Warmer and wetter future for Prairie farms

Higher humidity and intense rainfall events are all but inevitable as the planet warms

Warming oceans and warming air translate to more humidity. For Manitoba farmers, greater availability of water vapour will make it more likely for precipitation events to tend to the extreme.




Why rain turns into raining cats and dogs

What causes heavy rainfall on the Prairies?

Several factors can contribute to heavy rainfall events

Several factors must come together for an extreme rainfall event to occur. Sometimes you need more than one factor and other times, if the factor is strong enough, you just need one.

Despite all the available knowledge and technology, we’re not entirely sure why they occur

Despite all the available knowledge and technology, we're not entirely sure why tornadoes happen, but here are our best guesses.

Thunderstorms and heavy rainfall

Warm-season storm systems can have a lot of water to work with

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. With the storm system that brought heavy


The more water vapour there is in the air, the more potential energy exists to help a 
thunderstorm develop.

A large difference in temperature between two areas is needed for a storm to form

It’s thunderstorm season, and while we haven’t seen any big storms so far this year, the heat seems to have moved in, so it is only a matter of time! We are going to begin with the same issue I bring up every year, which is how people mix up weather watches and weather warnings. Basically, when we

Forecast: More showers, then sunny and dry

Forecast issued Monday, July 15, 2019 covering July 17-24, 2019

Once again, the weather models did a pretty good job with the forecast.

This forecast period will begin fairly unsettled as a broad area of low pressure tracks

Continuing with severe summer weather: Tornadoes

The peak tornado months within Canada’s tornado season are approaching

I know in the May 23 issue I said we would take a break from our annual look at severe weather and take a look back at the spring of 2019, then see what the latest long-range forecasts say. It appears I was a little ahead of myself as there are still five days left

You don't necessarily need a really tall thunderstorm to get the really big hailstones

Time to continue our series of articles on different types of severe summer weather. I like to re-examine these topics every year or two due to the importance of understanding the different types of severe weather, and also because most people find this aspect of weather so fascinating. In this issue we are going to
