Heading For Trouble

An isolated severe storm cell looms in the distance as I headed north along Highway 13 just north of Marion, Iowa and approaching the intersection of County Home Road around 7:04 PM, Wednesday, June 26, 2013. I wasn't trying to intercept the storm (it was 85 miles away I later discovered) but to get closer to more effectively photograph it. I would eventually stop at the town of Coggon, about 13.5 miles from this position. The cumulonimbus sported an overshooting top, attesting to its strong updraft condition. The isolated storm was the only one for hundreds of miles and was located in Allamakee County, Iowa, along the Minnesota border.
