It might not be all that bad (as in not post-Christmas '96 bad)...

Now for the interesting part...the possibility of heavy snow as we
transition to warm air on Tuesday and Tuesday night. 00z ETA model and GFS
guidance continues previous thoughts of moving precipitation onto the coast
late Monday night and into the interior early Tuesday morning. All snow to
start off. Offshore gradients and an initially deep cold air mass
keep 850-1000 mb thicknesses below 1305 meters with offshore
gradients in the Seattle Everett area until 7-10 PM Tuesday evening.
This is later than previously thought. Latest model precipitation amounts
vary with mm5-ETA model initialization and mesoeta indicating 5-10 inches
around Shelton...and 1-3 inches in the greater Seattle area. The GFS
MOS and GFS show a generalized 6-8 inches. The GFS initialized mm5
shows 7-12 inches around Shelton and 3-5 inches around Seattle.
