Current predictions, which are usually pretty close,---snow in the Pacific Northwest --second week in November !!.. Have lived in this area for 10 years and these predictions are usually pretty close..

One thing to keep in mind – any place you might go during the winter season it is advised by Highway Patrol to carry chains. however, with rare exception, all rental companies prohibit using chains as could damage the vehicle. As a" local" person I have all weather tires and four-wheel-drive--

I wish you good luck in your endeavor – – Mt. Hood area is beautiful at any time of the year..
