Thursday AM update: The snow is already falling in parts of southwest Washington, and KOMONews.com meteorologist Scott Sistek says it's just a taste of what we might get tomorrow (Friday).

Scott talks about some of the variables that might affect the snow totals: how the east winds could "eat" some of the snow before it falls, and how those juicy tropical systems on the way may have a lot of moisture in them to add to the snow totals.

We talk about the timing of the Thursday storm, the Friday storm, and get Scott's latest thinking about a storm headed our way Sunday night.
