Up to 10cm of snow forecast for Montreal and Ottawa

Snow will advance into southern Quebec today. (AccuWeather)
This is just a brief update on the clipper system about to affect southern Ontario and Quebec. Light snow is advancing this morning across Ontario and will arrive in Ottawa by 10am and Montreal by the noon hour. This is not a big storm, clipper systems originate from the Prairies, so they are usually starved of moisture. The Great Lakes gives them a little kick, but in this case the system is weakening. It will morph into a big storm for the Atlantic provinces once it reaches the coast later tonight and strengthens rapidly.

Montreal can expect light snow through the afternoon and into the overnight with 5 to 10cm possible. Gusty winds, up to 40km/h, will likely cause some blowing snow, especially outside of the city. The snow will be enhanced a little as you head down the 401 towards Kingston. While there are no weather warnings on our side of the border, a winter weather advisory is in effect for the US side of the St. Lawrence River including Massena, New York. Keep this in mind if your travels take you onto the highway today. Temperatures will be cold with a high of -5C today dropping to -11C tonight.

Next Storm
We are watching a complicated forecast for this weekend that could include a significant snowfall for Montreal on Saturday. Twin low pressure ares will impact the region, but the exact track at this time is up in the air. Stay tuned!
