LOOK AHEAD: SUMMER-LIKE WARMTH WITH HUMIDITY, STORM RISK

Summer-like weather will dominate the region until the end of the week, though cooler for lakeshore areas, with widespread mid and upper 20s for areas away from the cooling influence of the Great Lakes. The weather will become very humid across southern Ontario for several days, with occasional showers and thunderstorms.

“We’ve got heat and humidity that’s going to be building in and areas could actually be feeling like the upper 30s, close to 40,” says Weather Network meteorologist Kelly Sonnenburg.

A strong cold front will cross the region late in the week with a period of rain and thunderstorms, some could be strong, followed by cooler weather for the final weekend of May and into the first week of June.
