Tuesday, July 7th 2020, 5:12 pm - Did your city or region make this year's June most memorable weather events?
June 2020 featured a prolific tornado outbreak in Ontario and other severe weather events that undoubtedly left an indelible mark on some Canadians.
June 2: The lightning show for the ages
Those across the Greater Toronto Area won't forget the incessant lightning that lit up the night sky in early June anytime soon. Unusually large hailstones impacted some regions in Mississauga, with strong winds contributing to localized power outages.
June 9: Tropical storm touches Lake Superior?
Fast forward one week and things got a little bizarre. By the evening of June 9th, the Weather Prediction Center issued updates on a Tropical Storm Cristobal in Wisconsin – an unheard of track for a tropical storm.
June 10: Tropical remnants fuel tornadic outbreak
The following day featured one of the more significant tornado outbreaks in southern Ontario in recent memory. After weeks of analyzing damage paths, seven confirmed tornadoes tore across Ontario, the strongest being an EF-2 in Mary Lake.
June 13: Catastrophic hail damage in Calgary
Just a few days later, some of the most severe hail damage Calgary has seen this century developed across southern Alberta, including damages to more than 20,000 homes across northeast Calgary. Damage estimates put this natural disaster at over one billion dollars in insurable losses.
June 28: Stationary thunderstorms inundated Brandon, MB
It's quite rare to accumulate an all-time daily rainfall total, but thunderstorm activity was exceptional and persistent for hours across the city.
When the storms finally relented, 155.5 mm of rainfall drenched the city, breaking the old record of 141 mm back in 1902 – but there's reason to think that value might be dubious.
June 28-30: Record warmth swept across northern Canada
During the last few days of June, the Canadian national hot spot pivoted around the shores of Hudson Bay. The temperature contrast along the shores of Hudson Bay varied dramatically with changes in wind direction.
Subsequently, the warmth spread to the most northern inhabited place in the world, Alert, Nunavut. Alert recorded an all-time June temperature record at 18.8°C.
As we turned the page into July, a stark contrast was evident on the available cloud cover data across the country. Prince Rupert, B.C. was enveloped in clouds nearly 90 per cent of the time, while Toronto shone through it's second sunniest month of the past seven years.
The persistent ridge of high pressure has pushed temperatures to the extreme, with drought conditions developing across parts of eastern Canada with significant forest fire risks, particularly in Quebec.
The dry weather also extended into Atlantic Canada as well with Halifax Airport recording it's third dried June on record.
