"July CU and CI"

Fair weather cumulus (CU) developed early Sunday afternoon. There was more cumulus over the American shore with a minimum over the St Lawrence River. It was apparently holy cumulus - appropriate for a Sunday. A few of the cumulus towered rapidly upward with the crazy wind shear and then was quickly torn apart. The towering cumulus tops sheared up river with the outflow from a high pressure area to the north.

There was a backdrop of cirrostratus (CS) far to the south. In addition there were a few tentacles of fair weather cirrus (CI) in the upper right of the image. The low pressure area far to the south was never a threat for rain along the St Lawrence River.
