Several NBC12 viewers sent in pictures of a cloud that is eerily shaped to resemble that of an atomic bomb explosion. So what was it exactly?
Kevin Jeanes explains:
"With the lack of upper level winds and strong daytime heating, a few storms popped straight up and didn't move.
"The top of the clouds hit an inversion in the atmosphere so it fans out and creates an anvil shape. Storms don't last long without upper winds steering them along."
