Environment Canada says a significant 含羞草研究社渁rctic blast含羞草研究社� 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.

含羞草研究社淚t含羞草研究社檚 really into Thursday (Jan. 11) where we含羞草研究社檒l see those temperatures significantly below normal,含羞草研究社� Environment Canada meteorologist Alyssa Charbonneau said, adding that the Okanagan will experience daytime highs of between -12 C to -15 C through the weekend. 含羞草研究社淚t含羞草研究社檚 definitely going to feel extremely cold to people, especially because we haven含羞草研究社檛 seen anything like it this season.含羞草研究社�

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

This week含羞草研究社檚 cold snap comes after a warmer-than-normal start to winter. Cities in the region, , have felt the impact of the El Ni帽o weather phenomenon since June, resulting in a notably mild and dry December.

含羞草研究社淲hat we含羞草研究社檒l see here with the cold isn含羞草研究社檛 unusual for this time of year,含羞草研究社� the meteorologist added. 含羞草研究社淚 think what was unusual was just how warm December really was.含羞草研究社�

Below-seasonal temperatures are on their way, but it appears the Okanagan will actually avoid the worst of what含羞草研究社檚 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.

含羞草研究社淔or the Okanagan, it含羞草研究社檚 not looking quite that cold, however, we haven含羞草研究社檛 seen anything close to this so it含羞草研究社檚 going to be a big change.含羞草研究社�

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 city含羞草研究社檚 daily minimum for that day, the meteorologist said.

含羞草研究社淎t this point, the lows we含羞草研究社檙e going to see aren含羞草研究社檛 in record-breaking territory yet, but you can含羞草研究社檛 rule it out until we get through this week,含羞草研究社� Charbonneau added.

Beyond Monday, Jan. 15, Environment Canada says temperatures will begin to 含羞草研究社渕oderate含羞草研究社� and return closer to seasonal.

含羞草研究社淚t doesn含羞草研究社檛 look like this extreme cold is going to last through next week,含羞草研究社� Charbonneau said. 含羞草研究社淪till, we含羞草研究社檙e in for four days of very cold weather.含羞草研究社�

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.
