A snowfall warning is in effect for the Okanagan with 5 to 10 centimetres expected to fall in Kelowna, Penticton and Vernon Sunday afternoon.
“This morning we have a low pressure system crossing the southern interior giving us some moderate snow passing through the Okanagan right now,” said Environment Canada meteorologist Eric Mak.
The Arctic front will bring bitterly cold air to the Okanagan. A special weather statement has been issued for the Central, North and South Okanagan.
“For the Okanagan, we are looking at a wind chill close to -26 for tonight,” Mak said.
Environment Canada’s forecast says it will feel like -16 C with the windchill in Kelowna and Vernon during the day on Sunday. In Penticton, it will feel like -10.
Temperatures will plummet this week to -16 to -25 C with the windchill during the day, while overnight lows will reach -26 across the valley.
It will be coldest in the Yellowhead, Columbias and Southwest Interior on Monday morning, according to the advisory, with wind chill values reaching -30 C.
Mak said the freezing temperatures will stick around until Friday.
“The Arctic air will settle down early next week and the earliest warm-up will be Friday with some clouds rolling in and the next system is expected to move in later on Friday,” he said.
Highway snow advisories
Snowfall warnings and blowing snow advisories have been issued for many B.C. Interior highway mountain passes.
Environment Canada says 15 centimetres of snow is forecast to fall on the Coquihalla Highway from Hope to Merritt, while drivers travelling along the Okanagan Connector are warned of blowing snow from Merritt to Kelowna.
“Visibility will be an issue, especially with blowing snow when visibility will be reduced greatly so I suggest drivers to be cautious when driving these highways,” Mak said.
The advisory says visibility may be significantly and suddenly reduced to near zero and drivers need to be prepared to adjust their speed with changing road conditions.
Highway 3 will receive 10 to 15 centimetres of snow at Allison Pass, the Trans-Canada Highway at Eagle Pass will receive 5 to 10 centimetres of snow and Highway 3 at Paulson Summit will receive 15 to 25 centimetres of snowfall on Sunday.
