There are four main theories for how tornadoes are formed: The first two are tied together because they both involve super-cell thunderstorms. Thunderstorms are fuelled by warm, moist air near the surface and colder air aloft. What makes a super-cell thunderstorm different from a regular thunderstorm is the ability for the storm to sustain a […] Read more

Numbers confirm June colder, wetter than average
The number of days in June when daytime highs made it past 30 C show the unseasonal weather. Using only the main reporting stations from each province, Winnipeg was the only location to record a day above 30 C, when the daytime high hit 30.4 C on June 24. The warmest days in all other […] Read more
‘Weather market’ resumes role as price driver
The market is closely watching production problems around the world, including Russia, Europe, Argentina and the U.S.
GENEVA, Switzerland (Reuters) — Weather hiccups in major cereal producers have cast a doubt on prospects of a global grain glut and made fundamentals regain their status of key market drivers after being surpassed by politics, notably the war in Ukraine, analysts say. Wheat prices in Chicago gained 33 per cent in the past two […] Read more
Warmer winter projected for key U.S. crop areas, long range predictions less clear
SASKATOON — John Baranick’s crystal ball is cloudier than usual. DTN’s agricultural meteorologist has had trouble finding good analog years to help formulate his winter, spring and summer forecasts for 2024. “We don’t have a whole lot of history to guide us, and the models are kind of all over the place,” he told delegates […] Read more
Return of El Nino and a warmer ocean bring uncertainty
Weather extremes in recent months have so far had limited impact on global crop production but the prospects for the coming year are uncertain as the world faces the return of El Nino, coupled with exceptionally warm ocean temperatures. El Nino and La Nina are the two ends of the Pacific Ocean oscillation and we […] Read more
Storms hit China’s crops but too early to calculate damage
A typhoon and tropical storm have dumped enormous amounts of rain on northeastern China, creating damage that recalls crop-wrecking storms in 2020 that helped force the country to increase corn imports. China is assessing the damage caused in late July by Typhoon Doksuri and the heavy rain and flooding that followed. Another typhoon, called Khanun, […] Read more
‘Bad’ weather does not have to mean taking bad photos
The weather not only affects our crops and pastures, but our recreation and vacation time as well. We can make wonderful plans to go fishing, take a road trip or spend a day at the beach. But the weather often has other plans, serving up sudden storms, wind, hail, fog or this summer’s never-ending frustration […] Read more
July was cool in the east and warm in the west
July started off hot in Manitoba, but only the first two days had daytime highs above 30 C. After that, the province saw the development of a deep Hudson Bay upper low that meandered around for nearly two weeks, placing the eastern Prairies under a cool northerly flow. That weather pattern broke in the last […] Read more
Tornadoes can prove difficult to predict
How can you know if a storm is capable of producing severe weather? The answer is not easy. First, listen to Environment Canada for watches and warnings. It is the only entity allowed to issue watches and warnings in Canada. A watch means the potential exists for severe thunderstorms, but they have not yet developed […] Read more
July starts with troublesome upper-level low
Unless you are in a drought and praying for rain, upper-level lows are never a good thing. They are usually tough to forecast because they tend to move very slowly, and because of that, they can stick around for days or even weeks.
