chains to prevent roadside sparks and avoid parking idling vehicles over dry, unmanaged grass.

Midweek Reality Check: Tuesday Showers & Plunging Temperatures

The cold front begins pulling moisture into the region late Monday night, bringing a 50% chance of rain showers overnight as lows drop into the mid-30s and lower 40s.

Tuesday brings a total shift in the seasonal pattern, characterized by mostly cloudy skies, breezy northwest winds, and significantly cooler air:

• In the Valleys: Bend, Redmond, Madras, and Prineville face a 50% chance of rain showers and isolated thunderstorms, with daytime highs struggling to reach the upper 50s to lower 60s.
• Along the East Slopes: Conditions will be significantly wetter and colder. The NWS has placed a 70% chance of precipitation on communities like Sisters and La Pine, where rain showers and high mountain snow showers are likely. Highs will plummet into the lower 40s to low 50s.

A slight 20% chance of residual showers and thunderstorms lingers into Tuesday night and Wednesday morning before the High Desert begins a gradual clearing trend heading into the late week.
