Environment Canada has issued a Special Weather Statement advising that a cold Arctic air mass will remain over Nova Scotia today and tomorrow.
Cold temperatures combined with moderate to strong westerly winds will make it feel like minus 20 today and minus 26 to minus 30 tonight and tomorrow morning.
Environment Canada's Linda Libby explains where it's coming from.
"After that last weather system went through the area on Christmas Day, it allowed an Arctic ridge of high pressure to push southward into Eastern Canada and it's really influencing the weather here in Atlantic Canada"
Libby says the cold temperatures are expected to persist until the weekend but another system might bring warmer temperatures depending on its track.
