Pattern through Christmas

Tomer’s Take: The place to be through Christmas is the PNW, BC, Banff, ID, MT, WY, UT, CO where an Arctic front will direct the pattern. In the Northeast, the Western Arctic front develops into a large low pressure on/around 12/23. Unfortunately, it looks too warm with snow to rain then back to snow.

My forecast video 12/18:

    Hey Chris how about add Hunter mountain to your list. New York State has the most ski areas out of any state, Hunter could be the NY contingent 😁
