Overview

 

A slow moving area of low pressure sparked numerous thunderstorms across the area on Saturday August 5, 2023. This resulted in a widespread 1 - 1.5 inches of rain with the highest totals exceeding 6+ inches of rain. Some locations reported over 10 inches of rain. Despite this, only localized areas of flash flooding were reported - mainly in Sioux county, IA and Kingsbury county, SD. Antecedent drought conditions limited impacts including rises on area rivers. There were also a few rotating storms which produced 2 tornadoes. Rainfall continued off and on into the Sunday, although rainfall amounts were much less.
