Another hot sunset in Montreal. The excessively hot and dry summer has taken a toll on trees and vegetation in the region. Many are showing signs of significant heat stress and lack of moisture. The hot weather has been historic in many parts of eastern Canada, with dozens of new temperature records established from Ontario to Newfoundland. Relief is on the way for southern Quebec Wednesday.
Severe Thunderstorm Watch issued for Montreal
The historic heatwave that has gripped the eastern part of Canada for nearly a week now will come to an end in Montreal Wednesday. A cold front is moving across Ontario as I write, with showers and thunderstorms developing in advance. Some of the storms may be on the strong side, with gusty winds and heavy rain the main threat. We need the rain, let's just hope it does not come all at once.
Tuesday was another sweltering day, with a record-breaking high of 34.6C (94.3F) at Trudeau Airport. It was the third consecutive day with record heat following Sunday's 34.4C (94F) and Monday's 35.1C (95F). Overnight lows have remained in the low to middle 20s. Montreal was still 29C (85F) at midnight early Wednesday.
Patly sunny skies Wednesday morning will give way to clouds, showers and thunderstorms through the noon hour and into the evening. Temperatures will be warm again today, reaching 30C (86F) before the rain. It will be a muggy day. The air behind the front will be cooler and less humid, with highs in the middle 20s expected Thursday and Friday.
The heatwave has resulted in watering bans being issued for several communities across southern Quebec. The wildfire risk has been high as well, with numerous significant fires being reported in Ontario and across Atlantic Canada and Newfoundland.
Dozens of new record highs were established over the last few days. Badger, Newfoundland reached 36.7C (98F) on Tuesday, a tie for the warmest temperature on record for the province. Miramichi, New Brunswick reached 38.6C (101.5F).
Montreal is also moving up the list for the warmest summer on record. As of Tuesday, we had recorded 10 days of 32C (90F) or higher. That places us fifth in the record books behind the 14 days recorded back in 2020.
The heatwave has sadly resulted in at least one heat-related death in Montreal, and there have likely been others. The prolonged effect of days of high heat is taking a toll on many. The cooler weather and rain will be more than welcome.
