Mass of Arctic air invades parts of Canada, sends mercury plunging
FREDERICTON — A mass of cold air that meandered south from the Arctic has sent temperatures plunging across parts of Canada from New Brunswick to eastern Alberta.
Peter Kimbell, meteorologist with Environment Canada, says winds circulating from west to east cause Arctic air to occasionally invade the southern latitudes for a few days before retreating north.
Extreme cold warnings are in effect across the country, with temperatures feeling like -40 C in parts of Alberta, -45 C in Saskatchewan and Manitoba, and down to -50 C in northern Ontario.
Meteorologist Jill Maepea says a weather system that developed over the United States eastern seaboard brought about 25 centimetres of snow by the morning to southern New Brunswick, and about 15 cm to parts of Prince Edward Island.
