I competed in a triathlon in ‘15 with similar conditions in n Kelowna. The day before was fair weather in the upper 80s. Not a hint of smoke. It was the summer weather that makes the place a tourist trap. Wind shifted to south overnight and a plume from a fire in WA descended upon the Okanagan valley. Not a hint of fog in these photos—all smoke. When we drove over the Connector that afternoon to get back to the coast at 4,000ft elevation, the smoke was still there but about a quarter of what it was. It was a beautiful sunny day up there. I was hoarse for a couple days besides smelling like a campfire.
Both models handled it poorly, just in different ways, so not really. That said, if you live in the central US and don't enjoy the heat, you'd better hope the 18z GFS is way off in the long range.
Had an AQI over 800 earlier, and it's still terrible. The moment I stepped outside, I could feel it in my eyes and lungs. Lake breezes are usually a good thing this time of year, but today they just pulled more smoke into the area, leading to the worst AQI the Chicago metro has ever recorded.
Still managed lower 90s despite the smoke and onshore wind tho.
