Last week of spring very summer-like in Montreal

While the spring thunderstorm season has been fairly tame in southern Quebec so far, such has not been the case in western Canada. Portions of Alberta and Saskatchewan reported large hail, heavy rain, powerful winds and even isolated tornadoes over the weekend. Over 10,000 lightning strikes occurred Saturday alone in Alberta, with winds gusting to 122km/h at Lloydminster. A peak wind gust of 135km/h was observed at Scott, Saskatchewan.

A cold front arrives on Wednesday, along with an increase in clouds, showers and thunderstorms. Expect a muggy high near 25C (77F). The balance of the week will see a return to sunny and warm weather, with high temperatures eventually reaching close to 30C (86F) by next weekend.
