Severe cold settles into NB

ColdTemperatures could fall as low as -22°C in parts of New Brunswick tonight and it will feel even colder with the windchill.

An Arctic air mass has moved into the Maritimes and is expected to stick around for a few days.

How can it get so cold?

Cold air develops over frozen areas of the Arctic region.

At these high latitudes, there is little or no sunlight this time of year with far more outgoing than incoming heat energy.

Eventually the cold air moves south across North America and is giving us the first frigid conditions of the season.
