A nor'easter will track off the Eastern Seaboard and pass just south and east of Sable Island on Saturday, before approaching the Avalon Peninsula in Newfoundland on Sunday morning.

The passage of that weather system will bring periods of snow to Nova Scotia — heavy in the northeast — along with high and gusty northerly winds to start the weekend.

Increasing cloudiness across the province will begin this evening. Near or shortly after midnight, snow will begin to fall along the Atlantic coastline of the mainland.

The snow will be filling in east to west, moving in off the Atlantic as the nor'easter first approaches, then move past the province.

Winds will turn northeast tonight and increase to 30 km/h, gusting to 50 km/h. Low temperatures will be between –8 C and –5 C.

Snow will spread across Nova Scotia on Saturday morning, becoming heavy for Halifax County east of Porters Lake, as well as Guysborough, Pictou, Antigonish and Cape Breton.

Those areas can expect totals as high as 20 to 35 centimetres and are under a winter storm warning issued by Environment Canada.

Much of the rest of Nova Scotia will see 10 to 15 centimetres of snow with amounts tapering to near five centimetres for the Annapolis Valley and Cumberland County.

Skies will clear Saturday night with low temperatures of –10 C to –6 C.

Mostly sunny for Sunday. High temperatures will top out at 4 C to 0 C across the province.
