Environment Canada says a significant 㽶Ƶֱarctic blast㽶Ƶֱ 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.

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

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

This week㽶Ƶֱs 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.

㽶ƵֱWhat we㽶Ƶֱll see here with the cold isn㽶Ƶֱt unusual for this time of year,㽶Ƶֱ the meteorologist added. 㽶ƵֱI think what was unusual was just how warm December really was.㽶Ƶֱ

Below-seasonal temperatures are on their way, but it appears the Okanagan will actually avoid the worst of what㽶Ƶֱs 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.

㽶ƵֱFor the Okanagan, it㽶Ƶֱs not looking quite that cold, however, we haven㽶Ƶֱt seen anything close to this so it㽶Ƶֱs going to be a big change.㽶Ƶֱ

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㽶Ƶֱs daily minimum for that day, the meteorologist said.

㽶ƵֱAt this point, the lows we㽶Ƶֱre going to see aren㽶Ƶֱt in record-breaking territory yet, but you can㽶Ƶֱt rule it out until we get through this week,㽶Ƶֱ Charbonneau added.

Beyond Monday, Jan. 15, Environment Canada says temperatures will begin to 㽶Ƶֱmoderate㽶Ƶֱ and return closer to seasonal.

㽶ƵֱIt doesn㽶Ƶֱt look like this extreme cold is going to last through next week,㽶Ƶֱ Charbonneau said. 㽶ƵֱStill, we㽶Ƶֱre in for four days of very cold weather.㽶Ƶֱ

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.
