Overcast, sprinkles, 70 dewpoint. Disgusting. Fall can't come soon enough.
Don't know why, but muggy air always feels dirty to me, no matter what the air quality - and the lower the dewpoint, the cleaner and fresher it feels, even with wildfire smoke!!
(I think it might date back to when I was a kid at summer day camp. I had to join in with strenuous athletic activities in the worst of the Northern Virginia summer, and my mother would always dress me too warm, in dark colors, so of course I got prickly heat and was pouring with sweat; to this day I despise the smell of wet grass for the same reason. And my house didn't have air conditioning back then either!)
