Thunderstorms began developing over northwest Iowa shortly after midnight on August, 2019. While storms started out as discrete storms producing mainly small hail and locally heavy rainfall, they gradually merged and the threat transitioned to a wind and tornado event. By 4 to 7 am storms were pushing across central Iowa, producing areas of straight line wind damage with several embedded tornadoes along the front edge of the line. As storms continued to push south the tornado threat diminished, but storms continued to produce heavy rain and gusty winds across the line of storms.
