Supercell Thunderstorm in Montreal - June 28th, 2010

A powerful squall line associated with a vigorous cold front advancing in from the Northwest (NW) at roughly 30-40 km/h brought with it a line of strong thunderstorms and heavy rainfall. Thunder and lightning were also witnessed as well as strong gusts of wind approaching 80 km/h. Before the storm came, from a distance, large scud were developing from beneath the shelf cloud, which provided some indication of the strength of the downdrafts. There were some lowering formations previously as well (refer to part 1 of this video), throwing hints for mesocyclone activity.

The video mostly depicts the strong gusts of wind and the accompanied heavy rains pelting on the window. Some pea-sized hail was also mixed in.

Two tornadoes were confirmed by Environment Canada with this squall line, one of which was in Saint-Anne-de-Bellevue (roughly 8 km Southwest of where I reside) and one just to the North of Montreal. Both tornadoes were registered at F0 strength (the weakest). Though at the lowest end of the Fujita scale, winds are, most assuredly, powerful enough to do some damage to trees (some large) and property.
