Canada’s record-setting wildfires could persist for rest of ‘marathon’ summer

Country's fires account for over a quarter of world's carbon for 2023

Ottawa | Reuters — Record-setting wildfires in Canada could potentially continue burning at an abnormally high rate for several more weeks, though the spread of blazes is likely to start diminishing in September, according to federal projections released on Friday. Forest fires have engulfed parts of nearly all 13 Canadian provinces and territories this year, […] Read more

This graphic shows the average global temperature from July 1-23 from 1940-2023. July 2023 is on pace to be the hottest July on record globally.

Heat waves: sunshine and sinking air

Temperatures above 30 C have cropped up a lot this year, but what makes up an official heat wave?

Reading Time: 3 minutes Glacier FarmMedia – Let’s continue our look at severe summer weather by examining heat waves. While we have seen recent hot weather, it pales in comparison to some of the extreme heat reported in other parts of our planet this July. Heat waves have enveloped large portions of the Northern Hemisphere, bringing record-breaking heat to […] Read more

Prairie Forecast: Cooler and unsettled

Issued Aug. 9, covering Aug. 9 to 16

First off, I must apologize for not producing an update to the last forecast; I had the opportunity to do some backwoods camping, which meant I was off the grid for about five days. I’m back now, and from the weather model runs I’ve been able to check out, this forecast period is going to […] Read more

Prairie forecast: Warm-hot start then slow cooldown

Issued August 2, covering August 2 to 9

The weather models have been doing a good job with the overall weather picture over the last several weeks, despite a fairly unsettled, tough-to-figure-out weather pattern. In this next forecast period, it will again be tough to figure out some of the finer details as our region experiences weak highs, lows, and even the possibility […] Read more


Thunderstorms are a fact of life in Alberta, but severity is due to a combination of factors.

The ingredients for a severe summer storm

Air temperature and movement determine whether it will be a storm to remember

Reading Time: 3 minutes What turns a regular thunderstorm into a severe thunderstorm, or occasionally, into a thunderstorm that you truly remember? First, there is a hot humid air mass in place, the air a few thousand feet up is very cold, providing for good lift, and there is a strong jet stream overhead to provide venting at the […] Read more

For longer duration events, the climate change signal tends to be weaker and more variable.

Opinion: Why climate change isn’t always to blame for extreme rainfall

Warm air holds more moisture, but not all catastrophic rain events are due to a warming globe

Reading Time: 3 minutes Extreme rain and floods can trigger a flood of another sort — claims that climate change is to blame. But these claims are not always well founded. In our new paper in Nature Geoscience, we discuss what can and can’t be attributed to climate change after extreme rain events. We use the floods of early […] Read more

Updated prairie forecast: unsettled start as sub-arctic high builds in

Issued July 26, covers July 26 to August 2

Update: A low tracking through central prairies is a little weaker than expected. This will result in less precipitation with showers, thundershowers, and storms being less widespread. Another issue is the smoke which can be difficult to predict. Areas with smoke we see cooler than expected daytime highs. An upper ridge that brought plenty of […] Read more

Ranchers in Alberta’s Special Areas say pastures had gone brown even before the grasshoppers arrived.

Drought and infestation woes grow throughout province

Special Areas is latest jurisdiction to declare agricultural state of emergency

Reading Time: 6 minutes Grasshoppers have been chewing their way through hay and other crops all over southern and central Alberta. But in some areas, even grasshoppers have nothing to eat in dry pastures and hay fields. That’s the case with southeast Alberta rancher Brad Osadczuk. And he’s not alone. “I think grasshoppers are looking for green vegetation and […] Read more

Prairie Forecast: Summer heat to build back in

Issued July 19, covering July 19 to 26

It looks like the overall weather pattern is going to undergo another shift. After nearly two weeks of unseasonably cool and unsettled weather over the eastern half of the Prairies, with near-average conditions over the west, it looks like more typically summer weather will move back in. The massive area of low pressure that spun […] Read more
