Severe versus air mass thunderstorms

So far in our look at severe thunderstorms we’ve looked at the three main severe weather threats: heavy rain, hail, and wind or tornadoes. What we haven’t discussed or looked at is why do some thunderstorms become severe while others do not, and how can you tell if a thunderstorm moving towards you is going

Weekly weather forecast for July 15, 2013

The only thing that prevented us from climbing into the low 30s last week was the extra cloud sticking around, along with the fairly high humidities. For this forecast period it looks like summer wants to stick around. The ridge of high pressure that has been periodically building and weakening over the western U.S. is

Professional storm chasers follow wild Prairie weather

Manitobans battered by severe summer storms aren’t the only ones watching to see what the heavens deliver next — storm chasers are also keeping a close eye on the province’s wild weather. “Storm chasing is not nearly as prevalent as it is down here, but there are more and more storm chasers in the Canadian



Expect more heavy summer rainfalls

When we think about severe summer weather we almost always think of damaging winds and hail. While these two features can result in severe damage, the kind of damage is often highly localized. One thing about severe summer weather that we tend not to think about, until it creeps up on us, is heavy or

Dry, hot weather expected

Weekly weather forecast

The biggest problem with last week’s forecast was that the low pressure system expected to zip through the region over the weekend ended up moving much slower. This allowed for several rounds of rain to form and rotate through our region, bringing too much rain to some areas and some much-needed rain to others. This


Get used to it?

Just as water and climate expert Bob Sandford began his keynote address at a Winnipeg conference about water management last week, he received a text from his son back home in Canmore, Alta. It was about a river gone wild. As Sandford spoke on the science of why weather patterns are becoming more turbulent, resulting

Take steps to adapt to climate change: Vilsack

Excerpt from a speech by U.S. Agriculture Secretary Tom Vilsack to the National Press Club in Washington, June 5, 2013. I’m the secretary of agriculture, and I am not here today to give a scientific lecture on climate change. I’m here to tell you what we’re seeing on the ground. We’re seeing more severe storms.


Big storms should stay away this week

While the weather across our region was relatively quiet last week, the weather pattern as a whole was not behaving quite like I predicted it would. Last week I pointed out that we were now into a summer pattern with weaker weather systems and more thunderstorms. We definitely saw more thunderstorms last week, along with

The ingredients of a tornado

After a fairly cool spring with few if any thunderstorms, summer has started to make headway into the Prairies over the last few weeks. In some years summers come and go with only the odd thundershower and maybe one big thunderstorm, but in other years every storm that comes along seems to bring severe weather.
