Southern Ont., Quebec looking at most severe weather day of the season Thursday – The Weather Network

There is the potential for a few showers or thunderstorms on Thursday morning, but there should be sufficient clearing in the afternoon to recharge the atmosphere ahead of the passage of the cold front.

By the late afternoon, and as the cold front nears, the more intense thunderstorms are likely to continue into the evening hours.

Torrential rain, strong wind gusts, large hail, and even a tornado or two are strong possibilities for Thursday. Be sure to be weather-aware as damage is possible given the severity of this system.

The dreary, stormy weather will stick around through the overnight Thursday, giving Friday a less-than-ideal start. Things will turn around in a hurry however, with the region finally looking to pull off a dry weekend — the first in the GTA since early April!

Saturday will be a gorgeous day with abundant sunshine, light wind and comfortable temperatures during the afternoon. A mix of sun and clouds is expected for Sunday.

By next week, conditions will become hot and very humid for most of the week, with high temperatures soaring into the low to mid 30s for a few days, and a 40+ humidex. However, with the very muggy conditions will come a risk for thunderstorms, once again.
