Environment Canada says a significant ѻýarctic blastѻý 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.
ѻýItѻýs really into Thursday (Jan. 11) where weѻýll see those temperatures significantly below normal,ѻý Environment Canada meteorologist Alyssa Charbonneau said, adding that the Okanagan will experience daytime highs of between -12 C to -15 C through the weekend. ѻýItѻýs definitely going to feel extremely cold to people, especially because we havenѻýt seen anything like it this season.ѻý
Overnight temperatures in Kelowna, Vernon, Penticton and Salmon Arm are expected to hit lows of -20 on Thursday, Jan. 11. Thatѻýs around 12 degrees colder than it usually is at this time of year, Charbonneau said.
This weekѻýs 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.
ѻýWhat weѻýll see here with the cold isnѻýt unusual for this time of year,ѻý the meteorologist added. ѻýI think what was unusual was just how warm December really was.ѻý
Below-seasonal temperatures are on their way, but it appears the Okanagan will actually avoid the worst of whatѻýs 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.
ѻýFor the Okanagan, itѻýs not looking quite that cold, however, we havenѻýt seen anything close to this so itѻýs going to be a big change.ѻý
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 cityѻýs daily minimum for that day, the meteorologist said.
ѻýAt this point, the lows weѻýre going to see arenѻýt in record-breaking territory yet, but you canѻýt rule it out until we get through this week,ѻý Charbonneau added.
Beyond Monday, Jan. 15, Environment Canada says temperatures will begin to ѻýmoderateѻý and return closer to seasonal.
ѻýIt doesnѻýt look like this extreme cold is going to last through next week,ѻý Charbonneau said. ѻýStill, weѻýre in for four days of very cold weather.ѻý
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.
