A cold snap affecting Southern Ontario could transition into muggy, swamp-like conditions in the coming days, with some models predicting temperatures to soar into the mid-30s early next week.

Cold temperatures and stormy weather have put a damper on the late spring vibes in the province, though meteorologists expect a major heat wave to descend on the region next week. 

But before that happens, the province will get a little taste of that heat starting with a spike in temperatures this week.

Meteorologists at The Weather Network promise that warm temperatures will return to the province this week, with the caveat that it might be a bit too warm for some.

"Temperatures are set to steadily climb this week across Ontario, although it [may] leave you wanting to stay indoors with a fan or air conditioning," reads a report from the weather news outlet.

The scorching conditions are expected to begin on Thursday. Toronto is already expected to see daytime highs top out at 27 C, though humidex factors will make it feel like a sizzling 33 C.

Another cold front is expected to sweep in and interrupt the warm weather, only to depart in time for a major temperature spike to start next week.

According to European weather models, temperatures could reach the mid-30s starting on Monday, and persist throughout the week.

Still aways out, but the 🇨🇦 Model brings a sweltering heatwave to Southern #Ontario early next week.

Widespread temps in the low to mid 30s with overnight temps in the mid 20s for a couple days

The Weather Network's model predicts a slightly more tolerable week with temps in the high 20s, though even this model shows humidex values soaring into the mid-30s persisting until at least June 25.

Regardless of which weather model you trust, next week is shaping up to be the first significant heat wave of the year.
