Montreal Weather Forecast: Sizzling Summer and Thunderstorms

Summer heat has been building across southwestern Quebec since last week, with Montreal expecting its hottest day of the year so far on Wednesday.

The city is expecting a daytime high of 31 degrees Celsius, and the humidity will make it feel more like 37 C.

While the reading is well above average, it is not a record.

The record for May 22 is 32.6 C in 1977, while the normal maximum is 20 C.

Wednesday should feature a mix of sun and clouds across southwestern Quebec, but an aggressive cold front approaching from the west is expected to bring severe thunderstorms.

The front should extend across the western sectors of the province by Wednesday afternoon.

Environment and Climate Change Canada has already issued severe storm warnings for the region with the possibility of heavy downpours, damaging winds and large hail.

The agency also reminds people that strong storms can produce tornadoes.

The same tracking system in the province was responsible for an outbreak of deadly tornadoes in Iowa.

Thunderstorms could develop in Montreal during the afternoon hours.

Behind the front, temperatures are expected to gradually drop through the end of the week, but should recover over the weekend.

Rain is expected early next week with cooler air on the way.
