HALIFAX -- Late Saturday, a developing low-pressure system will move off the eastern seaboard of the U.S. passing first south and then east of Nova Scotia on Sunday. While not moving directly through the Maritimes the system is forecast to come close enough to bring an accumulating snowfall to the region.

Snow, or a mix of rain and snow, is expected to begin late Saturday night for Nova Scotia while New Brunswick and Prince Edward Island see flurries. Snow will be steady for parts of Nova Scotia through much of Sunday while lighter snow falls for southern New Brunswick and P.E.I.

forecast timeline

Snow is forecast to fall steady for much of Nova Scotia on Sunday. Lighter snow and flurries for parts of PEI and New Brunswick.

Much of mainland Nova Scotia can expect five to 15 centimetres of snow in total. Areas closer to the Atlantic coastline beginning in Queens County and extending all the way into Cape Breton have the best chance of seeing the higher range forecast. Eastern Halifax County as well as Guysborough, Richmond, and Cape Breton Counties may hit a higher range of 15 to 25 cm. Lighter snow for P.E.I. and New Brunswick will add up to amounts ranging from a dusting to between two and 5 cm.

Snowfall Outlook

While some uncertainty in the snowfall forecast still exists it looks like the most snow will fall for eastern areas of Nova Scotia.

There is some uncertainty in how close the low will get to coastal Nova Scotia as it moves past. Should the low come in closer the higher snowfall amounts would become more widespread in Nova Scotia. Should the low hold further offshore snowfall amounts will be reduced as more will fall over the ocean.

Wind will increase through the day on Sunday peaking with gusts from the north and northwest of 40 to 70 km/h with the strongest around the Atlantic coastline of Nova Scotia. That will be enough to get falling snow blowing around further impacting visibility. Much like the snowfall forecast, the wind forecast will increase if it starts to look like the low will move in closer to the coast. 

Gust Forecast

Winds will increase from the north and northwest as snow fall on Sunday. The combination will lead to areas of blowing and drifting snow.
