Prairie Forecast Update: A few small tweaks

Update issued May 21, 2023, covering May 21-24, 2023

The weather models are continuing to do a good job with the short- to medium-range forecasts, but there have been a couple of small changes that have been slowly working into the forecast. Weak troughing off the West Coast is still forecasted to kick off the development of a leeside low in Alberta. This low […] Read more

Prairie Forecast Update: Forecast on track

Forecast issued May 14, 2023, covering the half-week stretch from May 14 to 17, 2023

The weather models have been remarkably accurate for this time of the year. The big weather picture remains the same. There is a large, persistent ridge of high pressure over far Western Canada with an equally persistent trough of low pressure over Eastern Canada. This means western regions will continue to see sunny, dry and […] Read more

November across the Prairies can run the full gamut of weather from summer-like conditions to the deep freeze of winter. Unfortunately, for most places this November, winter- like conditions mostly won out.

It was a cold start — will the rest of this winter be the same?

As usual, the forecasts are varied but none predict a warmer-than-usual winter this year

Reading Time: 4 minutes It’s hard to believe we are into the last month of 2022. From a climatological point of view, we have finished the first full month of winter across the Prairies. For those who are more astronomical, we are halfway through the first full month of winter. No matter which way you view it, November across the […] Read more


To get a red sunrise or sunset, you need a large number of particles in the air for the sunlight to bounce off, causing us to see more red light.

Red sky at night? Maybe. But snow from fog in August?

Our weather columnist analyzes some common sayings, and would like to hear some more

Reading Time: 4 minutes This summer I have crisscrossed this great country of ours. I started in early July heading east into the Muskoka region of Ontario to compete in an Ironman 70.3 triathlon. After spending a couple of weeks there, I returned home and did some quick gardening before heading west to Canmore for a wedding. What a […] Read more

The severe weather event feared by farmers and new-car owners alike

Alberta’s higher elevation makes it the hail capital of Canada

Reading Time: 3 minutes Let’s look at what is probably the most feared and costly summer severe weather event: hail. How expensive can hail be? To put it into perspective, on June 13, 2020, a severe hailstorm hit Calgary, causing an estimated $1.2 billion in insurance damage, which ranks as one of the top five most expensive natural disasters […] Read more


This map shows the percent of average precipitation across the Prairies during the 30-day period ending June 27. Both western and eastern regions received well above average amounts but the rains seemed to miss most of Saskatchewan, with a large portion of the province receiving well below average amounts.

Take your pick — there’s a forecast for everyone

Here are six forecasts for July and August, and they are all over the (weather) map

Reading Time: 3 minutes June seemed to go by in a flash. We are now halfway through 2022, and depending on where you live, it has been a very interesting six months. We will look back and see how June weather played out across the Prairies, and then look ahead to see what forecasters are calling for during July […] Read more

Heavy rain — where does all that water come from?

When a thunderstorm rolls in on a warm summer day, there’s an awful lot of water over your head

Reading Time: 3 minutes In the last issue we went into some detail on how thunderstorms develop, and how they can go from your average summer day thunderstorm to a severe thunderstorm. Thunderstorms can bring a wide variety of severe weather with them: heavy rains, hail, high winds, lightning, and, on some occasions, tornadoes. After an extended period of […] Read more


This map shows the amount of precipitation that has fallen across the Prairies so far this growing season as a percentile. The wettest region is around Edmonton, with precipitation amounts falling into the 90th to 100th percentiles. The driest areas are in southern Alberta and central Manitoba, with some areas seeing values as low as the 10th to 
20th percentiles.

Even in summer it’s cold up there — and that’s good

Reading Time: 4 minutes Last issue, we looked at how precipitation forms in warm clouds. But in reality, most of our summertime precipitation comes from thunderstorms, which primarily consist of cold clouds, so we’ll take a look at what cold clouds are and how precipitation forms in them. In general, a cold cloud is one that has at least […] Read more

This map shows the total amount of precipitation that has fallen across the Prairies during the first half of September. After a dry summer, central and eastern Manitoba along with northern agricultural Saskatchewan and the northern half of Alberta received some significant precipitation. These regions saw anywhere from 25 to more than 50 millimetres, providing some much-needed soil moisture.

An early spring provided a longer- than-average frost-free season

Many parts of Alberta saw earlier-than-usual fall frosts but had a pretty decent frost-free period

Reading Time: 3 minutes Every year around this time the weather discussion begins to centre around the first fall frost. Some years, like when we see an early-fall frost, this topic is at the forefront of conversations. This year, if you live in Alberta or Saskatchewan then there is a good chance that you’ve already seen your first fall frost […] Read more
