Weak instability across southwestern Saskatchewan is expected to spark isolated, non-severe thunderstorms Wednesday afternoon and evening, with a risk of funnel clouds extending from Swift Current through Cabri, Leader, Fox Valley and the Eatonia area.
Environment Canada says showers lingering from a trough stalled over the western Prairies will gradually taper off during the day, but not before giving way to spotty thunderstorm development. While most storms are expected to remain weak, the potential for funnel clouds exists due to localized rotation under rapidly growing clouds.
These funnel clouds are usually harmless and short-lived, however, they can occasionally intensify into landspout tornadoes, which, while generally weak, may still cause minor damage.
Environment Canada says landspouts can topple trees, damage roofs and toss debris short distances. The agency is advising residents in the affected areas to take shelter if funnel clouds develop nearby and to remain alert, as these phenomena often form with little warning.
Meanwhile, further north, smoke and poor air quality continue to impact parts of northern Saskatchewan due to ongoing wildfire activity northeast of Prince Albert. Gusty afternoon winds have been fuelling fire intensity and smoke production, while overnight temperature inversions have been trapping smoke near the surface — leading to deteriorating air quality conditions after sunset.
Some light morning shower activity was noted in the fire zone, but it remains unclear whether the precipitation will significantly reduce fire behaviour later in the day.
Environment Canada says it will issue updated watches or warnings if conditions become more favourable for the development of landspout tornadoes.
Air quality alerts remain in place for parts of the north, with the public advised to limit outdoor activity if smoke becomes dense.
