Weekend Forecast: Mountain snow on the way, heaviest over the Cascades
Most of Washington and Oregon's precipitation tonight through early Sunday will stay confined to the mountains.

After Wednesday’s record breaking warmth, a return to seasonal temperatures for early December may have felt quite shocking this morning!
