Waiting For The Blow-Through

This was the appearance of the west sky as seen from White Road in Linn County, Iowa, a half-mile east of North Alburnett Road (W58) and about 4 miles north of Marion, Iowa. I had taken up a spotting position at this farm field entrance. The approaching line of storms were configured in a gust front. Photos were taken around 12:08 PM CDT, Sunday, June 22, 2014.
