I’ve to inform you about this, although a number of the forecasts are loopy excessive.
For a number of forecast cycles, the fashions have advised that later this weekend and subsequent week record-breaking chilly and snow hit the area.
Sure, lowland snow.
Let’s begin with the vaunted European Heart mannequin. The totals for the subsequent week (via Tuesday morning) are proven beneath. A dusting over the lowlands and big quantities (2-4 ft) within the mountains.
The American GFS mannequin is analogous with massive mountain snows, however it additionally had a band of 1/2 toes over the south Sound.
And the U.S. GFS has much more lowland snow via Thursday. Moreover, the totals via mid-November are sheer insanity, with almost 2 toes over Seattle. The American mannequin has issues.
The gathered snow over the subsequent week by the UW mannequin can also be substantial over the mountains and has some lowland snow over western Washington. Of us….we could also be snowboarding by Thanksgiving.

As proven by the climatological snow graph beneath, getting any form of lowland snow in the course of the first two weeks of November is principally unprecedented.
Anyway, thought it is best to know. I’ll hold watch on these forecasts since there’s plenty of uncertainty for such prolonged predictions.
What you possibly can depend on are cooler-than-normal temperatures (together with highs solely getting up into the mid-40s) the subsequent few days within the lowlands and bountiful mountain snow.
The origin? A robust trough of low stress alongside the coast (see upper-level –500 hPa pressure–map for tomorrow morning), with the blue and purple colours displaying a lot decrease than regular heights (or pressures) aloft.
And we’re assured {that a} highly effective atmospheric river will deliver a plume of moisture to the coast on Friday, leading to substantial rain and mountain snow (see the forecast of complete atmospheric water vapor for Friday, beneath)
So don’t be concerned about wildfires, drought, or lack of snowpack—we are actually coming into a interval of massively chilly, moist climate. The yin and yang of the climate is sort of evident.
