Anatomy of a cold snap

While the polar vortex is an important trigger for this phenomenon, it's not the only one

Reading Time: 4 minutes I’ve had a couple of really good questions over the last few weeks. One was very timely about the Polar Vortex, and the other was a question about the impact of volcanic activity on our climate, particularly the Tonga volcanic eruption back in January of 2022. Since the polar vortex question is a little more […] Read more

Prairie forecast: Stormy start in the east, slightly cooler west

Issued Feb. 7, covering Feb. 7 to 14, 2024

You can’t say it has been a strange and interesting winter. First, we saw a wintery end to October, then fall moved back in for most of November and December before we finally saw a big old shot winter in mid-January. Now we have been dealing with spring like conditions over the last two weeks – what’s next? Well, it looks like winter is going to try and make a comeback.

Officials say southern Alberta will be in good shape even if precipitation and runoff capture on the Oldman and St. Mary rivers are at median levels, but low levels could lead to a worst-case scenario.

Prairie forecast: Warm weather returns

Issued Jan. 24, 2024, covering Jan. 24 to 31

For this forecast period, it looks like our weather pattern will undergo a shift back to the mild pattern we experienced at the beginning of the winter. It also looks like the warm weather will stick around for at least a couple of weeks. The million-dollar question is whether we will see another outbreak of cold arctic air, or will we see an early start to spring? Well, if I knew that answer to that, I would be rich, but I don’t think winter is over quite yet.

Prairie forecast: More typical mid-winter weather

Issued Jan. 17, covering Jan. 17 to 24

For this forecast period it looks like it'll simply be winter--not bone chilling cold, but not springtime warm. The general pattern that appears to be developing across the prairies is showing warm air trying to push northeastwards out of the western U.S., but with a northwesterly flow across the prairies, it looks like there will be a parade of cold, arctic high-pressure systems dropping southeastwards every few of days. The question is, just how far north will the warm air push, or for far south will the arctic air push?
