The operative phrase for the following few days might be chilly, notably east of the Cascade crest.
However there are two uncomfortable side effects of chilly: very excessive floor/sea stage strain and the potential for lowland snow.
Within the second phase of the podcast, I be aware the intense excessive strain shifting down the japanese aspect of the Rockies, japanese WA we are going to get a “piece” of the high-pressure motion (see the ocean stage strain forecast for subsequent Thursday proven under). 1054 hPa!
However as famous within the podcast, the spectacular excessive strain doesn’t beat the U.S. document (1064 hPa in 1983).
My podcast begins with the forecast. The large motion this weekend might be late Saturday and Sunday as a chilly entrance strikes southward via Washington State. There may be be each rain and snow showers, with the previous dominating close to sea stage.
The 24-h snowfall complete ending 4 PM Sunday is proven under. Essentially the most lowland snow might be over Northwest WA, the place cool air jetting out of the Fraser River Valley is critical.
There may be one other probability for snow on Tuesday–more on that within the podcast.
