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

One might suspect the wilted sunflower seeding on the right was damaged by frost May 30, but Anastasia Kubinec, Manitoba Agriculture and Resource Development's (MARD) manager of crop industry development, says a cutworm was the culprit. She says farmers should be checking their fields for more than frost damage right now.

Frost was mostly light, but check your fields for other crop stressors right now

Flea beetles and cutworms are on the rise, while packed soils and dry hot winds are other things to watch for

[UPDATED: June 2, 2020] Potential frost damage might be the least of the many crop stressors Manitoba farmers see as they scout their fields the next several days. “Frost is just one of the factors we’re looking for right now,” Anastasia Kubinec, Manitoba Agriculture and Resource Development’s (MARD) Manager of Crop Industry Development, said in


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


Fair weather sees seeded cereal, canola crops quickly emerge

Manitoba Crop Report and Crop Weather report for May 26

Southwest Region Most of the southwest region received rainfall during past week and on the weekend. Thundershowers in some areas brought a significant rainfall in short period of time. Amounts are varied and can be viewed here. Some areas close to Boissevain and southeast parts of the region toward Killarney, already dealing with surplus moisture,

Forecast: Summer weather tries to move in

Covering the period from May 20 to May 27

There was a little discrepancy in last week’s weather outlook. We had more clouds and showers early on, before the predicted milder air finally moved in over the long weekend. The strong area of low pressure predicted to begin affecting our region May 18 to 20 is still on track as I’m writing this, but


If a usually cold region of the Earth’s north is experiencing very warm temperatures, such as the midsummer heat Churchill saw late last month, then some other region, such as southern Manitoba, is seeing a colder spell.

Anything flowing over the Earth deflects off a straight path due to the planet’s rotation

Before forcing our way into our next weather school topic, here is a quick look at global temperatures for April. As we all know, April across central North America was not warm, but globally it was another very warm month. According to the Copernicus Climate Change Service, this April came in tied with April 2016

Ellis Seeds burns an unharvested flax field near Wawanesa this spring after quality samples deemed it not worth harvesting.

Cold spring keeps a tight leash on seeding

Farmers are bemoaning the late start to seeding, on top of the issues carried over from last fall

Farmers across Manitoba were ready to hit the field by early May, but Mother Nature wasn’t co-operating. Cold temperatures delayed seeding across the province through the first part of May. According to the first Manitoba crop report May 5, producers had only managed a “piecemeal approach” to seeding at that point. Why it matters: Farmers


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.

Pulse, cereal crops see seeding progress across Manitoba

Manitoba Crop Report and Crop Weather report for May 12

Southwest Region Cool and wet conditions were the norm last week. Moderate snowfall happened across much of the region, stalling all field activities for two days. Total precipitation was 2 to 10 mm in different areas. Snow melted quickly and producers were able to start some seeding again. Very cold overnight temperatures coupled with below
