Puget Sound region could be blanketed under 18-24 inches (45 to 60 cm) of snow by the the middle of next week, says expert.
“You might stock up on food before noon on Friday. “I certainly am.”
6 Feb 2019 – “There is going to be a major snow event over much of the Pacific Northwest starting late Friday and continuing into the weekend,” warns Cliff Mass, a professor of Atmospheric Sciences at the University of Washington.
Low pressure centered at the southwest corner of the state will pull cold air down from Canada while pushing moist air up into the atmosphere, creating what Mass calls a “perfect snowstorm situation.”
Once the storm begins, says Mass, snowfall will be “extraordinary”, with up to 8 inches over Puget Sound within 24 hours.
But that’s just a lead-up to the main event.
A second storm starting Monday could leave the Puget Sound region under an 18- to 24-inch blanket of snow, says Mass. “Unbelievable.” A “snow apocalypse.”
“What is forecast to occur late Friday and this weekend is absolutely classic,” says Mass. We’re looking at “one of the greatest snow events in decades.”
Authorities “need to get prepared for perhaps the snowiest period since the large snowfall of December 1996,””when Seattle received 21 inches,” says Mass. “And yes, you might stock up on food before noon on Friday. I certainly am.”
How confident is Mass in the forecast?
When it comes to the second storm, says Mass “roughly 2/3rds of the forecasts are going for a large event …ending up with around twenty inches by the the middle of next week.” (The reddish colors on the above image indicate around a foot [30 cm] of snow.)
Mass ends on an ever so slightly upbeat note, admitting that “there is a lot of uncertainty for the second event.”

Mass has published more than 100 articles in peer-reviewed scientific venues, and served on the board of over a dozen regional and national meteorological committees, conferences, and scientific journals
He is also a strong believer in human-caused global warming and “has been critical of the Paris Climate accord for not going far enough.”
