Weather Synopsis

It’s another beautiful, sunny day across the Pacific Northwest, with the region still in an extended stretch of dry weather. Temperatures are generally in the mid-40s °F at 5,000 feet, with light winds and scattered clouds building over the Cascade Crest. Wind directions are quite variable, with mountain passes shifting east–west and ridgelines mostly trending N or NE.

Skies will stay mostly clear overnight, while low-level clouds develop along the coast and push into Puget Sound. A weak disturbance approaching the region will start to bring some changes on Monday, beginning with increasing cloud cover through the day. Areas near the Crest should turn partly to mostly cloudy by Monday evening. Ridgeline winds will trend toward moderate speeds in the afternoon as upper-level flow turns westerly.

As clouds increase, there’s a chance of isolated rain and high-elevation snow along the western slopes and around Mt. Hood, but any precipitation will be brief and spotty. Cloud cover will continue Monday night into Tuesday, with an increasing chance of rain and snow. Snow levels should remain relatively steady near 5,000 feet.

Recent guidance has reduced the total precipitation for this system, with the bulk of the moisture focused near Mt. Baker and the West Central zone. At best, these areas could see up to about 0.1 inches of water by Tuesday evening. Southern zones will see significantly less, likely just some light rain or snow, Monday night into Tuesday.

Previous forecast from Apr 25, 2026

The NWAC program is administered by the USDA-Forest Service and operates from the National Weather Service Forecast Office in Seattle. NWAC services are made possible by important collaboration and support from a wide variety of federal, state and private cooperators.

The 5000’ temperature forecast does not imply a trend over the 12 hr period and only represents the max and min temperatures within a 12 hr period in the zone. The 6-hr snow level forecast, the forecast discussion, and weather forecast sections may add detail regarding temperature trends.

The snow level forecast represents the general snow level over a 6 hr time period. Freezing levels are forecast when precipitation is not expected.

*Easterly or offshore flow is highlighted with an asterisk when we expect relatively cool east winds in the major Cascade Passes. Easterly flow will often lead to temperature inversions and is a key variable for forecasting precipitation type in the Cascade Passes. Strong easterly flow events can affect terrain on a more regional scale.

Ridgeline winds are the average wind speed and direction over a 6 hr time period.

The wind forecast represents an elevation range instead of a single elevation slice. The elevation range overlaps with the near and above treeline elevation bands in the avalanche forecast and differs per zone.

Wind direction indicates the direction the wind originates or comes from on the 16-point compass rose.

Water Equivalent (WE) is the liquid water equivalent of all precipitation types; rain, snow, ice pellets, etc., forecast to the hundredth of an inch at specific locations. To use WE as a proxy for snowfall amounts, start with a snow to water ratio of 10:1 (10 inches of snow = 1 inch WE). Temperatures at or near freezing will generally have a lower ratio (heavy wet snow) and very cold temperatures can have a much higher ratio (dry fluffy snow).

The label LT, is shorthand for ‘less than’.
