Little change in the going forecast after the Storm Prediction Center updated its severe weather outlook for today. A slight risk remains in effect for the southern half of Iowa. The primary threat in Iowa tonight is thunderstorms producing strong, damaging winds as a frontal boundary moves into the state from the south and a low pressure system passes through just before sunset.
Tornadoes are also possible, but the greatest risk lies within supercells expected to develop south of Iowa this afternoon and evening. As a frontal boundary travels north towards Iowa, there could be a brief window of opportunity for tornadic development. Brief tornadoes are also possible along any bowing lines of thunderstorms that move through the state.
We’ll continue to follow the latest developments through this afternoon and bring you the latest. We’ll also plan on launching our live chat if needed tonight to provide information in real-time.
