Colder weather is set to move in on Friday, as well, bringing frigid conditions for the weekend. Daytime highs across New Brunswick are forecast to drop near -20°C, with similar conditions extending into PEI and parts of Nova Scotia. Southern Nova Scotia will see temperatures in the minus teens.
Brace for impacts: Frigid air and heavy snow
A frigid Arctic air mass in eastern Canada will clash with a warm, moist air mass from the Gulf of Mexico, creating a boundary that will produce heavy snow and ice all the way from Texas to the Atlantic coast.
This weekend, the Maritimes will experience very cold Arctic air, with daytime highs ranging from minus teens to -20°C. Halifax is forecast to see a high of -14°C on Saturday — a rarity, last observed in February 2023, December 2016, and January 2014.
Wind chills could drop to -20 to -30 or lower.
