My thoughts are unchanged from earlier. Marginal conditions combined with shadowing for tomorrow in and around the Seattle metro area below 500’ leading to a mix of rain and snow. Precipitation will be scattered in nature. Better chances for accumulating snow Sunday morning when the low moves through SW WA. Favorable temps in Whatcom and Skagit counties with accumulating snow tomorrow especially areas east of I-5.

Can i get one for the Kitsap pen? Mets always act like we don't exist. Come on, now.

NWS Spokane afternoon disco still seems fairly confident on cold blast

 

The well advertised Arctic air mass will begin to seep in from the north  
  on Sunday which will lead to increasing northerly winds down the  
  Okanogan Valley...across the Waterville Plateau...and into the  
  Western Basin. North winds have been increased further for  
  locations like Oroville, Omak, Lake Omak, Bridgeport, Coulee City, 
  Ephrata, and Moses Lake. If these areas are able to pick up a few 
  inches of snow before the winds...drifting and blowing snow could 
  be an issue. This carries low confidence. The bigger concern will 
  be biting wind chills. 
   
  The Arctic air mass will become well entrenched into Eastern WA and North  
  Idaho Monday through Wednesday bringing the potential for some of 
  the coldest temperatures in the last decade. There is no doubt  
  that it will be bone chilling cold. If you are one that likes to  
  dissect the finer details and forecast numbers, please note that  
  these will still change over time and most of the forecast is  
  aligned with the National Blend of Models. Forecast models are  
  indicating 850mb temperatures to dip near -18C around Spokane  
  which is around 15C cold than normal at this level of the  
  atmosphere. In case you were interested, the record for Spokane is 
  -27.6C measured on a late afternoon December 29th balloon (not  
  sure on the year). Needless to say, temperatures at this level  
  will likely translate to temperatures 15-30 degrees cooler than  
  what we considered normal for this time of year at the surface.  
  High temperatures will stand a good shot of only warming into the  
  single digits to teens by Wednesday with overnight lows anywhere  
  from 5 to -20F. Cloud cover is usually the biggest factor that  
  complicates forecasts in these air masses and models do indicate  
  the potential for scattered to broken clouds across southeastern  
  WA and the lower Idaho Panhandle during this Arctic event. As  
  such, the NBM readings have come up a degree or two, especially  
  for lows. Areas further west and north of these clouds will carry  
  a much greater probability of temperatures below zero. Many of  
  those sheltered mountain valleys including locations like Lake  
  Wenatchee, Winthrop, and Republic could be experiencing  
  temperatures near or colder than -15F. Scattered light snow  
  showers will remain possible across the region Sunday into Monday. 
  As the drier, continental air mass bleeds in, look for the water  
  content in the snow to decrease rapidly, becoming fluffier with a  
  high snow to liquid ratio (meaning it will take much less QPF to  
  get the same amount of snow). 
   
  The cold temperatures will continue into the end of the week.  Some  
  moderation is expected but the rate at which this occurs carries  
  low confidence and current thinking is a return to teens and  
  twenties is the most likely scenario at this time. Models continue 
  to hint at our next chance for snow arriving on the Thursday- 
  Friday time-frame as an upper-level trough drops in from the  
  Northwest. Confidence is high that we will not have to worry about 
  snow levels for this event and as it stands right now...this will 
  be a light snow event with amounts generally in the 1-3" range  
  but stay tuned for updates. /sb

I guess I should break out my snow plow! 35 miles east of I-5 paying off!

BLI down to 32/28 with a big batch of moisture approaching from the South. Looks like the games are about to begin in Bellingham at least the SE side of town as it may not hold together further North.

Similar forecast to the Seattle metro for those below 500’ or so with marginal conditions. Accumulating snow tomorrow for those above 500’ 1-3 in.

GFS still hilariously aggressive with the Arctic front. Pushes it through the central Sound by 10pm Christmas day. Onshore flow and heavy precip plummets temps to freezing ambiently by 4pm with snow falling over Seattle. An interesting, but ultimately unlikely (and unsupported) possibility. Afternoon temperatures near 20 on Boxing day. This will get cut back in all likelihood.
