Massive Shelf Cloud

shelf cloud is a low, horizontal, wedge-shaped arcus cloud. A shelf cloud is attached to the base of the parent cloud, which is usually a thunderstorm, but could form on any type of convective clouds. Rising cloud motion often can be seen in the leading (outer) part of the shelf cloud, while the underside often appears turbulent and wind-torn. Cool, sinking air from a storm cloud's downdraft spreads out across the land surface, with the leading edge called a gust front. This outflow cuts under warm air being drawn into the storm's updraft. As the lower cooler air lifts the warm moist air, its water condenses, creating a cloud which often rolls with the different winds above and below (wind shear). People seeing a shelf cloud may believe they have seen a wall cloud. This is a likely mistake, since an approaching shelf cloud appears to form a wall made of cloud. A shelf cloud usually appears on the leading edge of a storm, and a wall cloud will usually be at the rear of the storm. A sharp, strong gust front will cause the lowest part of the leading edge of a shelf cloud to be ragged and lined with rising fractus clouds. In a severe case there will be vortices along the edge, with twisting masses of scud that may reach to the ground or be accompanied by rising dust. A very low shelf cloud accompanied by these signs is the best indicator that a potentially violent wind squall is approaching. An extreme example of this phenomenon looks almost like a tornado and is known as a gustnado.[1]

That is pretty cool!

Amazing weather phenomena we see these days.

Cool find

Mother Nature is a bitch, I did see this video earlier today but thanks to you for taking the time to post it.

Personally we have never seen one even close to that magnitude but rest assured if we did see one like that if would be new panties and undies required for all

Holy crap! Where is that happening? Is it happening now? Take cover!!! That's some scary stuff, I don't ever play with mother nature if something bad like that is happening. You just never know, you have to respect her! She is strong and Unbiased ! ...I bet the air under that cloud is dead air...erily dead and no noise! Like a vacuum!

yes ! funny you should say that , when i first viewed the thread , i was looking for any type of strange UFO

I can't count the number of times I have come to the Fragile Earth forum to be awed and amazed by something posted by a member. That was beautiful.
Thank you for sharing it.
Looked like some pretty nasty weather was on it's way, though.

wait , so was it a lightning strikes ?

meh..that's a typical day in April here in southern Illinois..I have seen much worse..happens in the spring and in the fall here..about every 4 to 5 days...

I like neat looking clouds. My granddaughter and I saw a cloud that was shaped just like a Huge flying goose one day. It was spring and the goose cloud was flying south

Awesome video. Thanks for sharing.

It reminds me of this one I saw a while back;



Those things are impressive!
