Portland Snow!
I try and tell people that the only way to get out of these deep freezes that you are in is to have a system move on through to scour out the cold air. This is the typical snow storm. High pressure to the east with very cold air, low pressure from the south with warmer wet conditions. South of salem will be nice and rainy quickly. However that good ol' gorge acts to keep the rest chilly. Skyline, you will warm up before lincoln will, its just how these work. It is called an inversion, cold wind will pump out of the gorge and keep places liek PDX and troudale cold whereas West hills will pick up a south wind and warm up. Nevertheless, all of portland will see snow tonight and tomorrow, followed by sleet and possible freezing rain. I say in total about 3-4 inches before rain comes later saturday night. Warmer system Monday should melt most of the snow! :( REMEMBER, West and High elevation=warm and East and low elevation=cold.
