A cold and showery air mass will spread across western Washington this weekend. Snow levels will fall to 1000 feet on Saturday and then to near sea level or just a couple hundred feet on Sunday morning.  Snow accumulations can be highly localized depending on elevation and how convergence zones decide to form. Locations from Seattle north to the islands and Skagit county would be the most likely places to see accumulating snow.  Locations that get snow could get a few inches while many other locations will just get flurries or left out altogether. The character of the event will be similar to the one that happened on December 29th. Though the exact location of the heavier snows could very well be different.

Monday and Tuesday of next week will be cold and dry.

Starting Wednesday through the end of next week. There is the potential for a widespread heavy snow event somewhere in western Washington. Great uncertainty  exists in a forecast with this much lead time. And it is possible that a heavy snow situation will not happen. Check back late this weekend or by Monday for the latest on this potential high-impact event. If the potential still exists at that time. Then the dry weather on Monday and Tuesday would afford an excellent opportunity to prepare.
