Gunny. I thought that the clouds had a bit of a smoky look to them... though I'm at the west end of Fairfax county with winds in the lower-levels of the atmosphere out of the west. So it may be my imagination after all... hopefully... there was an area of smoke rising from about a mile or a few NNW of the Costco in Sterling, VA as I was leaving there around 5:30pm...
61/12 at IAD currently. A 49F dewpoint depression and 14% relative humidity. Great day for outside burning.
