Weather Synopsis
THIS IS NOT A REAL FORECAST. THIS IS USED FOR TESTING PURPOSES ONLY! NWAC NOR RACHEL IS NOT RESPONSIBLE FOR YOU NOT READING THIS FIRST LINE AND THINKING THIS IS REAL.
The much-needed snow accumulation pattern continues across the Pacific Northwest as a cool upper-level trough combines with moist WSW winds and an unstable atmosphere. As that moist, unstable air hits the mountains, it triggers moderate to locally heavy snow showers on the windward slopes, with enough wind to push some moisture over the Cascade Crest. More sustained, intense precipitation is possible at times, especially in convergence zones targeting Mt. Baker, the Mountain Loop, and Stevens Pass. These bands of convergence are more likely associated with more organized "comma clouds." The first is passing late Friday and is likely to trigger an uptick in snow showers Friday evening.
As the weekend progresses, a trough amplifies offshore, and winds turn more southwesterly. This nudges the precipitation focus slightly northward. As a result, snowfall decreases on Mt. Hood but increases in the Olympics and at Mt. Baker. A more organized system approaching late Sunday should bring some more sustained snowfall to the region during the mid-day and afternoon hours.
Through the weekend, expect 1-3 feet of low-density snow in areas near and west of the Cascade Crest, with lighter totals of 4-8 inches at Blewett Pass and Mission Ridge. Snow levels should be in the 1000-2500 ft range through Saturday morning, then rise 500 ft or so from Saturday morning onward in areas west of the Cascade Crest. The east slopes and passes should stay cooler as light E pass-level winds develop Saturday night.

Snow and Freezing Level (ft)
The snow level forecast represents the general snow level over a 6 hr time period. Snow level is defined as the elevation that snow begins to accumulate on natural surfaces. Snow may accumulate even when the surface temperature is slightly above freezing. Freezing levels are forecast when precipitation is not expected. Freezing levels often drop rapidly with the onset of precipitation. During periods with temperature inversions, there may be multiple freezing levels. We forecast the freezing level that most users will experience in the mountains.

Ridgeline Winds (mph)
Ridgeline winds represent the average wind speed and direction over a 6 hr time period. The wind forecast represents an elevation range versus a single elevation. The elevation range overlaps with the middle and upper elevation bands in the avalanche forecast and differs per zone. Wind direction () is the direction the wind is blowing from, given in degrees or cardinal direction on a 16 pt compass rose. Ex: A west (W) wind blows east (E).

Precipitation and Snow (in)
Precipitation: Water Equivalent (WE) is the liquid water equivalent of all precipitation types; rain, snow, ice pellets, etc. and forecast to the hundredth of an inch at specific locations. Snow: Forecast at the same locations as precipitation but at 5,000’ in elevation. Snow forecasts are to the nearest whole inch and presented in a range.

Snow and Freezing Level (ft)
The snow level forecast represents the general snow level over a 6 hr time period. Snow level is defined as the elevation that snow begins to accumulate on natural surfaces. Snow may accumulate even when the surface temperature is slightly above freezing. Freezing levels are forecast when precipitation is not expected. Freezing levels often drop rapidly with the onset of precipitation. During periods with temperature inversions, there may be multiple freezing levels. We forecast the freezing level that most users will experience in the mountains.

Ridgeline Winds (mph)
Ridgeline winds represent the average wind speed and direction over a 6 hr time period. The wind forecast represents an elevation range versus a single elevation. The elevation range overlaps with the middle and upper elevation bands in the avalanche forecast and differs per zone. Wind direction () is the direction the wind is blowing from, given in degrees or cardinal direction on a 16 pt compass rose. Ex: A west (W) wind blows east (E).
