Just a brief note. After passage of a Pacific front last night, the freezing level has plummeted to approximately 1500 ft. Snow level is roughly 1000 ft below that. The winds in the lower atmosphere are from the northwest and the lowlands will be mainly rainshadowed from the incoming instability showers over the Pacific. The mountains on the other hand will AGAIN be hammered with snow...with 1-2 ft in many locations. I don't expect much snow action reaching sea level due to the marginal temps and lack of precipitation, with one exception--there could be a weak convergence zone today. In fact, as shown in the radar image, one has already started to form:You can also see the general scattered showers in this image and the rainshadowing outside of the convergence zone over the lowlands.
The snowpack, shown below, is rapidly rebounding. And since local water utilities, like SPU, have gone into water saving mode early, we are actually in pretty decent shape now. Skiing will be excellent this weekend. The strange thing for me is that yesterday I flew in from NY, where temperatures came close to 90F.
