Weather forecast Cascades - Early December

Issued 11-30-2011.
Starting on 12-1-2011 and continuing through 12-9-2011 forecast models bring a ridge of high pressure at the surface and aloft. This pattern will bring below normal temperatures and below normal mountain snowfall. Basically weather systems and the associate snow will be steered to the north and south of the Washington Cascades. We might get a few weak weather systems that try to move into bring some light snowfall but light snowfall if any is the main message.
The map below is the 500 mb map (about 18,000 feet)and this indicates a ridge of high pressure off our coast and this pattern usually brings mostly dry conditions.
