Weather Synopsis

After a warm start to the day, temperatures are cooling ever so slowly from west to east across the area as a weak frontal system pushes through.  The system is part of a splitting front, where most of the energry and moisture is headed into N California and Oregon.  The remanants of the northern branch will traverse the North Cascades tonight, bringing a period of moderate precipitation rates this evening and overnight.  The Washington Pass to Lake Chelan area could see upwards of 0.50" of water through Tuesday morning due to some upslope enhancement and a period of N-NE winds.  Snow levels should start higher on the east side of the Cascades this evening in the 5000-6000' range and then cool to around 3500' overnight.  Lighter amounts will be seen across the west slopes of the Cascades, except in the Mt Baker area where a period of moderate rain/mid-elevation snow will hang on through the evening hours. 

A weak trough will move the area on Tuesday, leaving us with a chance of showers and plenty of mid and high level clouds.  Snow levels will bump between 3500-4500'.  Upper level ridging will bring a period of drier weather Tuesday night and Wednesday.  However, offshore flow will increase later Tuesday night through Wednesday, with breezy to gusty E-SE winds developing near the Cascade Passes to the western Cascade foothills. Freezing levels will begin to rise on Wednesday, with the warmest temps and highest freezing levels realized the further west you travel from the Cascade crest.

Extended Weather Synopsis

We'll have weak ridging over our area Thursday and Friday with zonal flow and the storm track located well to our north over central B.C., and a cut-off low pressure well to our south into southern CA.  East flow will abate and we'll see high, dry and warm conditions to round out the end of the work week.  Freezing levels will be slightly cooler closer to the Canandian border over this period.  A more active pattern is likely to return early next week.

Previous forecast from Nov 16, 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’.
