Nocturnal storm threat on the eastern Prairies will precede Thursday risk
A strong cluster of thunderstorms will persist overnight across the southern Prairies after tornado warnings were dropped, with another opportunity reappearing for active weather on Thursday for eastern parts of the region.
An active Wednesday on parts of the Prairies will continue into Thursday after a slew of tornado warnings were issued in the evening, with a group of storms continuing to push east.
While the tornado warnings have since been dropped, frequent lightning, heavy downpours and small hail will remain as nocturnal threats, in addition to wind gusts potentially reaching up to 90-100 km/h in southeastern Saskatchewan.
