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

It was a cold, dry winter no matter which way you look at it

The CFS model sees below-average temperatures on the southern Prairies in April

What can I say about the weather this March across the Prairies? “But it was a dry cold?” In this article we’ll look back at March’s consistently cold weather, but we’ll also look at how the meteorological winter (December to February) stacked up and how what I like to call “extended” winter — or, simply,


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

A bit of convectional wisdom

When solar energy becomes heat, the air rapidly begins to move around

At the time of this writing, there were just a few more days before being officially done with three types of winter seasons: It is almost time to look back at this past winter to see how it stacked up, but first let’s look at how energy is transferred around our little planet. This topic


Weather: Below average temperature trend continues

Forecast issued Mar. 24, 2023, covering the period from Mar. 29 to Apr. 5, 2023

Another week has come and gone, and the question remains: When will spring get here? Similar to last week’s forecast, the answer is, don’t hold your breath. It is going to slowly get warmer as the amount of daylight and strength of the Sun increases, but the overall weather pattern continues to lean toward continuation of below-average temperatures.

Reflecting on the Earth

Human influence is believed to be taking the shine off the planet

Before focusing on this issue’s meteorology 101 class, let’s look at February’s global temperatures. In the last article, I noted the current La Niña officially ended in February and we have now entered the neutral phase of ocean surface temperatures across the tropical Pacific. The La Niña phase is associated with cooler ocean temperatures that


Forecast: Arctic air continues to dominate

Issued March 17, 2023 • Covering the period from March 22 to 29, 2023

When will spring get here? When will the melt start? Those are the questions I’ve heard most in recent days. Thanks to a series of arctic highs, it looks like spring, or the melt, will not move in until early April. We saw the impact of these arctic highs in the last forecast period. For

Weather: Cold start, followed by slow warming trend

Forecast issued Mar. 10, 2023, covering the period from Mar. 15 to Mar. 22, 2023

If you follow the weather and weather forecasting, the last forecast period was interesting. If you have been following my weather articles and forecasts over the years, you know I rarely bash Environment Canada, but I couldn’t help but do a lot of head-scratching last week. Early last week it was forecasting several days of


Weather: Little if any snow expected

Forecast issued Mar. 3, 2023, covering the period from Mar. 8 to Mar. 15, 2023

You can tell when the weather pattern starts to switch into spring mode, not because we necessarily see warmer weather, but because the weather models have a tough time with medium-range forecasts. We saw this in the last forecast. Confidence was low and it looked as though we would be stuck between the two main

Seasonal math and atmospheric composition

When you fly by jet, more than 75 per cent of our atmosphere’s mass is below you

In the last article, we looked at the five reasons for the seasons. Sounds like it should be a song, doesn’t it? (“Time of the Season” by the Zombies always comes to mind — I know, I’m old.) To finish that discussion, let’s look at the “march of the seasons” and the extremes we encounter in day length
