A low pressure system and cold front will cut into the sultry air that lies over Quebec and Ontario. That front is forecast to bring strong to severe thunderstorms Sunday from noon into the evening hours. Hail and heavy rain will be the main threat here in Montreal, but strong winds are also possible. Today was just another hot summer day in Montreal with the mercury hitting 33C (93F) at Trudeau Airport but as warm as 35C (95F) downtown and off island to the southwest in St Anicet. Heat and humidity advisories are in effect for the entire region from Montreal to Windsor and north to Ottawa. Humidex values touched 40C here in Montreal and as high as 43C in St. Anicet. Even at this late hour in the evening it remains warm in metro Montreal at 28C (83F).
