Weather Synopsis

This upcoming week would seem exceptionally wet and stormy if it weren't for the extradorinarly wet weather our region experienced last week.  Another atmospheric river will make headway into the Olympics and northern Cascades tonight, and fill in over the area on Monday.  The heaviest precipitation will likely be focused on the central and north Cascades, although everyone will get in the action.

Snow levels will start high and stay high through Monday afternoon. The one execption will be the East North zone including Washington Pass, where it's likely snow levels will stick around 6000' until mild air blasts in on SW winds mid-day/afternoon.  1-2 inches of precipitation will fall near the Cascade crest and along the west slopes of the Cascades during the day.  There will be east flow through the Passes initially tonight, but it won't make a difference as far as snow levels are concerned without our usual cold air pool on the east side of the state. Strong W-SW winds will become extreme later tonight through Monday.  Extreme west winds will linger into Monday evening along the east slopes of the Cascades.   

As the first moisture wave passes through Monday night, we'll see a cooling trend with snow levels falling to 3500' in the north and 5500' in the south.  Snow will accumulate at mid elevations and there should be a few hours of convergence that enhances snowfall in Whatcom/Skagit county Cascades Monday night, but likely stays north of Stevens Pass. 

The cool down will be short lived as another impulse slides through on Tuesday, and with it another rise in snow levels.  This doesn't look to be quite as warm as Monday, but we should see snow levels shoot back up well above the major Passes.

Extended Weather Synopsis

A strong front will bring stormy conditions and eventually falling snow levels overnight into early Wednesday morning, followed by moderate snow showers along the west slopes and Passes of the Cascades on Wednesday.  Total precipitation looks to be in the 4-7" range of water equivalent through Wednesday afternoon, with the highest totals in the West North/West Central and Olympic zones.  We'll see additional systems to round out the work week and although we'll be cooler, we should see brief warm-ups with each weather system.

Previous forecast from Dec 14, 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’.
