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!

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.
