Rich, Lynne, and others,

As I just briefly logged on, for another reason, and spied your
question, here is an EFI CDF plot for Seattle. From which you may conclude:

Wet or very wet or dry or snowy or very snowy or slushy. And maybe windy
and maybe not. And I am sure there is scope for plenty of local detail
to be added to this! :)

For reference EPS is ~60km resolution at this range, so the mountains
will not be very well handled.

Similar plots for places further S (not attached) denote higher
confidence of very wet, as, synoptically, one would expect.

The pattern is ideal for the NCEP models as the GEFS is showing a huge closed 100 mm  with some smaller 125 and 150 mm contours in the west for total QPF.
 High plume of moisture, westerly winds, big mountains and models know big QPF.
 Should be iteresting.
 Anyone have access to the EFI. This must be a top 80 or 90 percentile rainfall event in the model atmosphere. We need to know.

   To add to the discussion....attached a powerpoint slide I made
   showing the NOAA/NESDIS Blended TPW data and Percent of Normal
   products for 23 UTC January 14 showing the moisture players that are
   certainly getting organized this evening across the Pacific Ocean.
    Interesting moisture plume/atmospheric river extending from the
   Philippines to front just wast of the dateline and extending to near
   high moisture north of Hawaii.  If this works out, it will be more
   than a pineapple connection...it could be the Southeast
   Asia/Philippines mango-pineapple connection.

       Or one could look at Squaw Valley web cams to get a closer look:

           The incoming jet may be a little surprised to see the Sierra
           Nevada (snow covered mountains) looking different.
