A significant snowstorm will continue to bury portions of the higher terrain of Washington State under heavy snow as the first full weekend of the Autumn of 2020 arrives. By the time the weekend wraps up, Mount Baker could see more than 10 feet of fresh snowfall.

Mount Baker, also known as Kulshan, stands at 10,781 feet tall in the North Cascades of Washington. Mount Baker is the second-most thermally active crater in the Cascade Range after Mount Saint Helens and is considered an active, glacier-covered andesitic stratovolcano within the Cascade Volcanic Arc.

A Puget Sound Convergence Zone  (PSCZ) has developed over portions of western Washington, setting the stage for significant precipitation rates today.  While precipitation will taper a bit into Saturday as a weak front moves through, a more significant round of precipitation could set-up on Saturday night and Sunday morning for a PSCZ event.




With this type of set-up and an abundant stream of moisture coming off of the Pacific Ocean, Mount Washington’s height will help create the perfect atmospheric snow machine. While rain rates at lower elevations could be as high as 1/2″ per hour, heavy snow could fall with many inches per hour over a prolonged period of time

In terms of snow, totals today are forecast to be around 2-3 feet, with another 1 foot possible tonight, and another foot possible tomorrow and tomorrow night …on top of more than 4 feet that already fell from this system since Wednesday.
