Forecast: Cool weather and an unsettled start

Covering the period from June 10 to June 17

The weather models did a fairly decent job with last article’s general weather outlook. I am hoping, for this outlook — at least for the first half — that the models are off, as it looks like a cool and wet start. There is a little bit of uncertainty with the early part of this forecast, as it’s quite

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

Weather school: What creates a thunderstorm?

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: Warm weather with increasing humidity

Covering the period from May 27 to June 3

The main area of low pressure that the models forecasted to impact our region during the last forecast period did materialize, but it ended up taking a much more westerly route than expected. In fact, the low retrograded or moved from east to west a little bit. This meant the rainfall from this system fell

Regions of high pressure and low pressure, by latitude and altitude.

Weather school: General atmospheric circulation

Our planet’s rotation sets up a much more complex pattern of worldwide winds

Before wrapping up our weather school look at winds and working our way into general atmospheric circulation, I figured I should try to give a quick explanation of what has been driving our recent bout of cold weather. The jet stream — a narrow band of rapidly flowing air in the upper atmosphere, which usually


This weather graphic comes to us from the European Union’s Copernicus Climate Change Service and shows the global surface air temperature anomalies for April 2020. April was very warm across a large part of Siberia as well as Greenland. It also jumps out that much of central North America was colder than average, with the coldest region found just to our west and northwest.

Forecast: Milder with a chance of rain

Covering the period from May 13 to May 20

Last week’s weather outlook turned out to be remarkably accurate — way to go, weather models! The only piece that was slightly off was the Alberta low that was forecast to affect southern Manitoba last weekend and into the first part of this week. That low moved in a little quicker and mostly tracked through southern Saskatchewan. Now, on to this week’s outlook. Good news! I am

A return to cooler weather in May?

The CanSIPS model expects near- to above-average precipitation in May

Idon’t know about you, but being stuck at home working for a whole month actually made the month go by faster; seriously, it’s already May! That means it’s time for our look back at last month’s weather and our look ahead to see what the weather prognosticators say for the rest of May and June.


Forecast: Cool with a chance of rain, even snow

Covering the period from May 6 to May 13

Well, as it is starting to look and feel a little more like spring out there, I wish the latest forecast was as rosy looking as the last. During the last forecast period we saw warm air work in as expected, and several areas saw their first 20 C day of the year. The strong

Wind is one of the constant aspects of weather affecting just about everyone on Earth no matter where 
they live. 

Weather school: Gravity + pressure + Coriolis + friction = wind

Even within weather systems, there’s no getting away from the force of friction

As most students are struggling coming to terms with learning online, you readers are becoming experts. Last week in weather school we discussed the heating difference between land and water and were tying that into the overall energy balance of our planet. This energy balance, or rather, lack of balance, is what drives pretty much


If you thought the weather earlier this month in Manitoba was for the birds, well, you might be on to something.

Weather outlook points to a cool, wet spring

Manitoba’s March 2020 was warmer than average, albeit not by much

What’s the old saying: in like a lion, out like a lamb? Don’t you just love April? In most of our minds, once April rolls around it is supposed to turn nice and warm and our thoughts turn to planting. What we tend to forget is that April — especially the first two weeks of

Forecast: More sun than clouds, but cool

Covering the period from April 8 to April 15

If you recall last week’s forecast, I didn’t have a lot of confidence in the weather models, but as it turned out, they did a fairly good job. The one thing they missed out on was the intensity of the snow with the storm system that brought a widespread 10 to 20 cm of snow
