40 deg C this week in Ontario...Yikes
Folks in Ontario and Quebec will want to avoid strenuous activities in the outdoors this week, especially if they are vulnerable to the heat, as temperatures and humidity will soar to dangerous values.
We're just days away from the summer solstice, and Ontario and Quebec are getting an early head start on the season. Tuesday through Thursday will see the heat peak as daytime high temperatures jump into the lower to middle 30s. Humidex values will be even higher, expected to soar into the mid-40s in the Greater Toronto and Hamilton Area, in and near Ottawa, and across Montreal.
The heat and humidity will also fuel daily thunderstorm risks, so people will need to be weather-aware.
This week’s heat wave could break records across Ontario and Quebec as a strong ridge of high pressure builds over the eastern U.S. and the Great Lakes.Air sinks beneath a strong ridge, warming up as it descends toward the surface. Hot, muggy winds blowing straight from the Gulf of Mexico will add tropical humidity to the mix.Toronto-Pearson could rival its all-time highest June humidex value on record. The current monthly record is 45.6 set on June 30, 2018. The highest humidex forecast this week tops out at 44.
This level of heat could cause heat-related illnesses in even healthy individuals.Hot days running into stuffy nights will compound the effects of high heat on the human body, resulting in an increased potential for heat exhaustion and heat stroke. Simply circulating air with fans won’t be enough to provide necessary relief from this level and duration of high heat. Air conditioning is a vital survival tool during a days-long heat wave. Take advantage of community cooling centres if they’re available. Stay well-hydrated throughout the week, and avoid strenuous work outdoors during the heat of the day.
