An Exceptionally Warm May Across the Canadian Prairies

It was a very rapid transition from winter to summer this year on the Prairies. After a very cold first half of April, a very warm May ensued with mid summer-like heat in the second half of the month. Widespread parts of the Prairies recorded a top 15 warmest May, since records began. The warmth was most impressive, relative to normal, in Alberta and Saskatchewan where Regina had its warmest May on record and Calgary its 2nd warmest May. In southern Manitoba, the heat was also accompanied by unseasonably high humidity.

In terms of precipitation, it was near to slightly below normal in most parts of the Prairies, with eastern parts seeing precipitation closer to normal than in recent months. After a wet winter in Alberta (particularly southern Alberta), the weather turned slightly drier in May compared to normal, but nothing too exceptional.

Southern Manitoba Hail

Thunderstorm season is well underway across Canada. Manitoba has experienced some of the strongest thunderstorms thus far in 2018, with four severe thunderstorm days in May. At Weatherlogics, we maintain a database of quality-controlled hail reports across the country. So far this year, Manitoba has had around a third of all hail reports across Canada in what has shaped up to be an active start to the thunderstorm season.

Thursday, May 24 was the most significant hail day in May, with numerous reports of hail across southern Manitoba. Two rounds of thunderstorms occurred. The first was in the morning, which also caused strong wind gusts from Crystal City to Portage. A second round of storms in the late afternoon and evening brought more hail. The map below shows the exact locations where hail occurred. Note, we also keep track of hail size using a strict quality-control procedure.

Southern Ontario Severe Winds on May 4

An extreme wind event occurred in southern Ontario on May 4, causing extensive damage from Windsor to Ottawa. Widespread wind gusts over 90 km/h were recorded with a few cities recording gusts over 110 km/h. In some locations, these were the strongest wind speeds ever recorded in May. The image below shows some of the damage captured by the Peel Regional Police. In the second week of June, we plan to post a more in-depth summary of this event which will include the factors which combined to create such extreme winds.

Update on the Dry Conditions On the Prairies

Much of Saskatchewan and Manitoba saw beneficial rainfall in May, with precipitation totals finally being closer to normal. However, since a significant portion of that rain came from thunderstorms. Some pockets of southern Manitoba are still quite dry, such as extreme southwestern Manitoba, (around Melita) and parts of the Red River Valley. However, more rain is expected today (June 1), into tonight, throughout the region, which will help the region significantly. Southern Alberta (Calgary and eastward) experienced wetter than normal conditions earlier this year, but in May precipitation trended closer to normal as the storm track shifted away from Alberta. The map below from Agriculture and Agri-Food Canada illustrates the closer to normal precipitation amounts throughout most of the Prairies.
