Forecast: Colder-than-average temperatures ahead

Covering the period from October 28 to November 4

The first part of the last issue’s forecast turned out pretty good, as the strong northwesterly flow established itself dropping temperatures into the bottom end of the usual temperature range for this time of the year. The models were holding firm about a big warm-up by the end of the month, but now it is looking like that warm-up will be not

Rossby waves in the northern hemisphere. At any given time, there will typically be between four and six Rossby waves at different stages of development in the Northern Hemisphere.

Weather school: Globs of cold air and Rossby waves

The Weather Network expects a cold December, at least in our neighbour states

In the last issue we started to examine why our part of the world has such changeable weather. We looked at general global circulation patterns, then examined the zone where westerly winds bump up against easterly moving polar winds, creating giant eddies of swirling air. This week we are going to continue our look at these swirling eddies


Whether you spread out bales or group them in ‘pods,’ don’t worry about the residue left behind — it isn’t wasted.

Bale grazing is having its moment in the (winter) sun

Here are some things to bear in mind when using bales to extend the grazing season

Many producers have taken steps to extend their grazing period, and bale grazing is proving to be a popular choice. Bales can be purchased or grown on farm and placed strategically in cells or ‘bale pods.’ In some cases, cattle feed on bales directly where they are dropped from the baler, but in most situations, bales

Potato producers have been spared sights like this in 2020, although yields may have fallen short of what many producers would have liked.

Smooth harvest, but short yield for potato growers

Manitoba won’t see the undug acres of 2018 and 2019, although many yields aren’t bursting any storages

Manitoba’s potato crop won’t be breaking yield records. Then again, at least the crop is off the field. It has not been the case for the last two years. Producers were forced to abandon a significant portion of their crop in both 2018 and 2019 due to wet falls and damage from frost. Last year,

Forecast: Cold with slight chance of snow

Once again, the weather models did a pretty good job with the medium-range forecast. The northern Manitoba low stalled out as forecast, and we saw the resulting surge of cold air push southward, bringing an abrupt end to the seasonable fall temperatures. The only thing the weather models got wrong was that the daytime highs ended up being a little cooler



La Nina winters have a slightly higher-than-average chance of being cooler and wetter than average.

Canada’s CanSIPS model still calls for a warmer-than-average October

Icannot believe another month has come and gone. Sometimes it seems like it was the longest month ever and other times it felt like one of the fastest. September’s weather kind of mirrored my feelings. Sometimes it seemed like fall was here to stay and at other times summer tried to make a comeback. The question is whether

Forecast: Let’s ride the temperature rollercoaster

Well, we definitely saw the cold northwesterly flow develop last week that allowed cool arctic air to drop southeastward, bringing the first good blast of fall weather. At least we did not see any snow, or at least I did not hear about any. The weather models did a good job calling for that cooldown,


Weather conditions during field drying, after plants are frozen, impact the colour of the harvested soybeans.

Management tips for frost-damaged soybeans

Soybeans killed at growth stages of full seed development and beginning maturity should be left out in the field to dry before harvest

An early frost has producers wondering what to do with immature frost-damaged soybeans. “Soybeans killed at growth stages of full seed development (R6) and beginning maturity (R7) should be left out in the field to dry and harvested along with mature soybeans (R8) when the beans are at the desired moisture content,” advises Ken Hellevang,

The province says about 44 per cent of Manitoba’s nitrogen application is done in fall.

Shadows of 2019 has producers itchy on fall nitrogen

Producers don’t want a repeat of last fall, when poor conditions shut many producers out of their normal autumn application

Producers may be chomping at the bit to get fall nitrogen on, given conditions last year, but those same producers are taking a risk on nitrogen loss should the weather turn unfriendly. John Heard, crop nutrition specialist with Manitoba Agriculture and Resource Development, warned producers to be wary of warm soils if they’re gambling on early application. Why
