Weekend snow

First off Happy Thanksgiving to all our American friends. Secondly, the move is nearly complete, however thanks to Bell once again, our phone service is delayed. This means no computer connection at the moment from home.

Traditionally this is the time of the year where we begin to see our first accumulating snows in our region. This will be the case this weekend for many portions of Ontario, Quebec, New York and New England. Low pressure developing off the US east coast will move north towards the Maratimes. Steady rain will develop today in most areas with a gusty and chilly northeast wind. Tonight as the temperature lowers the rain will change to wet snow northeast of Quebec City and across the higher elevations of the Townships, Greens and Adirondacks. Look for between 15-25cm of wet snow to accumulate at the highest elevations. Additionally there will be gusty northwest winds developing on the back side of the system. These winds will exceed 50km/h and produce blowing snow. Environment Canada has posted a Heavy Snow Warning for the Townships while a Winter Weather Advisory is in effect for the Dacks and Greens.

In the lee of Lakes Huron, Erie and Ontario, a round of lake effect snow is possible late Friday into Saturday. In Montreal a cold rain today will taper off to a few flurries Saturday with a gusty Northwest wind of up to 60km/h.

If you are travelling south today for the US holiday or Black Friday, keep in mind that travel will become poor on many roadways across Vermont, New York and southern Quebec. The low pressure is expected to bomb out (rapidly intensify) near Portland, Maine tonight and move into Atlantic Canada with very strong winds and heavy precipitation.
