Getting a sense of snowfall probabilities

A big storm with more than 30 cm of snow is a once-in-10-years kind of event

The number of recent weather questions has dropped to nothing. Maybe we have answered all the weather questions! Whenever this happens and nothing major has occurred weather-wise in our neck of the woods, I like to look back at some of my weather articles from the last 19 years. That’s right, by the end of

Understanding Alberta clippers and Colorado lows

The Rockies and the troposphere help set up peculiar curves

Last spring and a few times this fall, the Prairies have seen several large winter storm systems. Most big fall or winter snowfalls come from areas of low pressure that develop to the lee of the Rocky Mountains. One area of development is over Alberta, producing what’s affectionately referred to as an Alberta clipper. The


Weather: Northwesterly flow expected to develop

Forecast issued November 11, covering the period from November 16 to 23, 2022

Weather models had a good handle on our last forecast period. They were correct about the development and overall movement of last week’s Colorado low. It developed as forecasted and ended up moving northeast in two waves, as expected. The first wave was early in the week; the second, late in the week. Timing of

Weather: Chance of stormy weather but lots of uncertainty

Forecast issued November 4, covering the period from November 9 to 16, 2022

What is the old saying? Don’t like the weather? Wait a minute. That seems totally appropriate for our current weather pattern.  We are in a very active pattern as the persistent ridge of high pressure that brought warm fall weather across Western Canada has collapsed and, in its place, we have a large trough of


Lots of disagreement on early winter weather predictions

Depending on what model you’re looking at, it’s anyone’s guess this winter

I keep promising to take a final look at this year’s frost data, but here we are at the end of another month. Though there are a couple days left in October as I write this, by the time you read it we will already be a couple of days into November. If I wait



Weather: Looking for the start of winter

Forecast issued October 28, covering the period from November 2 to November 9, 2022

Last issue’s forecast turned out not too badly, with only a couple of wrinkles. There was a faster than expected return to mild temperatures and instead of a southern low, the western ridge rebounded, bringing nice warm fall weather through the last weekend of October. As we head into November, we will see average daytime

The science behind snow fences

Consider your land’s natural snow trapping capacity before laying out a fence

At the end of the last article, I said we would look at the frost-free season this past year, but I received a couple of emails asking if I could revisit the topic of snow fences. It has been a long time since we touched on this topic. With this in mind, and with winter


Fall frost and the frost-free season

For most spots in agro-Manitoba, a frost in early September wouldn’t be all that unusual

I am a little reluctant to write about fall frost this year because I have been given a little flak over the last few months about how, every time I write about something, it seems to happen. What can I say, other than “I wish I had that kind of power over the weather!” When

Not all weather folklore consistently pans out

SAYINGS | Prevailing weather adages usually cover the short-term outlook, and for good reason

Over the last month or so I have crisscrossed this great country of ours. I started in early July heading east into the Muskoka region of Ontario to compete in an Ironman 70.3 triathlon. After spending a couple of weeks there, I returned home and did some quick gardening before heading west to Canmore, Alta.
