Most of us are familiar with the polar vortex.

Last winter, the cold outbreak sunk deep into North America and brought frigid conditions to much of the continent.

But the polar vortex can happen in July too and essentially during mid-summer, it means the jet stream is taking an unusually deep trek south.

For Ontario, it has meant below seasonal temperatures this July.

As a matter of fact, St. John’s has had more days above 25 C this month than Toronto which is fairly significant given the Ontario capital’s typical hot and humid weather during July.

Fortunately, New Brunswick like Newfoundland has been on the other side of the jet stream this month with warm, sunny days and above seasonal temperatures.
