The other day, I saw a news item warning of excessive heat—telling people to stay hydrated (isn't it interesting we say that now, instead of "drink lots of water") and talking about the symptoms of heat exhaustion and heat stroke. Yuck, thought I.
So this morning, knowing we were in for hot weather, I was expecting glaring sunshine. But when I drove my car to work, my first thought on pulling out of our cul-de-sac and driving east was, "What a weird sky." It was overcast, but not in a way I had ever seen. I thought it must portend some bizarre weather. It was hazy, just hanging at a certain height, obscuring the hills.
On my lunch break, I saw on the internet that smoke from wildfires in British Columbia is blowing into western Washington. That's why the sky looked different from anything I'd ever seen in Washington before, because it wasn't cloud cover, it was smoke.
I downloaded this satellite image, so I could mark about where my town is, but the original is here, and the caption for the photo says, "Photo from NASA MODIS satellite taken on Aug. 1, 2017 showing wildfire smoke spreading south into Western Washington (Photo: NASA/MODIS)":
