Weather Synopsis

An upper-level front has moved inland this afternoon, bringing light rain and mountain snow to the west side of the Cascades. Precipitation will continue and intensify through the early evening, with cooler temperatures lowering snow levels below the mountain passes. This system will be relatively short-lived, with precipitation tapering off quickly overnight. A Puget Sound Convergence Zone is expected to develop this evening near or just south of Snoqualmie Pass, prolonging rain and mountain snow in those areas with locally higher intensity. By Monday morning, most areas will be drying, with a chance of very light lingering showers along the west side of the Cascades, mainly north of I-90.

High pressure will build in behind the system, bringing drier conditions through Tuesday. Most of the cloud cover will clear out overnight into Monday, with low-level clouds lingering in the northwest Cascades and east of the Crest. For the rest of the region, Monday will begin mostly clear, with thin high clouds increasing later in the day.

The cooling temperatures will persist into Monday, and freezing levels are expected to dip below 1000' first thing in the morning. As the sun comes out, temperatures will climb, but remain fairly cool for this time of year. Ridgeline winds ease on Monday with NW flow aloft, shifting easterly through the mountain passes in the afternoon.

Dry weather will continue into Tuesday, with cool overnight temperatures and high clouds hanging over the region.

Extended Weather Synopsis

A more powerful storm system positioned NW of Washington will enter the region on Wednesday morning. This system may stall offshore on Wednesday, extending the precipitation into Thursday morning before pushing east. Snow levels don't appear particularly low, but middle and upper elevations will likely get a healthy dose of snowfall.

Previous forecast from Mar 29, 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’.
