Here's a screen grab of video from the Mariners-Athletics baseball game.I thought I could taste the smoke today. It's bad.
And Eastern Washington is supposed to be worse then western Washington.
An interesting article in the Seattle Times about how the smoke is throwing off the atmospheric behavior models used by meteorologists - resulting in heavier smoke levels than predicted.
In a nutshell, one of the primary factors that causes mixing of air is the heating of air that occurs at the ground surface due to solar radiation. Like a cloud cover, the smoke cuts down on the amount of solar radiation reaching the ground surface. But unlike a cloud cover, the smoke does trap heat radiated by the ground - that is the element that hasn't been captured in the models.
So with less radiation reaching the ground surface, and no trapping of the heating that does occur, the ground level temps are cooler than predicted. And since cold air is heavier than warm air, the smoke is trapped at the ground surface.
