This map shows the total amount of precipitation that has fallen across the Prairies so far this growing season compared to historical values. It continues to be a dry start to the growing season across nearly 
all of Manitoba and much of Saskatchewan, with wide areas reporting values that are very low to extremely low. 


Diving a little deeper into summer weather and tornadoes

Tornadoes are nearly impossible to study but we do know a lot 
about the mechanics of how they form

In this instalment, we’ll continue our look at severe thunderstorms, and specifically, the most deadly part — tornadoes. While eastern parts of the Prairies have only seen a few isolated severe thunderstorms, parts of Saskatchewan and Alberta have already seen their fair share. I think most Canadians were more than impressed, and maybe a little bit […] Read more

This map shows the amount of precipitation compared to average that fell across the Prairies over the 30-day period ending on May 25. It continues to be a tale of east versus west, with most of Alberta reporting average to above-average amounts, while in Manitoba amounts have been well below average. In Saskatchewan, southern and eastern regions have been dry while northern sections have been wet.

Tornado season is upon us — here’s what to watch for

The area between the storm and cloud, clouds with bags hanging from them, and the wind are keys in spotting the danger

So far in our look at severe summer weather, and in particular thunderstorms, we have looked at how thunderstorms form, how they can grow into severe thunderstorms, and finally, how hail is produced. Next up on the severe thunderstorm list is tornadoes! Before we begin our look at tornadoes though, I think we have to […] Read more


This map shows the total amount of precipitation that fell across the Prairies compared to average during the 30-day period ending on June 9. It is evident that this has been a fairly active period, with a large portion of all three Prairie provinces showing near- to above-average amounts of rainfall. The wettest regions were found in Alberta, stretching from Grande Prairie southeastwards towards Coronation and western Saskatchewan and southeastern Saskatchewan to southwestern Manitoba. Interestingly, north-central Saskatchewan was very dry during this period.

It’s that time of year when severe summer weather and tornadoes can form

Tornadoes have occurred in nearly all regions of Canada — 
here is what to look for when a severe storm is approaching

As we enter the peak season for severe weather across the Canadian Prairies, I figured now would be a good time to continue our look at severe weather and tornadoes. While Alberta doesn’t see the same number of tornadoes relative to areas to the east and south, the province is still subject to these events. Before […] Read more

This map shows the total amount of precipitation that fell across Alberta during 2015, well almost. It covers the 365-day period ending on Dec. 15. 
You can see that overall, it was a fairly dry year, with parts of the southern, northern, and Peace River regions experiencing one-in-12-year to greater than one-in-50-year dryness. The wettest areas (green) only saw near-average amounts.

When Mother Nature goes to extremes, the consequences are massive

Whether it’s heat or cold, dry or wet, you can only hope 
these records will stand for a long, long time

Each year Environment Canada puts out its Top 10 weather stories and I like to go through them taking a more western focus. I thought it might be interesting to go back over the last 115 years or so and look at some of the biggest weather stories to hit the Canadian Prairies — according […] Read more


Severe summer weather. Taking a look at thunderstorms and wind

Everyone knows what a funnel cloud looks like, but understanding how it forms isn’t easy

In continuing our look at severe thunderstorms, we’ll look at specifically, the most deadly part — tornadoes. What are tornadoes and how do they form? A classic definition of a tornado is a violently rotating column of air that extends from a thunderstorm to the ground, which may or may not be visible as a funnel cloud. For […] Read more

Three-hour tornado & Regina’s wettest day ever

Reuters — A tornado spun for several hours through southwestern Manitoba late Monday in a fierce Canadian Prairie storm that caused flash flooding and shredded part of a highway. No injuries or major damage was reported, according to a statement by Environment Canada, federal weather forecaster. “What was just shocking was the duration on the […] Read more
