Weather Synopsis

Our cool snow showery pattern will continue through Tuesday.  After that, buckle up as a series of strong storms impacts the PNW for several days starting late Tuesday night. Before more powerful storms arrives, we'll see snow showers continue Monday night through Tuesday.  Another convergence zone will take shape this evening, sticking near the Whatcom/Skagit line this evening and likely drifting south toward Hwy 2 overnight.  Another 4-9" is likely in the convergence bands, with a few inches for other areas along the west slopes, Passes and Mt Hood, and an inch or so along the east slopes. Snow levels will flirt with sea-level overnight, so even though the water numbers aren't eye-popping, low-density snowfall will stack up for what does fall out of the sky. 

Shower activity should be lighter Tuesday morning before a new upper level feature arrives in WNW flow aloft and increases general shower activity in the afternoon.  Light, scattered showers will become steady precipitation on Tuesday night as warm frontal moisture moves into the area. The timing of steadier, heavier precipitation is uncertain on Tuesday night, but Mt Hood may see stormy conditions develop rapidly overnight. 

A powerful frontal system will impact the area on Wednesday. After a cool start to the storm, a warm front will push into the central Cascades, and wherever this boundary sets up, we'll see snow levels rise to 3500-4500' with heavy precipitation. Further to the north, snow levels will be slower to rise and precipitation will likely not be as intense. Winds will begin to crank up, becoming extreme above treeline and higher peaks.

Extended Weather Synopsis

The jet stream will lift north on Wednesday, becoming centered around the WA/BC border as it directs a series of storms and moisture into our region for several days.  There will be a tight north/south temperature gradient, meaning cooler snow levels will be found near the Canadian border with milder snow levels (4500-6500') near the Columbia River, with a battleground between cooler and milder snow levels for areas in between.  The details are fair from certain, but initial 3-day precipitation totals Wed-Fri could be in the 3"-8" of water(!) range.  Expect stormy conditions over this time with strong to extreme winds.

Previous forecast from Mar 9, 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’.
