It's less sunny that it would have been today because smoke from the western wildfires has come in overhead.
The National Weather Service confirms: "There is a hazy appearance to the sky this afternoon. This is a result of smoke lofted from wildfires out west being caught in the jet stream and moving overhead at about 20,000 to 25,000 ft."
