As July draws to a close, Ontario and Quebec could see another round of severe thunderstorms to start the work week.
The main threat will be seen across central and eastern Ontario with some localized thunderstorms prevalent in southern Ontario as well. Towards the end of the week, Ontario will see some sticky, sweltering temperatures sweep across the region.
Areas: Ontario and Quebec
Timing: Afternoon and evening
Weather: Thunderstorms will develop this afternoon and evening in Ontario and Quebec with the greatest chance for severe thunderstorms in central and eastern Ontario as well as western Quebec. Strong wind gusts, large hail and torrential rainfall are possible with localized thunderstorm activity.
Non-severe thunderstorms will pop up in southern Ontario including around the GTA and the southwest. Some storms may become stronger but this is less likely than those areas where the severe risk is present.
Warmest temperatures of the summer?
The strong heat dome situated over central U.S. tilts across the Great Lakes Basin Wednesday and Thursday. Many regions will experience a few consecutive days above 30°C.
The maximum temperatures of this heat event will likely push towards the mid-30s for a couple of weather stations in southern Ontario. Most areas will not see the warmest temperatures of the year so far, however, some areas in southwestern Ontario like Windsor are forecast to reach 34°C on Friday.
Those without access to air conditioning will get little reprieve from the heat as the overnight temperatures will stay elevated in the low 20s throughout the overnight hours.
Keep an eye out for symptoms of heat exhaustion and heat stroke in those most susceptible.
