“The humidex Saturday is in the low 30s, we’ll be talking mid-to-upper 30s as early as Sunday and that’s when the real heat starts to build in from the mid-west,” said Global News Chief Meteorologist Anthony Farnell.
“On Sunday, winds really pick up from the southwest. We are expecting very hot conditions all across the GTA and really, all of southern Ontario,” Farnell said.
“We could be breaking records as early as next week.”
Areas affected by the heat warning include:
- Peterborough-Kawartha Lakes
- Prescott and Russell
- Smith Falls-Lanark-Sharbot Lake
- Windsor-Essex-Chatham Kent
The warm temperatures are expected to persist through the beginning of the work week, with highs of 33 C forecast for both Monday and Tuesday.
“It is a heat wave and it lasts through Tuesday,” Farnell said.
“We get what we call a backdoor front, it actually comes in from the north east – that will bring the temperature down on Wednesday … [it will warm] back up 26 on Thursday (and) 28 on Friday.”
The warm weather will be welcomed by some after the high levels of rain Toronto has experienced over the past recent months.
