It isn't unusual for temperatures to break 30°C in the Sault region during the summer heat. What is notable, though, is for it to last beyond a few days. As we head into this weekend, many locations have already counted five days with daytime highs above 30°C. I searched the weather archives and had to go back to July of 2007 to find that last time there were five consecutive days above 30°C.
As we look into the future, we could still count another five days of temperatures over 30°C - meaning ten or more consecutive days for this heatwave. Now that's totally outside any previous stretch of weather that I could find in weather records for Sault Ste. Marie. The only event I could find worth comparing was July of 1988. The Sault area has six days over 30°C, three of those days were over 36°C; on July 7th of that year we recorded the highest temperature ever in the Sault at 36.8°C,
A northwest breeze may keep daytime highs close to 27°C near Lake Superior on Friday, but elsewhere, the temperature will likely break 30°C again. Skies will be mainly sunny with a few afternoon clouds.
Saturday will be mostly sunny with daytime highs of 31°C and near calm winds.
We might have a few more clouds on Sunday, but there will still be lots of sunshine and temperatures near 33°C.
The relentless heatwave and dry conditions are far from over and will continue well into next week.
