Seems to me like the GFS is starting to lock onto a solution for the Monday-Wednesday period... It's definitely not a region wide outbreak. There is going to be a battlezone between rain and snow, and it will probably be somewhere between the northern 1/4 of WA and Southern BC. Could be January 2011 all over again, or January 2012... Or December 1996. We're talking about a couple hundred miles making the difference between a once in a 25 year event or an average snow to rain event.
