Weather Briefing Video

Lightning flashed and thunder rumbled as a strong thunderstorm moved across Black Hawk County, Iowa. The downpour dropped about an inch of rain in 30 minutes with street flooding reported in some areas. At my location the storm was not severe - winds were light, there was no hail, and the rain intensity ranged from moderate to heavy. As the storm moved southeast high winds and hail were reported with numerous severe thunderstorm warnings being issued.
