Greater Sudbury, along with most of central and southern Ontario and Quebec, will be seeing hot and humid temperatures until this weekend.
A warm air mass has settled over both provinces, bringing temperatures in the upper 20s and low 30s. The humidity will bump those numbers into the 30s and 40s.
In Greater Sudbury, temperatures are expected to reach highs between 27-29 degrees Celsius throughout the week, with humidity-affected temperatures reaching mid-thirties.
According to Environment Canada, the high today, July 6, is expected to hit 29 degrees Celsius, but feel more like 36 degrees Celsius because of the humidity.
Peter Kimbell, a warning preparedness meteorologist with Environment Canada, said the hot weather isn't something people are used to.
"We haven't had hot summers for a few years now," he said. "Last year in 2009, there were a total two days with temperatures reaching or exceeding 30 degrees. In 2008, (there were) zero. In 2007, five. And in 2006, nine."
While the humidity is pushing the temperatures into the mid-30s, Kimbell said it's the temperature without the humidex that is tracked.
"This year we've only had two (days above 30 degrees Celsius) so far, those very hot days at the end of May," he said.
"This week is going to be very hot unquestionably, but it's not going to break records in the Sudbury area for heat. It's just going to be very muggy."
Kimbell said another weather system should begin to move in to the area on Friday, bringing cooler temperatures and lower humidity.
Smog warnings have been issued for southern Ontario up to Parry Sound, but Greater Sudbury is not included. Areas of Quebec have had weather warnings issued because of the heat and humidity as well.
