Ugh. I had just made up my mind to go late, but my wife pointed out that my twin daughters have their first basketball tournament that weekend. So back to going on the 11th. 
Anyway, great info. I'm hoping for snow. One of my hunting bucket list items is hunting deer in the snow. Looks like I may get that wish. Hoping the rain and snow mix forecasted will be mostly snow - we are a bit higher in elevation than Colville.
Gotta be a little careful what you wish for. I've hunted in the snow many times over the years and it can certainly be a two sided thing. Yes, there are a lot of advantages-visibility, ability to determine fresh tracks, nice clean snow to wash your bloody hands off in as examples. BUT, it is also takes a lot more preparation. Obviously accessability to back roads is more difficult, deer movement can be hard to peg unless you know the area very well, trying to sneak thru crusted snow is near impossible, throwing up your gun to find your scope full of snow is very frustrating, slipping and sliding down snow covered steep hills is not fun-just to name a few. I've found deer really don't move during a hard snow storm, but neither does your vehicle if you're out hunting while it drops a foot or so around it. It's kinda fun at times to hunt in snow, but I can also relate a few times where it was not fun at all. Key is to make sure you're prepared, think thru everything bad it can cause and prepare accordingly.
