This map shows the total amount of precipitation that has fallen across the Prairies so far this growing season (April 1 to Aug. 27). You can see just how dry it has been this year across the southern and central Prairies. A large part of this region has seen less than 250 millimetres over this five-month period, with large parts of Saskatchewan and southwestern Alberta seeing less than 200 millimetres. The only ‘wet’ area is in northwestern Saskatchewan and 
north-central Alberta where precipitation amounts are in the 400- to 500-millimetre range.

There are extreme rains, and then the deluge caused by Harvey

Some parts of Texas received more rain in 24 hours than 
Prairie centres have seen in their wettest-ever month

As fairly quiet weather continues across the Prairies, the big weather story recently has been Hurricane Harvey, which came ashore in Texas late on Aug. 26. Harvey rapidly strengthened in the 12-hour period leading up to landfall and came ashore as a borderline Category 4 hurricane, with top winds of 210 kilometres per hour. It wasn’t […] Read more

Watch for nitrate accumulation after a hailstorm

Water and nutrients, including nitrogen, are pushed into non-legume crops after hail damage

There are many things to consider when salvaging a damaged cereal, oilseed, or hay crop after a hail event. One of them is nitrate accumulation, which occurs in a plant when it is injured and unable to convert nitrate to protein efficiently after a hailstorm. In non-legume crops, water and nutrients are pushed into the […] Read more

Storms trim potential for big Prairie crops

Reuters — Heavy rain and strong winds are likely to curb the potential for Western Canada’s crops, government officials said, but the harvest may still be bigger than average. Pockets across Saskatchewan, Canada’s biggest wheat- and canola-growing province, received as much as five inches of rain, strong winds and hail since Sunday. The storms flattened […] Read more

This map shows September’s global temperatures as percentiles ranging from record cold to record warmth. It’s easy to see just why it was one of, if not the, warmest September on record. With the exception of a few small areas of cooler to much cooler-than-average temperatures, most of the planet saw warmer to much warmer-than-average temperatures, with large areas seeing record warmth.

The latest winter outlook and more on cold weather precipitation

October was a pleasant change from September, but will the 
warmer-than-average weather continue for the rest of the year?

In my last article I said that we’d continue our discussion on cold weather precipitation. But before diving into that icy topic, I want to take a look at the weather so far this fall and see if the long-range winter forecasts have changed. After experiencing a cooler- and wetter-than-average September across pretty much all of agricultural […] Read more

Severe summer weather. Taking a look at thunderstorms and wind

Everyone knows what a funnel cloud looks like, but understanding how it forms isn’t easy

In continuing our look at severe thunderstorms, we’ll look at specifically, the most deadly part — tornadoes. What are tornadoes and how do they form? A classic definition of a tornado is a violently rotating column of air that extends from a thunderstorm to the ground, which may or may not be visible as a funnel cloud. For […] Read more

Keep watch: How to spot the warning signs of a tornado

A dark area between the storm and the ground, a green tint to the sky, and a line of swirling clouds are all danger signs

This next topic in our look at different types of severe summer weather is severe thunderstorms, and in particular, high winds. When we think of severe thunderstorms one word that should make you worried and nervous is tornado. While tornadoes are the most destructive feature that can occur within a thunderstorm, they are fairly rare, with […] Read more

When it comes to hail, not all parts of the Prairies are equal

South-central Alberta and south-central Manitoba get the worst hailstorms — but for different reasons

So far in our look at different types of severe summer weather, we’ve looked at heavy rainfall warnings and heat warnings. I was going to take a break from our examination of severe summer weather for this issue and examine some of the unique weather events that have taken place across the world over the […] Read more
