***I STRONGLY RECOMMEND USING EARPHONES/HEADPHONES (BASS AMPLIFIED) TO HEAR THE MORE NATURAL SOUND OF THE RAIN***
A video compilation showing a strong multicell thunderstorm that affected largely areas just South of the island of Montreal, but also briefly the extreme Southern portion of the West Island.
The thunderstorm was associated with a stationary front and shortwave trough. Deep shearing fields were fairly weak, as were mid-level cooling rates, but the degree of shear was sufficient for at least some organized convection for the late-evening to overnight period. Due to weak wind shear, thunderstorms were fairly slow-moving. Instability was largely maximized by very high humidity and significant solar heating following early-morning heavy rainfall and cloud cover associated with a stationary warm front and shortwave at that time. Mid-level cooling rates also reached marginally steep standards before weakening by late-afternoon, increasing instability.
The footage first highlights the early-day heavy rainfall, followed by a late-afternoon distant thunderstorm, and then the late-evening to early-overnight thunderstorm that briefly affected the Southern portion of the West Island.
Footage was taken in SW Pierrefonds, located in Montreal’s West Island. Radar imagery is courtesy of NOAA.
