Weather Synopsis for Friday night through Sunday
A ridge transiting the region Friday night yields cloud-free skies and chilly temperatures, particularly for deep valleys east of the Cascades. ESE winds peak in the moderate range and will be heightened near mountain gaps and the west slope foothills. Freezing levels rise quickly on Saturday, topping out in the 7000-8500 ft range. Low clouds move into the Olympics mid-day and the west slopes of the Cascades late in the afternoon ahead of the next system. Light rain or high-elevation snow (above 6500-7000 ft) could develop late in the day for the southern Cascade volcanoes and Mt Hood. Although the easterly winds rapidly decrease during the morning hours, SSW Ridgeline winds increase into the moderate range for the Olympics and Mt Baker areas, likely becoming strong on exposed volcanoes late in the day.
On Saturday night, a front brings a frontal rain/snow band focusing moderate precipitation on Skagit and Watcom counties with lighter amounts elsewhere. The front also brings sharply cooler temperatures. By Sunday, Sunday as snow levels settle around 2500-3500 ft. Middle and upper elevations can expect storm total snowfall in the 3-9" for Skagit and Watcom counties, with generally lesser amounts elsewhere. The east slopes remain drier with less cloud cover, but moderate ridgeline winds may be impactful in the morning hours before gradually decreasing.
