Snowy February, Dry March
Seattle’s February snow pack is long gone, but there is still plenty of snow to be found in the mountains. They got a help from the storm track last month, which was well positioned to blanket Washington and northeastern Oregon with precipitation. To get an idea of the shape of the storm track I’m showing
One of the biggest snowstorms in decades takes aim at Seattle
This is the real deal, a significant 1-2 punch snowstorm is headed for the Seattle metro area beginning Thursday and continuing into Saturday night. Significant snowstorms are extremely rare in Seattle because it is nearly impossible for a storm system to combine cold, arctic air from east of the Cascades with warm, moist maritime air
How much is it going to snow in the PNW lowlands this week?
Time to stock up on bananas and hunker down, the snowiest period since February 2019 is headed for the Pacific Northwest. While there is still some uncertainty about specifics, there is high confidence that the western WA lowlands, particularly the Seattle-Tacoma-Olympia corridor, will experience a period of snowfall at the end of the week. In
Arctic air heads for the Pacific Northwest
The Pacific Northwest has seen little in the way of true winter weather so far this year. With the days getting longer and spring rapidly approaching, time is running out to get some real cold into our region. One month ago I wrote about the possibility that the polar vortex would be paying a visit
5 reasons why a significant Puget Sound windstorm occurred with almost no warning
After the rainiest start to a year on record, a moderate windstorm blasted through most of Washington State with surprisingly little warning. Widespread wind gusts in the 45-55 mph range were recorded in central Puget Sound around midnight – 1 AM on Wednesday January 13 with a max gust of 61 mph in Federal Way.
Will sudden stratospheric warming (SSW) lead to an arctic cold blast in late January?
The calendar shows that it is now January 2021 but winter weather has yet to make much of an appearance in the continental United States. Temperatures over the past 30 days have run above normal over the majority of the US and Canada. Not surprisingly, snow depth is below normal over a large portion of
Assessing the potential for lowland snow in the Seattle area on Monday evening
Western Washington snow fans haven’t had much to cheer for yet this year, but weather models have hinted at at least a slight potential for snowflake or two on Monday Dec 21. On Saturday afternoon, NWS Seattle issued the following statement about the potential. The NWS graphic suggests that snow will generally be confined to
Why was Saturday’s convergence zone stronger than expected?
After a weak frontal passage overnight Friday, the general consensus was that the Seattle area would experience clearing skies by Saturday afternoon with perhaps an isolated shower or two. Unfortunately the weather had other ideas. A little after 8:30 AM, the main frontal band was already well off to the southeast and skies were clearing…except
Stormy, wet conditions likely to persist into December (or longer) as La Niña strengthens
November is climatologically the wettest month of the year in the PNW and that has certainly been the case so far this month. Tuesday’s powerful cyclone, pictured below, capped off a impressive week with convective squall lines in the Seattle area, strong winds, high surf/beach erosion on the Pacific coast, and an early snowpack buildup
Winter begins in the Cascades
It was a stormy weekend for the Pacific Northwest. Early last week Washington weather enthusiasts were excited about a possible windstorm that wound up striking further south (50+ mph gusts in Newport, Or!), but I was looking forward to something different – the first big snowfall of the season for the Washington Cascades. Active weather
