CEDAR RAPIDS, Iowa (KCRG-TV9) - Thunderstorms are expected to develop in southern Minnesota or northern Iowa Saturday evening, then move southeast across eastern Iowa. The main timing is somewhere between 5 p.m. and midnight although it could be later depending on when and where the storms form.
The main severe weather threat will be strong winds. A few tornadoes and large hail are also possible. Locally heavy rain will also be possible. The area most at risk of flash flooding is northern Iowa where the ground is still saturated from Friday's soaking rain.
If you're at an outdoor event late Saturday, stay weather aware. Lightning is a danger if you're outside, even if the approaching storms aren't severe. Follow event officials' weather safety instructions.
