The polar vortex system that slammed Toronto with snow has one final parting gift for 2017: frigid temperatures that may break records, says Dan Kottlowski, a senior meteorologist at AccuWeather.

The Toronto temperatures aren’t cold enough to deter Boxing Day shoppers, even though its currently warmer in Iqaluit, but the next few days may have people rethinking their plans.

The polar vortex, which creates a pattern of “very, very cold air,” is leaving the Toronto area and heading into Newfoundland. Although it’s on its way to Eastern Canada, it’s leaving behind its “dirty work,”  said Kottlowski.

“The normal low for today should be around zero or just under and today’s low is much below that,” he said. “It’s like someone opened the freezer door and it’s stuck and won’t close until 2018.”

Tomorrow’s forecast may break the 1960 low of -18 C with an expected temperature of -22 C in the evening.

As for the rest of the week, Kottlowski expects it to be “bone-chilling cold,” with low temperatures expected to be in the negative teens and negative twenties range.

In terms of temperature highs for the next few days, tomorrow is expected to be -12 C, Thursday will be -13 C, Friday -9C, Saturday also -9 C and Sunday will be -12.
