The Weather Network – The Atlantic provinces awaiting a duo of snow-capped systems in the coming days


Saturday, December 18, 2021, 4:20 p.m. – The first shot is Saturday night through Sunday, with difficult travel, particularly likely in Nova Scotia.

Winter weather appears to be reasserting itself in the Atlantic provinces over the next few days, starting with a tracking system south of the Maritimes that will bring widespread snow – the heaviest in Nova Scotia – through Sunday. Forecasters are already considering a second system for next week.

Newfoundland was suffering from persistent seaside snow on Saturday, but a heavier system moving south of the Atlantic provinces was expected to bring larger amounts to parts of the Maritimes starting Saturday night.

While most of the Maritimes will see amounts of it, the heaviest snow appears to be in Nova Scotia, the southwest of which could see up to 20 cm, with 10 to 15 cm for the Halifax area.

Atlantic snow

Halifax could see the heaviest strip of snow on Sunday morning, which will make travel difficult, before the system leaves late Sunday. Newfoundland appears to be dry and mostly cloudy, with minimal impacts from this system.


On Monday there is persistent snow, albeit with insignificant amounts, but Tuesday presents a second snow system for the region.

This will descend from northeastern Quebec, with widespread wet snowfall in the Atlantic provinces, but with a brief rainy warm-up. Newfoundland will see another set of seaside snow bands.

Near-term temperatures will look like single-digit negative numbers, with seasonally lower highs through Tuesday.
