With thunderstorms brewing in the soup of Montreal’s humidity, Environment and Climate Change Canada issued a severe thunderstorm watch Wednesday.

The storms — expected in the afternoon and into the evening — could produce heavy rain, the federal meteorological agency warns, which could cause flash flooding and reduced visibility on roads.

Similar alerts have been issued as far east as Repentigny, into the lower Laurentians and west to the Ontario border. In Ontario, a strip of weather warnings stretch to the Manitoba border.

The temperature will only hit 25 C on Wednesday, but the humidex is reaching for 32 C.

The average maximum temperature for June 10 is 22.6 C, with an average low of 11.7 C. We likely won’t break any heat records; the highest recorded temperature for the day was 31.7 C in 1959.
