An early look at next week's storm potential in eastern Canada
Friday, January 16, 2015, 2:10 PM - Potential is increasing for a winter storm to affect eastern Canada early next week, bringing the possibility of heavy snowfall for Quebec, as well as strong winds and rain for the Maritimes. Here’s a look at what the latest forecast guidance shows for this system.
Initially, a clipper system will track out of the Prairies on Sunday, leading to the potential for widespread light snowfall across Ontario and Quebec (on the next few images, blue areas represent snow, while green represents rain).
Sunday night a new area of low pressure will form along the U.S. coast. This new system will phase with the original storm and strengthen as it tracks northeast.
As the storm intensifies, it will bring heavy winds and rain to the Maritimes, as well as likely producing a band of heavy snow across the St. Lawrence Valley through the day on Monday. The exact placement of the rain/snow line will be an important forecast challenge with this system.
As the storm continues to track up the coast, the primary impacts for Newfoundland and Labrador should be during the day on Tuesday, shown on the image below.
