We're dealing with some of this in my neck of the woods as well.
On top of two weeks without any rain (though the cool weather has kept the water table from plummeting, so we're OK for now, though the grass is in full late-August mode). Basically the whole area smells like barbecue, which isn't horrible. We had some of the smoke from the western Canada wildfires in late May, but those were much higher in the atmosphere and didn't smell of anything. This was all low-level smoke.
To bring the weather side into this discussion, what's going on is that a low-pressure system is parked right to the southeast of these wildfires, and all that smoke is getting sucked into that circulation, which pours down over the eastern United States.
