Most areas in Metro Vancouver currently have 2-15cm(1-6in) on the ground after a significant snowfall today.

We will likely have a White Christmas as the long range forecast looks fairly dry and chilly.

Euro00z 5000' temp anomaly Christmas evening. Core moves into Northeast next day. Euro slower with that front. GFS says Christmas is much colder for here and Vermont because its bit faster with that front
here's what the GFS says for the actual 850 hPa temperatures rather than anomalies. A very cold airmass; -32°C over the Upper Midwest. I like that tropicaltidbits masks out areas too high in elevation to have an 850 hPa; often those numbers make little sense when they're interpolated from above. Neat way to show where the high elevation areas of the West are, too.



Euro. Finally checking out that weather.us site Ryan Maue is a part of



slightly different timing, same pattern. 850 hPa only reach -28°C. And here's surface temperatures over Canada and northern US. Notice the contrast east vs west of the Rockies and the tongue of cold entering Wisconsin

watch this for airmass temperatures

Just switched over to snow in Bellingham, was raining there before. Big contrast right now: Seattle is 43°F and Bellingham 34°F. Seattle is forecast to get a few flakes overnight; looks like you're getting a nice stretch of sun for the next few days after that; though rather chilly.
