I checked the webcams several times today and it was variable. Very yellowish-brown in the morning in all but TM, then very hazy and yellow midday, then almost clear by about 6pm. TM itself was fine in the morning, then got worse up until mid afternoon, then cleared, but Grand Mountain in the distance had a sickly yellow haze in front of it all day. There might have been some low clouds, but the color was what I was going off of. Maybe some low clouds, but the smoke is a huge factor. I did wonder about the High Sierra cam, but it's right up there next to the Empire Fire, and the Badger Pass cam showed some really gross air just hanging in the valleys.
Here's this again, updated for today.
