Superior Little Cb
This scene typifies a small cumulonimbus moving toward the viewer, its anvil beginning to spread almost symmetrically off the top of the convective towers. A rocky beach along the northeast corner of Lake Superior framed this shot, beneath a fortunate northwesterly flow regime that kept ambient skies clean of haze with visibility sharp. A small stratus deck in the low foreground hid the storm's base, but only temporarily. It moved SE and grew into a photogenic multicell with a pronounced shelf cloud.1 W Michipicoten River Village, ON, Canada (15 Jul 7) , looking N.
