It's a place of sudden temperature drops with the potential for strong winds as cold air aloft descends to the surface. This storm turned out to be a typical Iowa summer thunderstorm when it crossed Black Hawk County, Iowa. In this case the winds were light at the surface while clouds aloft rushed to the southeast. This video shows cloud formations along the front of the storm and you will see lightning flashes followed by thunder. There was no severe weather here but we did receive about an inch of rain in about 30 minutes.
