Wind gusts clocked in at more than 130 kilometres per hour in Weyburn as the storm kicked up Friday night.
Powerful gusts of 115 kilometres per hour were also recorded in Leader and Regina.
The winds snapped large trees, sending them crashing onto homes and power lines.
At one point, 11,500 people were without power in Regina alone. Outages stretched across the south of the province, with some customers waiting in the dark into Saturday afternoon.
Regina's water treatment plant was among the buildings that lost power. Ken Wiens, manager of the water operations branch at the City of Regina, said power was restored on Saturday, but repair crews then discovered a transformer had failed.
Until the transformer is fully repaired, Regina residents are being asked to limit their water use.
“We’re asking our customers to avoid any discretionary water use –- watering of lawns and gardens, washing of cars, that sort of thing,” Wiens said.
The storm didn't bring any substantial rainfall to the area, but 2-centimetre hail was reported in some communities.
More severe storms rumbled through central Saskatchewan on Sunday night.
One person was injured when a storm ripped through the Poplar Point campground near Big River.
Firefighters worked quickly to clear debris from the area so first responders could check on campers. Everyone was accounted for.
