A hot end to an overall cold spring

The CFS model favours above-average precipitation this summer

The start of June is the start of meteorological summer across the Northern Hemisphere. The meteorological seasons are each three months long. Summer is June to August, fall is September to November, winter is December to February, and spring is March to May. Astronomically, summer starts on the summer solstice, which falls on June 21. Now it’s time to look

In summer, it’s all about the thunderstorms

Meteorology 101: Certain ingredients are needed for a thunderstorm to be watch-worthy

It’s thunderstorm season, and though we haven’t reached that point in our weather school, let’s take a look at the topic. Summer has moved in, so weather discussion across the Prairies turn to one of two topics: drought or thunderstorms. It’s too early to talk about drought, but with heat and humidity moving back into


Understanding atmospheric circulation

METEOROLOGY 101 | Air in our region must contend with a messy interaction of land and water

The first thunderstorms have appeared in our region, so it’s time for our annual look at thunderstorms. But first, let’s continue our Meteorology 101 class to build on the base of knowledge needed to understand thunderstorms in more detail. In our last lesson, we looked at atmospheric circulation. On a simplified Earth, we would have thermally produced

Continuing our look at wind

Meteorology 101: There are reason why all of Earth’s air doesn’t flow north-south

In the last Meteorology 101 class, we introduced the four main forces that drive our winds: gravity, air pressure, Coriolis and friction. This week we will go into more detail to better understand what creates wind. Without gravity, there would be no weight to the atmosphere, and without weight there would be no air pressure.


Consistently cold April in Manitoba, Saskatchewan

The CFS model points to above-average temperatures and below-average precipitation

After a colder-than-average winter, followed by a colder-than-average start to spring, most of us across Manitoba were hoping April would break out of this cycle. It didn’t. Unless you spent every waking minute inside, it was just plain cold in April. Similar to March, we didn’t see record-breaking cold. It was just consistently cold. I’m

Weather: Warm temps finally return

Forecast issued Apr. 28, 2023, covering the period from May 3 to May 10, 2023

If you paid attention to the end of last week’s forecast, you might not be expecting a weather forecast in this issue. We are working to switch from print-based to web-based forecasting, which will allow us to create better and more timely forecasts. Well, you know the saying: best-laid plans. Due to unforeseen technical issues,


Weather: Cool and unsettled weather to continue

Forecast issued Apr. 21, 2023, covering the period from Apr. 26 to May 3, 2023

The last week’s forecast hit the nail on the head with respect to the overall weather pattern, as two different storm systems impacted our region as predicted. However, the models struggled with the interaction between these two systems. The first system hit southwestern regions on April 18 and 19. It then stalled out, while the

Weather: Winter tries to hang on

Forecast issued Apr. 14, 2023, covering the period from Apr. 19 to Apr. 26, 2023

Surprisingly for spring, last week’s forecast played out close to what the weather models predicted. The expected Colorado low late in the week developed as the models thought it would. It moved in earlier and moved out earlier and was not as strong as forecasted. It did intensify, but not until it was in northern Ontario, and that


Weather: Melting temperatures but more precipitation?

Forecast issued Apr. 6, 2023, covering the period from Apr. 12 to Apr. 19, 2023

Every time there is a Colorado low in the forecast, I note that we need to keep an eye on them. Last week’s Colorado low was a classic example. Initially it looked like it would stay to our south, but shortly after I sent the forecast, the weather models began inching it northward. Unless you

Weather: Below-average temperatures to continue

Forecast issued Mar. 31, 2023, covering the period from Apr. 5 to Apr. 12, 2023

Last week’s forecast played out surprisingly well. The storm system predicted to slide to our south at the start of the forecast period developed as expected but tracked further south than originally forecast, thanks to — you guessed it — strong arctic high pressure over our region. The quick weekend storm system looks to be
