The famed three H’s of summer – hazy, hot and humid – have suddenly found themselves forced into making room for … smoky.

Weather forecasters are now expecting blow-down from Canada’s ongoing wildfires to revisit our skies all summer long. Adding to the haze are new blazes. Copycat arsonists could be joining natural causes.

For us, any purple haze – had to get that in there for Boomers – could be enough to lower daily high temperatures by a couple daily degrees, providing conditions are right. Blowdown is most likely with calmer air or north winds.

Our regular summer southerly winds from entrenched Bermuda high pressure systems would regularly blow the skies clean.
