SEATTLE, WA - There's a lot of uncertainty about the possible snow in Puget Sound on Sunday night and into Monday. The National Weather Service's guess: anywhere between 0 and 4 inches for the Seattle-Tacoma area.

The NWS is using the word "spotty" to describe how the storm will hit the region. That means snow totals could be highly variable. The storm will begin Sunday morning with rain showers. Wind will pick up this afternoon in Whatcom County.

The snow will start very late Sunday night and continue into Monday morning. On Saturday, the NWS's "best guess" for snow between Everett and Tacoma was 0 to 1 inch. The "worst case" is 1 to 4 inches.
