Stretch of near-perfect summer weather for Montreal

Skies cleared on Sunday afternoon, providing ideal weather for the annual car show at Pointe-du-Moulin in Notre-Dame-de-L'Ile-Perrot. Unfortunately the threat of morning rain resulted in lower numbers of cars on display and patrons attending.

Monday will be as perfect a summer day as you can expect in Montreal in July. High pressure building in behind Sunday's cold front, will result in nothing but sunshine, low humidity, cooler temperatures and smoke-free skies. Highs will be in the low to middle 20s, cooling back into the lower teens by Tuesday morning, with even a few single digits possible outside the city. Winds should remain light.

This ideal summer weather will persist through Wednesday, before heat and humidity being to build again. Active weather returns by Thursday as higher humidity levels and warming temperatures nearing 30C (86F), will result in numerous showers and thunderstorms. The muggy weather will continue into Friday.

Over this past weekend, we had a few showers late Saturday into Sunday, but the front proved to be rather unimpressive for southern Quebec, a welcome relief after the flash flooding and thunderstorms of the past week. For the short-term, the hot and humid air has settled back south into the central and southern US, where millions are under heat advisories. Strong high pressure in those regions has resulted in a heat dome dominating the weather. Temperatures will soar into the middle and upper 30s, with humidex (real feel) readings over 38C (100F).

Along the periphery of the heat dome, slow-moving strong thunderstorms will continue to produce heavy rain and thunderstorms, in what is quickly becoming the summer of the flash flood across North America.

For now, that weather will remain to the south of Montreal and the St. Lawrence Valley. By next weekend, we are looking at pleasant weather once again, with perhaps the hot and humid weather pushing back north for the final days of July.
