Weather summary for Quebec issued by Environment Canada at 5:02 p.m. EDT Tuesday 20 June 2017. Discussion. The results of the investigations confirm that, at least, 3 tornadoes and a microburst affected the province of Quebec on Sunday June 18, 2017. In the wake of the severe thunderstorms that swept through the province of Quebec Sunday June 18, at least two people were injured and many damages have been reported. At least two homes were completely destroyed and several others were severely damaged. Blowdowns were observed in several locations across the province. Environment and Climate Change Canada's meteorologists were deployed to investigate selected sites. The following are preliminary results of the investigations. Full reports to come. Hebertville - Mont lac-vert: Environment and Climate Change Canada confirms that there was a EF2 tornado on the enhanced Fujita scale in the Hébertville, Mont Lac-Vert and Cascouia sound area. Following the examination of the damages caused by the tornado, the wind speed is estimated at about 180 km/h. The track is estimated to be about 3.5 km long. However, other damages and reports suggest that the track may have been near 10 kmlong. Further information would be required to confirm this hypothesis. We ask the public to report any damage along du parc road and du paradis road, between Lac-Vert and Cascouia sound; you can send your photos by email, at firstname.lastname@example.org, or by tweeting it with the hashtag #meteoqc. Sainte-Anne-du-Lac (Hautes-Laurentides, north of Mont-Laurier): Environment and Climate Change Canada confirms that there was a EF2 tornado on the enhanced Fujita scale. Following the examination of the damages caused by the tornado, the wind speed is estimated between 180 and 200 km/h. The track is estimated to be about 4.5 km long. Lac des Cornes, municipality of Chute-Saint-Phillipe (Hautes-Laurentides): Environment and Climate Change Canada confirms that there was a microburst which occurred over a distance of about 1.25 km. Following the examination of the damages, the wind speed associated with the microburst is estimated between 140 and 160 km/h. 20 kilometres south of L'Étape (Laurentians Wildlife Reserve): Environment and Climate Change Canada confirms that there was a tornado which force isn't known in the Laurentians Wildlife Reserve. No damages could be observed, thus it is impossible to predict how strong the winds associated with the tornado were. The tornado was identified after a radar analysis and a weather watcher reported the tornado by providing a video and photos. Environment and Climate Change Canada thanks the weather watchers, partners, media and the general public who provided us with photos, videos and other informations by sharing those on social media (#meteoqc) or by email, at email@example.com.

There’s no summary available but strong storms also affected parts of AB yesterday with high winds in the 80 – 100+km/h range being the primary impacts.
Red Deer has declared a local state of emergency as it deals with damage and power outages from the high winds.
The City of Red Deer declared a state of local emergency on June 20, 2017 due to widespread power outages caused by a severe wind storm. This gives the City to access additional resources including personnel and services from other levels of government.
The wind storm resulted in severe and widespread power outages which affected approximately 35% of residences across the city. Crews are working to restore power and clear downed trees across the city. The Water Treatment Plant continues to have power and water is safe to drink.
Update: June 21, 2017 at 1 a.m.
Electric Light & Power crews are assessing widespread power outages across the city. Some neighbourhoods may take longer to restore power due to the severity and volume of outages across the city. It may take up to two days to restore power to some areas. This is an estimate and may be subject to change.
Public Works crews are working to clear roadways and restore accessibility across the city. They remain focused on Red Routes (arterials) and Green Routes (collector roads). Crews will attend to Grey Routes (residential streets) over the next few days.
Parks crews continue to assess the state of City parks and trail systems.
The following parks and trail systems will be closed on June 21:
Great Chief Park
Some schools may be affected by power outages. Please contact the school board for more information.
There are some watches in place for SK related to the same complex moving through in a weakened state.
I’ll update this if a summary is made available in the future.
EDIT: EC has a summary available now.

There’s been relative stability from guidance with respect to the progression of the medium range pattern.
A broadly cool and active pattern should be in place through a wide swath of the country as troughiness steadily pushes east and upper ridging flexes in the west. Numerous disturbances of varying intensities could swing through the trough axis while drier conditions hold sway through SW BC.
