Weather Synopsis for Sunday & Monday
The second in our parade of frontal systems moves through our region this morning. The frontal boundary should push through the Cascades between 7 and 9 AM, changing steadier precipitation to showers. Moderate SSW winds gradually shift toward the WSW as the day progresses and the upper trough approaches. Expect 8-14" of snow for Mt Baker with 4-10" for Hurricane Ridge, the Mountain Loop, Paradise, Crystal, and Mt St Helens.
Snow showers continue as WSW winds shift back to the SW overnight with the trough over the region. The heaviest snow showers remain focused more on the volcanoes with light to moderate snow showers in other areas and some spillover to the east slopes of the Cascades. Snow levels drop from 3000 to around 2500 ft.
On Monday, a deep trough and associated cold front approach from the WNW. Decreased shower activity becomes more sustained moderate snowfall for the Olympics and the southern volcanoes as the front approaches. Snow levels should be in the 2500 ft range.
