Doing my best Rod Serling, imitation... " Imagine if you will. It's early January 2008 Portland and the Willamette Valley is blanketed in snow. Television stations are going with wall to wall 24/7 coverage of " The White Wall 2008."
No - it's not the Twilight Zone, but it's close. If this same weather pattern occurs a couple of months from now, it would bring snow onto the valley floor. Not just a skiff or a trace but several inches. For the first time this season snow advisories are posted for both the Oregon & Washington Cascades.

The snow level will hover around 3500ft through Late Thursday. At that elevation all of the Cascade mountain passes will get snow. The highest peaks in the coast range will even get a dusting. In Oregons mountains up to a half foot is possible. Washington state will get up to 10".

The Jet Stream is dragging cold air all the way down from the Aleutian Islands and has pushed into Northern California. Left over moisture from yesterday's storm gives what local meteorologists call "a short over water trajectory." In english - it means showers have a short distance to travel over the water before reaching land. The shorter the distance over water the less chance of warming. The perfect set up for valley snow in January or February.

Thankfully it is only October and were not in the Twilight Zone of wall to wall coverage. Not yet anyway... But Imagine If...
