Here, in Seattle, the smoke was amazingly thick on Wednesday morning, just exceeding the extreme event that occurred in September 2020 and on par with the smog period in the summer of 2018 (see particulate matter levels at the National Park Service). Lake Forest member for the past 5 years).
Intense smoke associated with a dying fire (Bolt Creek) in the Skykomish Valley.
How is this possible?
The explanation is found in my podcast (see below). “Perfect storm” of meteorological conditions.
And speaking of perfection, consider the weather conditions in the Northwest this weekend.
EVERY other high-pressure peak will develop on the West Coast this weekend (see upper deck map, 500 hPa – about 18,000 ft as of late Sunday below). And you know what that means….warmth and sun.
But this time of year we can’t get really hot…so high temperatures will only be reached in the upper 70s in the west. Almost perfect. Although it won’t last long… cooler temperatures midweek, light rain is forecast. My podcast goes into detail.
