Regina: This week, the Prairies are dealing with some pretty thick fog. It started off with low visibility, and Environment and Climate Change Canada had to issue fog advisories.
Some areas saw the fog lift by Monday afternoon, but don’t get too comfortable. It’s expected to roll back in overnight Monday into Tuesday, and some places will see it again Tuesday night.
On Tuesday morning, the fog will be hanging around, making driving a bit tricky. ECCC warned that travel could be hazardous due to the reduced visibility, so if you’re hitting the road, be ready for some near-zero visibility.
So, what’s causing all this fog? Well, milder air is moving over the snowpack, which cools down and creates fog as the ground cools the air above it. Lighter winds are keeping the fog in place, while stronger winds in southern Alberta are keeping that area clear.
Looking ahead, it’s going to stay mild through Christmas and the last week of December, with temperatures feeling more like November—up to 10 to 20 degrees above what we usually expect this time of year, especially near Hudson Bay.
There aren’t any big storms on the horizon for the weekend, except for the Rockies, where they’ll be getting a lot of snow from the storms coming in from B.C.
But don’t get too cozy; winter is set to make a comeback in early January. A much colder pattern is expected to settle in during the first few days of the month and stick around for a while, with the potential for some serious cold.
