Scattered thunderstorms during the afternoon and evening hours produced pockets of heavy rainfall and very efficient rainfall rates. This resulted in localized flash flooding reports across far southeast South Dakota, far northeast Nebraska, and northwest Iowa. Even after the heaviest rainfall rates had ended, a stripe of prolonged moderate rainfall resulted in excessive ponding and some minor flooding of rural roads.
