Pacific northwest dry and burning as rest of West has a cool and moist summer respite-
We planned to go to B.C. and Alaska this summer. Glad we didn’t. Instead we stayed in Pocatello, Idaho where a very wet late spring and cooler than normal summer has greatly reduced normal fires and given clean skies.
On the other hand much of B.C. and Alaska have been very dry. Massive forest fires burn out of control, and Oregon and Washington too have recently suffered from extreme heat. Smoke from the fires has resulted in dense air pollution to the north, while most of Idaho, Montana, Utah, Colorado and Wyoming have escaped the smoke. The winds are now, however, blowing the smoke down into Montana, Northern Idaho, and across the Dakotas and Great Lakes.
Fires have broken out in Northern California, Oregon, and Washington, setting the stage for smoky skies further to the south. Some relatively small forest fires are now burning in Idaho and Montana (just updated), although this season will probably not see many large forest fires due to the still relatively wet wood.

Fires burning wild across Interior Alaska. Smoke: Two expand beyond 800,000 acres; 30 cabins threatened. By Kyle Hopkins. Well 30 threatened cabins doesn’t sound like a major event, but 800,000 acres in two fires does.
I should add that the desert southwest has suffered from extreme heat (more extreme than the usual during the summer)
