Much like Ontario, Quebec is facing a prolonged period of extreme heat and humidity. Conditions won't improve Sunday, with another day of daytime highs near, at or above the 30-degree mark, coupled with feels-like values approaching 40 for many. In addition to the intense warmth, the province is facing another threat for thunderstorms, though the chance has diminished quite a bit from Saturday. Some areas close to the Ontario border may even see some reach severe limits. Beyond, Quebec is set to bake in sweltering temperatures for a few days, yet. A closer look, ahead.

SUNDAY: EXTREME HEAT WON'T BUDGE, SEVERE STORM RISK RETURNS

A system tracking in northern Quebec will allow much of the province to remain in the warm sector Sunday. As well, it could fuel thunderstorms Sunday afternoon, though the risk is considerably less than on Saturday. The western half of the province may see storms fire up.

Areas that could see them will extend from northern Quebec down to south of the St. Lawrence, with just a small swath near the Ontario border that could see severe thunderstorms. Montreal is right on the cusp of the severe risk, but outside of it.

However, if storms do become severe, the main threats will be strong winds, large hail and heavy rainfall.

In addition to the storm threat, another sticky, hot day is expected Sunday with daytime highs near, at or above 30°C for many communities. To make it worse, the humidex will make it feel closer to 40.

HEAT, HUMIDITY LOCK IN FOR SEVERAL DAYS

Beyond the weekend, daytime highs will remain close to the mid-30s are possible next week, with the humidex pushing the upper 30s and even lower 40s at times.

There's the chance for widespread thunderstorms mid-week, but there is still uncertainty on the timing of the cold front as it sinks south. Overall the week looks to remain dry.

Relief from the high heat and humidity will arrive late week and hang on into the weekend, as cooler but seasonal temperatures return, with much lower humidity, behind the cold front.

However, new temperature records are likely to be broken before then for the longest stretch of 30°+C days so early in the season.
