The Olympic rain shadow protected us from rain last night and it may protect us from the possible lowland snow event.  However, it may not protect us from the wind and rain tonight....  A Wind Advisory and a Small Craft Advisory have just been posted.... This recent Tweet from Scott Sistek....

After reading a variety of forecasts, I decided to distill it down to 5 simple bullet points.  This is a very broad brush look, but it gives us a general idea of what is forecast for our future…. 

  1. Rain will return tonight and into Friday along with possible wind advisories.
  2. A brief lull and then heavy rain and stronger wind Friday night into Saturday.  Again, possible wind advisories.
  3. Heavy snow in the mountains over the next few days.
  4. Cold, wet weather moves in late Saturday into Sunday…  Possible lowland snow…. Followed by an Arctic outflow…. REALLY cold weather and north winds.  This will last through at least Wednesday.  We could see some record low temps over this period.
  5. Possibility of some lowland snow on Wednesday. 

This will get your attention….  A quote from Cliff Mass’s blog:

“WOW.   East of the Cascades many locations will get below 0F, some locations will be way below.  Twenties near the water and teens elsewhere in western WA”.

Here is the link to his blog:

From Cliff's blog, the images below show the WRF-GFS model forecasts for temperature and wind on Monday and Tuesday early morning...
