Back to thunderstorm school — lesson two

Thunderstorms are often associated with a hot day, but that’s not the only ingredient required for them to form

It seems that Mother Nature is letting winter have one last hurrah, but that doesn’t mean that thunderstorm season is too far off. So for this issue we’ll continue our annual look at what is arguably one of the most fascinating weather phenomena we see in our part of the world. I always like to

El Niño conditions are developing in the Pacific

We know La Niña and El Niño both have an effect on weather — but predicting it is still a real challenge

El Niño conditions are developing across the Pacific with an increasing probability that a full-fledged El Niño episode will occur during the second half of 2017. Pacific equatorial winds have slackened since the start of the year and a characteristic tongue of warm water has begun to form stretching from Peru towards the international dateline.


Forecast: Pleasant spring weather ahead

Issued May 8, 2017 – Covering the period from May 10 to May 17, 2017

Last week’s forecast didn’t turn out exactly as predicted, but it wasn’t due to a lack of trying by Mother Nature. The broad area of low pressure formed to our west as predicted and we did see some low to even mid-20s for highs late last week. Then a weak cold front moved through our

Weather cooperates, drying fields, improving seeding progress

Manitoba Crop Report and Crop Weather report for May 8, 2017

Manitoba Agriculture – Warm, dry and windy weather conditions prevailed across the province allowing for favourable drying of soil surface. More and more fields are accessible for field work and seeding operations to progress. Planting of cereal grains advanced the most. Field peas, canola and corn are also being planted. Many areas continue to report soil


Weed-Bane herbicide, ‘harmless to humans’

Weed-Bane herbicide, ‘harmless to humans’

Our History: May 1948

Naugatuck Weed-Bane advertised in our May 6, 1948 issue was said to be a 2,4-D formulation developed specifically for Canada’s colder climate, and harmless to grass, soil, animals and humans. We reported that flooding was causing serious damage along the Red and Assiniboine rivers, and that many homes had been flooded on low river land

Forecast: Warm weather returning with a vengeance?

Issued May 1, 2017 – Covering the period from May 3 to May 10, 2017

Last week’s storm system was a bust, as it slid farther east than expected and therefore, for the most part, only impacted the extreme southeastern portion of our province. The wraparound cloud did keep areas east of the Red River Valley on the cloudy side until last Friday, while western regions received mostly sunshine. By



Seeding underway in many parts of Manitoba

Manitoba Crop Report and Crop Weather report for May 1, 2017

Manitoba Agriculture – Favourable weather and field conditions have allowed seeding operations to get underway in many areas of Manitoba. Provincially, it is estimated that less than five per cent of the 2017 crop has been seeded. No meaningful precipitation received during the past week and soil surface conditions are drying nicely across the province.


Severe versus air mass thunderstorms

Storms that don’t rotate or have any way to vent rising air rarely last long

A couple of weeks ago we talked about what it takes to form severe thunderstorms: heat, humidity, lift, and some way to vent the air at the top of the storm. This week we’ll take a look at what it takes to make a severe thunderstorm and turn it into a thunderstorm that you just

Forecast: Very slow return towards warmer weather

Issued April 24, 2017 – Covering the period from April 26 to May 3, 2017

Once again it seems that the writing of my forecast coincides with a possible major storm system. I write my forecasts late on Sunday or early on Monday and you see it Wednesday. For this forecast period, whether some regions saw significant snowfall on Monday will have an impact on temperatures until at least Friday.
