The Storm Prediction Center confirmed five tornadoes touched down across three states over the past 48 hours, part of a broader severe weather outbreak that also produced 60 large hail reports and 255 damaging wind reports nationwide.
Confirmed tornado touchdowns were recorded near North Sterling Reservoir and Sterling, Colorado; near Andover and Pierpont, South Dakota; and near Flom, Minnesota, according to the Storm Prediction Center. Five active alerts remained tied to the event across Colorado, Minnesota and South Dakota as of Wednesday, per the National Weather Service.
The scale of the outbreak was driven less by the tornado count than by the sheer volume of accompanying severe weather. The 255 damaging wind reports and 60 large hail reports logged over the same 48-hour window indicate a widespread severe thunderstorm complex tracked across the central and northern Plains, with the tornadoes forming as the most destructive embedded threat within that system.
The National Weather Service notes that the immediate tornado threat from this system has passed, but warns that damage assessments are still underway in the affected communities. Residents in the Sterling, Colorado, area and in the Andover-Pierpont corridor of South Dakota should continue to follow guidance from local emergency management as crews inspect structures and clear debris. Downed trees, damaged roofing and power outages are common in the wake of confirmed tornado tracks, even when the storm itself has moved on.
Forecasters caution that this cluster of storms fits a broader early-summer pattern across the Plains and upper Midwest, where clashing air masses have repeatedly fueled severe thunderstorm development this season. With the parent system now exiting the region, the National Weather Service is monitoring for any redevelopment of severe storms later this week, though no new watches were tied to this event at last report.
For residents in and around the affected corridor, county-level weather offices remain the best source for real-time alerts as cleanup continues. Those in Colorado can also track local conditions via Denver weather, while residents farther north can check Minneapolis weather for updates on any lingering instability moving through the upper Midwest.
No additional tornadoes were reported beyond the five confirmed by the Storm Prediction Center, and the agency’s damage survey teams are expected to refine wind-speed and path-length estimates for each twister in the coming days.
