Weather Synopsis

A weak trough moved through the Cascades Saturday night. Scattered, generally light rain and snow showers continue along the west slopes of the Cascades. Shower activity could increase slightly in the afternoon. Spillover is expected to be limited to the immediate lee of the Cascade Crest on the east slopes of the Cascades. Expect partly cloudy skies or even full sunshine as you head further east. In most areas, temperatures started the day a few degrees warmer than on Saturday, with snow levels of 2500-3000 ft expected in the morning, rising around 3500 ft in the afternoon.

A broad ridge edges into the region Sunday night. Lingering rain and snow showers mostly taper for the west slopes of the Cascades during the evening hours, but clouds and some very light rain and snow move into northwest Washington Overnight as the next system approaches from the northwest.

Light rain and snow spread across the Olympics and into the Cascades Monday morning, becoming moderate for the west slopes of the Olympics, the mountain loop, and Mt Baker areas by the afternoon. Increasing moderate SSW winds associated with a modest barrier jet will also help wring out the rain around Mt Baker. Snow levels should start around 3000 ft, rising to 3500-4500 ft in the afternoon.

Previous forecast from Apr 6, 2024

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’.
