Under The Lip

The higher altitude, leading edge of the coming thunderstorm is shown in these two images both taken around 7:36 PM, Thursday, July 25, 2013. Both were shot from North Marion Road, about one-tenth mile north of County Home Road (seen in the background of the top image) and about 2.5 miles north of Marion, Iowa. In both images, the cloud edge is moving toward the patch of blue sky. The top image looks southeast, the bottom, southwest. The storm arrived in the Cedar Rapids area about an hour and a half later. Total rainfall from the storm on my gauge indicated 1.76 inches--much needed--as conditions had been dry for a couple of weeks.
