Another arctic blast on the way

As expected low pressure passing well south of Montreal pushed a little light snow into the southern suburbs overnight with 2-5cm from the South Shore to the US border. It was enough to push a transport off the road on Highway 20 south of the city closing that highway for several hours near Beloil. Montreal recorded only 3.2mm of snow, sleet and ice yesterday, but is was enough to make roads slick and travel slow.

This morning temperatures have cooled to -6C with light snow moving into the region again from the southwest as some energy crosses New York state. Look for a dusting to perhaps 2cm today. Arctic high pressure will then control our weather through the weekend with below normal temperatures. A blip on the radar will be a quick moving low pressure area on Friday that will pass from Ohio across New York and New England, with the potential to produce 5-10cm of snow from Ontario across Quebec with more off to the east. The really cold air will then pour into Quebec on strong north winds. Temperatures will drop into the -20's overnight and only rise into the minus teens during the day both Saturday and Sunday.
