‘Rollercoaster’ temps mean Sudbury set both a snowfall record and a heat record in May

Just when you thought things couldn’t get any stranger, Greater Sudbury set both a snowfall record and a heat record in the month of May.

Of course, living in Northern Ontario, severe fluctuations in temperature are nothing out of the ordinary. As they say, if you don’t like the weather in Northern Ontario, wait five minutes.

May 27 brought with it sweltering heat, with the temperature reaching a blistering 32.1 C, according to Environment Canada. That beats the record of 30.7 C set back in 1977, said Peter Kimbell, a meteorologist with Environment Canada

Hot air masses settled across much of Ontario that day.

“It was an unusually hot and humid air mass plaguing all of southern Ontario and parts of Northeastern Ontario, up until about the Timmins area,” Kimbell said. “Everyone was sweltering at the same time.” 

Beating a heat record that is 33 years old is one thing, but beating a snowfall record that is more than 90 years old is another.

Remember the snowstorms on May 7 and May 8? Over those two days, 16.4 centimetres fell, breaking the 1929 record of 15.7 centimetres.

The next highest amount of snowfall in May was 11.8 centimetres in 2004.

The average snowfall amount for the month of May is 1.9 centimetres

“It’s kind of crazy to go from snow to 32.1 C in a month,” said Kimbell. 

Things are improving gradually as a cold front sweeps through the area, he said. This weekend will be notably cooler, perhaps a bit “extreme” on the cold side, with temperatures dipping to 10 degrees below the norm for this time of year.

“It may make it a bit unpleasant for people going out to their cottages, but at least it won't rain, or at least not as much as it will be today and tomorrow,” Kimbell said.

Saturday’s high is expected to be 10 C, while Sunday’s high is expected to be 11 C. The normal high for this time of year is 20 C.

Temperatures are expected to bounce back closer to normal next week, though, Kimbell said. 

“There’s no clear signal with the temperatures being above or below normal at this point, but the weather can and does change pretty regularly, and anything beyond 10 days is almost impossible to forecast,” he said.
