Cooler temperatures expected for the week. Nelson, for example recorded its coldest temperature of -11.9 C back on Dec. 17, 2016 when the previous arctic air mass was in place. Our forecast overnight low would break this by six degrees!
A frigid start to 2017 for British Columbia. Here’s why.
Winter revellers rejoice!
Another extended period of chilly conditions is on tap for all of British Columbia next week, as cold, Arctic air once again infiltrates through the Rockies and makes its way all the way to the Pacific Ocean.
Daytime high temperatures will struggle to get above the freezing mark anywhere across the mainland throughout much of the week, and give bone-chilling overnight lows in the -20s to parts of the Interior.
Even cities on Vancouver Island will not be spared from the cold, as overnight low temperatures are forecast to drop below zero by mid-week.
Cold but clear week ahead
Despite the cold, conditions are forecast to be mainly clear and sunny throughout almost all of next week across the province. This is because the incoming arctic air is very dry, making it almost impossible for any clouds or precipitation to form.
It is only toward the end of next week when a coastal system is forecast to bring moisture from the Pacific Ocean ashore, leading to widespread snowfall as this moisture interacts with the cold Arctic air in place.
Not surprisingly, if coastal cities are forecast to drop below zero, you can absolutely count on some of the coldest temperatures in the province being felt (or endured) in B.C.’s Interior. Just look at some of these forecast overnight low temperatures for a selection of cities:
It is expected that this incoming arctic air will be the coldest of the season for some cities. Nelson, for example recorded its coldest temperature of -11.9 C back on Dec. 17, 2016 when the previous arctic air mass was in place. Our forecast overnight lows would break this by six degrees!
Meanwhile, Kamloops and Kelowna are forecast to experience a bit of déjà vu, as overnight lows next week will be very similar to the -18 to -22 C range that was felt during Dec. 12-17, 2016.
“Colder than normal” conditions?
Although extended periods of cold temperatures are no longer unfamiliar to B.C. residents this winter, you might be wondering whether or not these very cold conditions are “normal” for this time of year; after all, the past few winters have been much more mild, haven’t they?
