This is a video showing a severe thunderstorm that moved through the Montreal area. This storm formed in association with a warm frontal wave of a vigorous low pressure system coming in from the West.

Convective available potential energy was very high in both southern Ontario and southern Quebec (which, in part, facilitates strong downdrafts), and wind shear was also ideal at low to high levels of the atmosphere (I detected using mesoscale analyses, provided by NOAA's model outputs), which helped the storm to become better organized while sustaining itself for multiple hours - as I tracked this storm, I observed that it traveled for nearly 200 km before dissipating once it moved East of Montreal. This storm produced a strong gust front, with downbursts of wind locally approaching 100 km/h, snapping large tree branches. I noticed some marble-size hail later mixed in with the lashing rains that came with the strong downdrafts. This storm had a history of rotation as it pushed East of Ottawa, but I didn't notice any distinct rotation at the time in my area, although the updraft region of the storm was very turbulent, as shown by the pattern of the shelf cloud.

This was taken in SW Pierrefonds, located in Montreal's West Island.
