Video from July 30 shows the wildfires in Canada burning through the night in Saskatchewan before daylight when smoke can be seen in the atmosphere.

So while millions are finally experiencing cool, less humid air, they unfortunately cannot take advantage of it, due to the presence of the thick smoke.
