Snow and Ice Pellets over NW Washington

It is snowing in Eastsound on Orcas now and ice pellets are raining on Bellingham. On the other hand, for the rest of us there is moderate rain and rapidly warming temps.
Check out the latest radar...you haven't seen wet like that in a while.

And here are the latest surface obs. The approaching low is sucking air out of the Fraser River Gap with cool NE flow moving into Bellingham and the San Juans. Won't last forever--eventually they will turn to rain too.Why? Because a warm front is approach (see graphic) and when it passes through warm, strong sw flow will inundate the region. You will feel like you have gone to Hawaii...well, sort of.

This figures provides temps in the lower atmosphere..yellow is warm and blue and white are cold. Also pressures and winds.

Snowing in the mountains (see cam at Snoqualmie)...and they are going to get hammered..which is really good for all you skiers.


PS: A reminder--I will be giving a talk.."The Secrets of Snow" at 7 pm at 3rd Place books in Lake Forest Park on Thursday, Dec 17th.
