Unseasonably cool weather has dominated the southern Prairies this June, with below-average daytime highs and a series of severe thunderstorms. The persistent upper low pressure systems from the Pacific have contributed to these conditions, keeping temperatures cooler, especially in Alberta. Saskatoon has recorded daytime highs that have not exceeded 30°C this month, with a maximum of only 26.9°C, marking the first June without such a high temperature since 2024. This weekend, another low-pressure system is set to bring heavy rain and severe thunderstorms, particularly impacting south and central Saskatchewan and southwestern Manitoba, with risks of strong winds, hail, and significant rainfall accumulation. Tornado activity has also increased, with seven confirmed tornadoes reported in Saskatchewan this year, including a notable EF-3 tornado in Oxbow earlier this month.
Why It Matters
Severe weather patterns have a significant impact on agriculture, infrastructure, and public safety in the Prairies. Tornadoes, while a natural occurrence, can lead to damage and pose risks to residents, as evidenced by the EF-3 tornado that recently struck Saskatchewan, marking the province’s strongest tornado in over a decade. Historically, Saskatchewan averages 14 to 15 tornadoes annually, and the early onset of severe weather this year may indicate heightened activity. With climate patterns shifting, understanding these weather phenomena is crucial for preparedness and response efforts within affected communities.
