Long post, but I will share what I have bookmarked.
https://a.atmos.wash...isc_report.html AFD discussions for all four of those areas in one convenient sites
Local weather blogs:
https://cliffmass.blogspot.com/ UW's Dr. Cliff Mass, blogs about PNW weather and climate, particularly Western Washington
https://fox12weather.wordpress.com/ Mark Nelsen from Portland, a must bookmark for SW Washington and for Portland people
https://www.tropical...019021412&fh=6 GFS, you can change it to 850's, change it to the PNW, etc
https://www.tropical...19021412&fh=6c Euro, same thing
You can also go to the mesoscale models and get the NAM.
https://www.pivotalw....com/model.php Pivotal Weather has the same models, but one difference is the FV3 (for now) allows you to zoom in on the PNW
https://weather.us/m...el-charts/euro For those that do not subscribe to a service, this is a free site that can give you snowfall maps, but be aware it gives you the total precip that falls as snow, so one inch means not one inch of snow, but one inch of precip that falls as snow. Make sure you use the most current map, and it allows you to zoom in on your location. It also lets you see way more parameters than the Tidbits or the Pivotal sites do.
https://a.atmos.wash...edgfsinit.html UW MRF map.
https://a.atmos.wash...les/plumes.html WRF ensembles plume, select your location and the parameter.
https://www.cpc.ncep...4day/500mb.php CPC 8-14 day maps, has links to surface temp and precip maps and discussion.
https://www.cpc.ncep...10day/500mb.php CPC 6-10 day maps.
https://atmos.uw.edu...orthwest-radar/ There are many, but I use this one, it allows you to go from 1 to 8 hours, and to zoom in, and to speed up or slow down the frames per second.

Twitter for bigger weather picture, El Nino, etc.
https://twitter.com/RyanMaue Very interesting, one of the founders of weather.us and full of great weather stats
https://twitter.com/MJVentrice Dr. Ventrice is also very interesting, has a lot of tweets about long ranger weather trends.
https://twitter.com/...BigJoeBastardi I know a lot of people don't like Bastardi because he has an East Coast bias (true), and he does offer a lot of political opinion (true) that some people won't like, but he does know his stuff, especially weather history
