Quebec to see snow from major storm as Arctic air dominates
A U.S. winter storm is set to bring some snow to southern Quebec early next week, driven by Arctic air and Gulf moisture fueling the system
Quebec will feel the effects of a major U.S. winter storm on Monday as moisture streaming north of the border interacts with the frigid Arctic air parked over the province.
Expect a challenging commute on Monday with very difficult travel amid heavy and blowing snow across the region.

Snow pushes into very cold airmass
Temperatures will be downright frosty across Quebec this weekend, with daytime highs in the -20s with overnight lows and wind chill values in the -30s.
A forecast high of -20°C in Montreal on Saturday may be the coldest we’ve seen in the city since Jan. 6, 2018.
The northern side of a powerful and potentially devastating winter storm in the U.S. will scrape southern Quebec with heavy snowfall. Expect precipitation to begin Sunday evening and continue overnight into Monday.
Initially, temperatures in the -20s will make for lighter snowfall. Snowflake formation becomes much less efficient at these bitterly cold temperatures because cold air hotels significantly less moisture.

We’ll see snowfall rates increase overnight into Monday as temperatures “warm” into the minus teens, which is a more efficient airmass for creating snowflakes.
Snowfall totals throughout the region will range from 5-15 cm, with heavier totals closer to the international border. However, despite the relatively low accumulations expected, the fluffy nature of the snow will lead to blowing and drifting.
Reduced visibility will make for dangerous travel throughout southern Quebec into Monday, likely affecting your Monday morning commute.
