Thursday marks the 7th and last day in a week-long heatwave that has claimed at least 33 lives in southern Quebec. The city has put in place emergency measures to assist those most at risk, but Urgence Sante is still reporting a 30 percent increase in calls, many directly related to the heat. Most municipalities have lengthened pool hours and established cooling centres. City of Montreal firefighters have been going door to door in many neighbourhoods to check on residents.

Temperature records have been falling across the province, with some locations establishing new all time record highs. Another temperature record, the third this week, was set on Wednesday in Montreal, as the mercury soared to 34.2C (94F) at Trudeau Airport. The previous record was 33.1C (91F) set in 1983. Other parts of the city were even warmer, I recorded a high of 34.8C (95F) on L'Ile Perrot. Montreal is expected to set another record today, with a forecast high of 35C (95F). Humidex or real feel temperatures will soar into the middle 40s.Widespread heat warnings and advisories remain posted from Ontario east through Quebec and into Atlantic Canada and south into New York and New England.

Numerous municipalities have imposed water bans or asked their residents to avoid watering lawns or washing cars. The blazing sun is starting to take a toll on browning lawns and trees, with leaves falling to the ground as if it was September. Conditions are dry, with less than 15mm of rain falling at Trudeau Airport since June 19th. Some relief is on the way as early as this afternoon. A cold front will move across Ontario and into Quebec in the wee hours Friday morning. Some pulse type thunderstorms are expected to pop up this afternoon around Montreal. The biggest threat is expected to be strong winds, dangerous lightning and torrential downpours. More storms are expected along the cold front overnight in Montreal, before cooler, more refreshing air arrives. On Friday, the heatwave will break, with clearing skies, lowering humidity levels, and a high temperature of 23C (73F). On Friday night, the temperature will drop below 20C (68F) for the first time in over a week, with a forecast low of 12C (54F). Mother Nature will be providing the natural A/C.
