Weather Synopsis

Bands of moderate to locally heavy precipitation continue to focus on the Mountain Loop, Snoqualmie Pass, the West South, and Mount Hood, with a rain/snow line somewhere in the neighborhood of 3500-4000ft. Winds are strong down south, but quite light north of I-90. Precipitation diminishes in both distribution and intensity this evening and overnight, while areas north and east see some partial clearing. Any lingering showers should come to a close Tuesday morning as a quick and transient ridge pushes ashore and east flow starts to take root in the afternoon. Many mountain locations may even see some sun breaks with light to moderate winds and mild temperatures. This dry weather will be short-lived as the next system pushes ashore Tuesday night into Wednesday morning. Expect another round of widespread precipitation on Wednesday, with snow levels starting around 1500-2000ft and rising to 3000ft by Wednesday night. It’s a quick hitter with the heaviest precipitation beginning to taper Wednesday late in the afternoon/evening.

Extended Weather Synopsis

Some post-frontal showers may linger on Thursday, while many other mountain locations begin to clear. Another quick ridge of high pressure builds by the afternoon and keeps things dry and relatively calm. Another significant system begins to knock on the door Friday evening and is with us over the weekend. More details to come on that, but as of now, it looks warm.

Previous forecast from Feb 17, 2025

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’.
