Some of the thickest upper level smoke #WesternWildfires is over greater Boston this morning. You really get a sense for how massive the fires have to be for this amount of smoke to make it all the way across the country and be basically dimming the sun this morning.

I won't even ask, who is ready for a nice weekend? If you include civil Twilight you'll have over 30 hours of light to get outside this weekend. Wow!!
