Cool & rainy start to the week in Montreal

A rather vigorous low pressure area for late July is centered near Rochester, NY this morning. The system has a large area of rain and thunderstorms pivoting around it, and that area will move into southern Quebec and eastern Ontario this morning as the low moves towards Sherbrooke. It should be a rainy and cool Monday with even the chance for thunderstorms, temperatures will only be near 20C (68F) today and down to 15C (59F) tonight. The rain will be rather impressive with 25-30mm, around 1 inch generally throughout the region. Heavy rain is forecast across the Townships along with embedded thunderstorms. A rainfall warning is in effect for the Beauce and Eastern Townships where 60mm could fall. The rain should end by midnight. The rest of the week looks unsettled with showers and thunderstorms possible with a very slow warming trend.

On Sunday Montreal had about 17mm of rain, mostly in thunderstorms to start the day and scattered showers in the evening. We managed a muggy high of 25C (77F).

Thunderstorms produced major flooding in Toronto last evening with several roads impassable. (Global News)
The same system drenched southern Ontario on Sunday with 50-100mm (2-4 inches) of rain in thunderstorms. High winds cut power, trees fell on homes and cars and even a funnel cloud was reported in the southwest. Flooding occurred last evening on several major GTA highways including the 401. The OPP took to Twitter to recommend drivers stay off the roads and definitely not drive through standing water. The photo shows above some did not head that advice.
