Environment Canada says a significant 害羞草研究所渁rctic blast害羞草研究所� 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.

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

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

This week害羞草研究所檚 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.

害羞草研究所淲hat we害羞草研究所檒l see here with the cold isn害羞草研究所檛 unusual for this time of year,害羞草研究所� the meteorologist added. 害羞草研究所淚 think what was unusual was just how warm December really was.害羞草研究所�

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

害羞草研究所淔or the Okanagan, it害羞草研究所檚 not looking quite that cold, however, we haven害羞草研究所檛 seen anything close to this so it害羞草研究所檚 going to be a big change.害羞草研究所�

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害羞草研究所檚 daily minimum for that day, the meteorologist said.

害羞草研究所淎t this point, the lows we害羞草研究所檙e going to see aren害羞草研究所檛 in record-breaking territory yet, but you can害羞草研究所檛 rule it out until we get through this week,害羞草研究所� Charbonneau added.

Beyond Monday, Jan. 15, Environment Canada says temperatures will begin to 害羞草研究所渕oderate害羞草研究所� and return closer to seasonal.

害羞草研究所淚t doesn害羞草研究所檛 look like this extreme cold is going to last through next week,害羞草研究所� Charbonneau said. 害羞草研究所淪till, we害羞草研究所檙e in for four days of very cold weather.害羞草研究所�

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.
