When I was outside last evening, I couldn't help but notice the milky appearance to the moon in the sky. This was clearly caused by high altitude smoke, which originated from the large fires up in the Northern Territories.
The high resolution image below from NASA yesterday clearly shows the plume of smoke over the eastern Great Lakes region.
I do believe that these waves of smoke, which have been coming into central and eastern Canada along with the eastern U.S. this summer have had an additional, slight cooling effect on the daytime temperatures in the regions.
I received an email from one of my readers in Alberta describing the situation in Airdrie, which was hit with several severe thunderstorms Thursday which caused large, damaging hail. He stated that the hail accumulated 3-4 inches (8-10 cm) in some spots!
