Almost seems like they do because it was distinctly cooler across the whole NW OR and SW WA area. With actual rainfall in May and June unlike this year. As my post stated.
I flew into Denver in October 2020 and there was a ridiculously massive fire burning, don't remember it's name, but I believe at the time it was one of the biggest in Colorado state history. After going through what we went through in September, it was a bit surreal to see the pyrocumulus cloud from the air. On my way back 4-5 days later I stopped again for an overnight layover in Denver and it snowed about 6".
