At storms move out this morning, more storms will redevelop this afternoon. As of right now, I’m thinking that storms will develop across central Nebraska, central South Dakota and possibly across northeast South Dakota and western Minnesota (along and north of US 212) later this afternoon. Here are some key time periods from our latest hour by hour forecast model:

Other than a very quick, isolated shower or thunderstorm this afternoon, I don’t expect storms in Sioux Falls until late tonight. Likely after midnight.

Storms could be severe. Hail and damaging straight-line wind gusts will be the primary threat, however, an isolated tornado or two is possible late this afternoon/evening with individual supercells that may develop. After sunset, storms will form into a line and the tornado threat will decrease. The main overnight threat will be hail and damaging straight line wind.

Here’s the severe risk map from the Storm Prediction Center as of 10am:

What happens this afternoon will be impacted by what happens by the storms that are out there this morning, so this could change a bit. I’ll be updating via twitter throughout the day.
