Scorching temperatures and humidex advisories stretch from southern Ontario to the Maritimes today, with some areas feeling like it's over 40 c for the second straight day, and it looks like the heat will continue for a few more days.
"We’re in for at least another two or three days, forecast models, in fact, still have temperatures into around the low 30s through Wednesday, Thursday," CBC meteorologist Claire Martine said Tuesday night.
However, Martin added that the weekend would finally be a bit cooler.
As of Tuesday evening, Windsor's humidex was till hovering around 40 C as other parts of Ontario and southern Quebec remained in the high 30s.
It was a record-breaking heat wave for much of the Maritimes. St. Johns, NL., saw temperatures into the 30s and Port-aux-Basques, NL., broke a record set in 1911.
"The reason is an area of high pressure, known as the Bermuda high, is making its way in from the Atlantic and that’s allowing this very warm air to build its way up in through Ontario, Quebec and out in Atlantic Canada," Martin said.
The eastern half of the country say very warm and muggy conditions Tuesday.
Southern and eastern Ontario and southern Quebec had humidex values around and in excess of 40 C, with slightly cooler but still hot and muggy weather in parts of New Brunswick and southern Nova Scotia.
Montreal, Toronto and Ottawa saw highs of 31 C, 33 C and 34 C, respectively, with temperatures feeling over 40 with the humidex. The humidex in Windsor, Ont., had already hit 40 C by 11 a.m. ET.
Environment Canada issued a High Heat and Humidity Warning for parts of southern Quebec including Montreal, and Toronto's Medical Officer of Health upgraded the heat alert started Monday to an extreme heat alert.
"During an Extreme Heat Alert, call or visit family, friends and neighbours, especially isolated adults and seniors who are at greater risk of suffering from heat-related illness, to make sure they are OK," the city advises.
Given the humid conditions, pop-up thunderstorms are possible in both Quebec and Ontario, CBC meteorologist Jay Scotland said.
Scotland said he expects the heat and humidity to break by Saturday.
