The last organized weather disturbance in our recent pattern is currently crossing the Olympics this afternoon, and should spread another band of steady precipitation inland later this afternoon and evening. The trailing upper-level trough will focus shower activity on the Olympics, north and central Cascades tonight, and keep the winds in the moderate to locally strong range. With snow levels continuing to slide downwards overnight to 2000-2500', most locations will see an additional few inches of snow, with the higher end at 6-8" for the Mt Baker area.
A brief period of convergence should set up early Monday morning, focusing between Stevens and Snoqualmie Passes, adding another few inches to these areas. Shower activity will really taper into Monday afternoon with a break between weather systems. Mostly cloudy skies with sunbreaks should give way to partly sunny skies along the east slopes of the Cascades and on the eastern side of Mt Hood.
Snow levels will fall to around 1500' Monday night as we await the next storm. Light snow should develop over the Olympics and northern Cascades before daybreak, followed by moderate to heavy snowfall with strong to locally extreme west winds on Tuesday for the Olympics and Washington Cascades. The heavier precipitation may hold off for the Mt Hood area and the far southern WA Cascades. This will be predominantly a snow storm, but we should see a minor snow level rise into the 2500-3500' range from Mt Hood to Snoqualmie Pass ahead of the frontal passage Tuesday afternoon/early evening.

Extended Weather Synopsis
The good news doesn't stop there, and neither does the snow; we'll see two additional frontal systems arrive through Thursday, with snow levels well below Pass levels and many low-elevation trailheads. We'll be measuring storm totals in feet by the end of the day on Thursday. Expect a few rounds of strong westerly winds as well over the extended period.
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).
