A view toward the west or northeast, often with revealing backlighting, typically offers the best view. This is the same Itaska, Texas storm, seen through a telephoto lens, looking west from about 15 miles! Photograph by: NWS Such spectacular distant views are relatively rare, especially in the east and southeast U.S. where low clouds, haze, precipitation, trees, and hills make spotting from a distance more difficult.
The indentation on the left side of the Cb in this photo seems to verify the presence of a rear flank downdraft (RFD), with a clear distinction between hard-textured updraft cloud and the ragged, dissipating cloud elements caught in the RFD. The tornado is at the intersecting point of the rotating updraft and RFD.
