When a line of strong thunderstorms swept through eastern South Dakota Tuesday night, meteorologists weren’t surprised. The National Storm Prediction Center had placed the region under an advanced risk for severe weather, after all. But then a suspected tornado spun up on the leading edge of the storm – surprising even veteran weather watchers. The winds whipped through the south side of the city, damaging 37 structures – including a hospital – and leaving several thousands without power.

MPR News with Kerri Miller spoke with meteorologist Sam Gabrielli, from ABC affiliate KSFY in Sioux Falls, about the unusual aspects of the storm, and how the public can better prepare for severe weather that happens when most people are sleeping.
