Environment and Climate Change Canada issued tornado warnings late Thursday for parts of southeastern Saskatchewan and neighboring southwestern Manitoba as a line of supercell thunderstorms tracked across the provincial border on 3–4 July. The alerts covered the Rural Municipality of Antler, including the communities of Redvers, Antler and Wauchope, after storm spotters reported rotating wall clouds and textbook supercell structure shortly before 5 p.m. local time. Additional warnings were later posted for extreme eastern Saskatchewan when a second storm intensified. Chasers observing the system from Heward, Stoughton and other nearby towns documented multiple wall clouds, rapid rotation and a storm-merger near the Manitoba border. By about 8:30 p.m. CDT, the primary cell had crossed into Manitoba, producing dramatic cloud formations but weakening rotation. No confirmed tornado touchdowns, injuries or significant damage had been reported as of late Thursday night, but authorities advised residents to remain prepared for rapidly changing conditions as the storms continued eastward.
