Weather Synopsis
Operations Update: This is the last Mountain Weather Forecast of the 2025-26 season. NWAC will continue to monitor snow and weather conditions. Large storms and/or widespread avalanche cycles may cause us to issue special avalanche bulletins, avalanche warnings, or other spring statements. Mountain Weather Forecasts typically begin in mid-November for the winter season.
If you like sunshine and warm temperatures, you're in luck! We're wrapping up our weather forecasting season with a long stretch of warm and dry weather. A high pressure ridge has taken up residency over the Pacific Northwest and doesn't appear to be going away anytime soon. In general, each day should be fairly similar to the last, with only a few subtle changes.
Mostly clear skies Sunday night should allow snow surfaces to freeze in open areas, even as temperatures stay well above freezing. On Monday, 5000 ft temperatures easily climb into the low to mid 60s. Passing bands of high thin clouds won't do much to provide relief from the strong May sun. While the chance of showers and thunderstorms is less on Monday, there's still a slight possibility for convective precipitation to develop mainly in the southern forecast zones and near Mt Hood. While most locations won't see precipitation, keep your eyes on the sky. If dark, ominous clouds start to form, a thunderstorm could be heading your way.
Onshore flow Monday night may help draw slightly cooler air and a marine layer (clouds) into the lower elevations in the Olympics and west slopes of the Cascades. It's hard to say how far into the mountains any clouds will push. Higher in the terrain (5000 ft), diurnal temperature swings will once again allow nighttime lows to fall near 50 F. Temperatures quickly rebound on Tuesday, and any low clouds in the mountains retreat back to the coast. A passing disturbance to our east could spread a few more high and mid-level clouds over the area, primarily in the East North and East Central zones. But overall, it should be yet another warm, mostly sunny day in the mountains.
Enjoy the spring and summer! Mountain Weather Forecasts typically begin in mid-November for the winter season.

Extended Weather Synopsis
The high pressure ridge continues to control our weather through the remainder of the week. In general, each day will be very similar to the last. The biggest changes could be in the thickness and persistence of any overnight marine layer and ridgeline wind speeds. Overall expect mostly clear, mild nights followed by warm, sunny, dry days. The high pressure ridge flattens a bit on Wednesday, turning the upper air flow more westerly. This could be most noticeable with a change to more moderate ridgeline winds. However, our streak of dry, sunny weather doesn't seem to falter. When could we see a more substantial pattern shift? Good question. Most weather models don't hint at any meaningful change through at least next weekend.
