Montreal Snowstorm - March 7th, 2011

This is a small video compilation that I had made with respect to our third major snowstorm that influenced much of southern Quebec on March 7th, 2011.

Over the first weekend of March, the first of two major systems generated copious amounts of rainfall and some snow/patchy freezing rain previously, as temperatures rose progressively Saturday, March 5th. As the system departed, winds shifted from the North to NNW, causing the rain to change over to snow early Sunday morning, March 6th, resulting in about 4.4 cm of snow. The center of the second low pressure system tracked closely to the East and eventually NNE, causing an enduring wave of snow starting at 1:00 a.m EDT, March 7th and ending during the early afternoon hours. Temperatures dropped off to -17 C overnight Monday as an area of high pressure moved through.

This video first shows some composite radar imagery, providing you with an idea as to the dynamics of the storm system - large amounts of snow North, West and SW of the warm front, while flash-flooding rains took place along the East coast of the U.S. Radar looping is set to 10 minute intervals. If you examine the track of the system and the extent of the snow band, you can see that areas East and NE of Montreal (red dot) received a great deal more snow - the Eastern Townships, for instance, locally received as much as 70 cm of snow. The heavy bands of snow on the radar (dark blues) represent snowfall intensities of about 1-1.5 cm per hour. Tornadoes were also reported in the U.S South with the same system. The other sections of the video briefly depict the heavy blowing and drifting snows.

I am now monitoring a Colorado Low that may potentially generate as much as half a foot of snow before a transition over to ice pellets/freezing rain to rain. This storm could also set the stage for severe thunderstorms and tornadoes in the U.S South/SE for today through Wednesday, March 9th, 2011. As this system fuses with a system coming from the West, an Alberta Clipper, it will result in enduring instability for this coming second weekend of March.

Thank you for your viewing!

Great video Travis! Always great work and documentation of these weather events! We got hit hard this winter with historic proportions of snow, and it looks like you are getting your share of snow too. Your video shows many things of a winter storm. People out and about clearing off their sidewalks, and snow being removed, along with people getting stuck out there in the deep snow. Great job!

I appreciate your comments on my videos Travis! I will pay you back my friend!
