Under The Anvil

This image looks south along US Highway 218 at 160th Street, about 4.3 miles south of the Riverside, Iowa exit on the evening of June 7, 2015. Even though the anvil appears to be overhead, the leading edge is actually about 7 miles distant. I was headed for Henry County, where severe weather was approaching.

The middle image shows a radar capture at the time of the top photo (4:52 pm CDT), with the white dot showing my southbound position in relation to the storm. The green color at upper right is the anvil. Storm movement was to the ENE.

Bottom image, captured about three minutes later, looks generally east while southbound on US Highway 218. Mammatus formations can be seen under the local storm cell anvil. Along the horizon at center, the updraft of another storm cell can be seen. This storm was located some 90 miles to the northeast, in southern Whiteside County, Illinois. Nikon D5000 DSLR camera.
