Muggy air building back in across parts of Ontario and Quebec will bring the threat for severe weather to both provinces on Thursday.

A cold front moving through Ontario on Thursday will trigger a risk for thunderstorms, with the likelihood for some to become severe.

In fact, Thursday has the potential to be the most severe weather day of the season so far for southern Ontario and western Quebec, so it will be important to stay on top of the weather watches and warnings in your area, as conditions can change quickly when severe weather hits.

WATCH: Severe storms hammer Ontario on Thursday

Thursday: Severe weather to bubble up across the province

A strong cold front pushing eastward through the lower Great Lakes region this week will clash with the warm, humid air in place, triggering widespread rain and embedded thunderstorms in its path.

Northern Ontario was the first area of the province to see the active weather as storms rolled through the region Wednesday night. The predominant risk comes to southern and eastern Ontario, and western Quebec later Thursday.

Temperatures in the mid- to high-20s will feel like the mid-30s with the humidity on Thursday. Folks in Toronto will be seeing an already scorching daytime high in the upper 20s, but the humidex will make it feel well into the 30s. This will create enough energy in the atmosphere for strong storms to develop upon the cold front's arrival later in the day.

There should be sufficient clearing in the afternoon to recharge the atmosphere ahead of the passage of the cold front. Most of southern Ontario should stay rain free the majority of the day

While there is still some uncertainty regarding the exact timing of the passage of storms, it’s likely that more intense storms will continue into the evening hours and potentially through the overnight as the cold front advances through the region.

Strong wind gusts, large hail, torrential rainfall, and even a few tornadoes are possible on Thursday. Stay weather-aware for watches and warnings in your area as this severe weather event unfolds.

With the likelihood of severe storms throughout the province, it is important to have a plan in place. Secure loose objects outdoors like patio furniture, ensure phones and electronics are charged, and have a plan to quickly seek safe shelter if warnings are issued.

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.

Warmer than normal temperatures are expected to dominate through the end of the month, but quick shots of cooler weather near seasonal, are also possible.
