Forecast: Winter doesn’t want to leave

Covering the period from April 1 to April 8

If I’ve said it once, I have said it at least a hundred times: Forecasting the weather at this time of the year is hard. If you have been following the weather models over the last couple of weeks you would know what I mean. One day they forecast a big warm-up and next a

If Earthshine increases, then Earth is reflecting more of the sun’s energy and as a result, the Earth should cool, and vice versa.

Longer-range spring weather forecasts aren’t all in lockstep just yet

With COVID-19 forcing students to take a break from going to school, it doesn’t mean that they’re not supposed to still do schoolwork — so while I’m prepping online material for my students, I think it’s only fair we continue with my online weather course. This issue we’re going to continue our look at the

Forecast: Spring weather slow to move in

Covering the period from March 25 to April 1

Well, my last forecast was not too bad — a little optimistic on temperatures, maybe, but the overall pattern was handled pretty well by the weather models. The main reason is that we seem to be stuck in this particular weather pattern, so until something big comes along to change it, expect more of the

At sunrise and sunset, the angle of the sun is such that the insolation has to travel through much more atmosphere than during the day.

Insolation is the driving force behind all our weather

After taking a bit of a break from Weather School, it’s time to get right back at it. With all the craziness going on in the world, hopefully a little bit of learning from the comfort of home or the office is just what you need. Plus, with really mild spring weather still a couple

Forecast: Colder-than-average temperatures expected

Covering the period from March 18 to March 25

For those of you who regularly read my forecasts, you will know I hate to write forecasts in the spring and fall — but especially in the spring. The yearly fight between cold and warm air in the spring often makes it difficult to accurately predict the weather beyond about five days. Since I write

Weather school: Breaking down the atmosphere

If you fly up to about 5,000 m, nearly half the atmosphere’s mass is below you

After taking a week off from Weather School to take our monthly look back at the previous month’s weather, and to peer ahead to see what type of weather we may see over the next couple of months, it’s time to finish up our discussion about the seasons. We need to take a look at

Forecast: One final shot of arctic air ahead?

Covering the period from March 11 to March 18

As expected, we did see an active storm track during the last forecast period, and as often happens, the weather models struggled. The biggest issue the weather models seem to have is with the intensity of the cold air. The models keep trying to drop in some fairly cold air, but so far, we have

Temperatures for February 2020 were right around average for the Dauphin, Brandon and Winnipeg reporting regions.

This February was much warmer than the last

The CanSIPS model predicts a colder-than-average March for the Prairies

You guessed it, it’s that time again, to look back at the previous month’s weather, then look ahead to see what the next couple of months might have in store. At this time of year, with spring just around the corner, the long-range forecast takes on a little more importance. Let’s begin by looking back

Forecast: Storm track setting up to our north

Covering the period from March 4 to March 11

Last issue’s forecast did an OK job. It captured the overall pattern, but was a little off regarding temperatures and overpredicted the amount of snow with a weak area of low pressure. This forecast period looks like it will be an interesting one. Weather models show the main storm track setting up across the central

Weather school: Five reasons for the seasons

Earth is a spinning top tilted to one side – and is always tilted in the same direction

In our previous Weather School class we looked at incoming solar radiation and the solar constant. With no new or exciting happenings in our local weather, we’re going to continue our look at how the incoming energy from the sun drives the seasons and weather we experience here on Earth. Net global radiation is the
