A moderately deep low tracking toward the northern end of Vancouver Island will bring stormy weather to the Pacific Northwest through Wednesday.
Clouds gradually lower thicken Monday night, with SW winds increasing. In most areas, these winds remain light, but push into the moderate range for Mt Hood, the Olympics, and Mt Baker areas. A warm front spreads precipitation into the mountains in the early morning hours on Tuesday, starting with the Olympics, Mt Baker, the Mountain Loop, and Mt Rainier areas. A brief period of low-level SE winds will favor the Olympics during this time period, when precipitation likely starts with snow levels around 3000 ft. Snow levels quickly rise with a warm frontal passage on Tuesday morning, changing snow to rain as it spreads throughout the region. Expect moderate to occasionally heavy rain and high-elevation snow throughout areas near and west of the Cascade Crest, with low-level E winds providing plenty of spillover onto the east slopes of the Cascades. The heaviest precipitation shifts from the northern Cascades to the southern Cascades as the day progresses.
The cold front likely crosses the Olympics at the end of the day, then progresses through the Cascades in the evening, initiating cooling and a drying trend. Rain and snow showers will generally be light on Tuesday night, but convergence enhancement will favor the Mt Baker area for moderate intensities. Convergence shifts south as the upper trough approaches on Wednesday, with more vigorous snowshower activity across the region and snow levels dropping below 2500 ft. Convergence is likely to reach the vicinity of Stevens Pass later in the day and could bring intense snowfall at times.

Extended Weather Synopsis
Snow showers and convergence ease and lift northward on Wednesday night with very light snow showers lingering on Thursday as a ridge moves into the area and expands with rising freezing levels through Friday.
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).
