We had weird weather here today, the sky a dirty yellowish white, the buildings on the horizon a soupy grey and and the sun a fuzzy orange. The light reminded me of Shanghai so I checked the AQI index and saw we were in unhealthy territory. By evening it reached 167.
But where could all that fine particulate matter be coming from? Eventually we learned the reason. We'd read that the Oregon Bootleg fire was generating its own weather, smoke in a satellite view streaming eastward... should have remembered it could reach us!
