Environment Canada says a significant 91Ƶarctic blast91Ƶ will sweep through the Okanagan and Shuswap as early as Wednesday evening, Jan. 10.

Daytime tempertures will plummet to -10 to -17 C and overnight lows are expected to flirt with marks of around -20 C, from Jan. 11 to 15, as a result.

91ƵIt91Ƶs really into Thursday (Jan. 11) where we91Ƶll see those temperatures significantly below normal,91Ƶ Environment Canada meteorologist Alyssa Charbonneau said, adding that the Okanagan will experience daytime highs of between -12 C to -15 C through the weekend. 91ƵIt91Ƶs definitely going to feel extremely cold to people, especially because we haven91Ƶt seen anything like it this season.91Ƶ

Overnight temperatures in Kelowna, Vernon, Penticton and Salmon Arm are expected to hit lows of -20 on Thursday, Jan. 11. That91Ƶs around 12 degrees colder than it usually is at this time of year, Charbonneau said.

This week91Ƶs cold snap comes after a warmer-than-normal start to winter. Cities in the region, , have felt the impact of the El Niño weather phenomenon since June, resulting in a notably mild and dry December.

91ƵWhat we91Ƶll see here with the cold isn91Ƶt unusual for this time of year,91Ƶ the meteorologist added. 91ƵI think what was unusual was just how warm December really was.91Ƶ

Below-seasonal temperatures are on their way, but it appears the Okanagan will actually avoid the worst of what91Ƶs to come in some parts of B.C.

On Tuesday, Environment Canada issued a forecast note stating parts of the province could welcome overnight temperatures of between -30 C and -40. Charbonneau says those frigid marks are most likely reserved for across the Cariboo region and towards Prince George.

91ƵFor the Okanagan, it91Ƶs not looking quite that cold, however, we haven91Ƶt seen anything close to this so it91Ƶs going to be a big change.91Ƶ

Unlike the , cold temperatures in the region this week are not expected to be record-breaking for this time of year.

Kelowna, for instance, recorded a temperature of -25.6 C on Jan. 12, 1950. That still stands as the city91Ƶs daily minimum for that day, the meteorologist said.

91ƵAt this point, the lows we91Ƶre going to see aren91Ƶt in record-breaking territory yet, but you can91Ƶt rule it out until we get through this week,91Ƶ Charbonneau added.

Beyond Monday, Jan. 15, Environment Canada says temperatures will begin to 91Ƶmoderate91Ƶ and return closer to seasonal.

91ƵIt doesn91Ƶt look like this extreme cold is going to last through next week,91Ƶ Charbonneau said. 91ƵStill, we91Ƶre in for four days of very cold weather.91Ƶ

Snowfall, meanwhile, remains in the forecast for Kelowna and Vernon on Tuesday, Jan. 9. Both cities could see another 2 to 4 centimetres fall through the night.

A 30 to 60 per cent chance of flurries remains penned for Penticton through Friday, Jan. 12.
