Diving temperatures will chill Atlantic Canada before late-week storm Digital Writers Monday, January 18th 2021, 6:33 pm - After some lingering snow Tuesday, eyes turn to a late-week storm that threatens significant snow over Newfoundland. Conditions will remain unsettled for parts of Atlantic Canada Tuesday, with some lingering snow for the region, courtesy of weak systems passing through and sea-effect once they depart. Temperatures will take a considerable dive this week as a pattern change will send a shot of Arctic air into the region. Wednesday is forecast to be the coldest day since February 2020 for parts of the soutnern Maritimes. Beyond, there is the potential for a potent storm to impact parts of Newfoundland late week, threatening significant snow into the weekend. More on the impact and timing, below.
