DISCUSSION: As a weak low pressure system gradually pushes through portions of central-to-northern California, a decent amount of moisture will continue to track eastward across portions of central-to-eastern Washington state. As this moisture moves across some of the higher elevated regions with the aforementioned parts of Washington, there will an increased likelihood of light "advisory-level" snowfall totals across this part of the nation during the day on Sunday. Having said that, although this will be a more minor snowfall event at best, it is still best to remain off the roads during the time in which the snowfall is falling at its heaviest. Thus, eliminating the largest threat for spin-outs, accidents, etc.
