Note how the thunderstorms keep passing over the same narrow region from Beatrice (BIE) to
near Sioux City (SUX).  This phenomenon of thunderstorms repeatedly passing over the same location is
often referred to as "training" i.e. similar to a train of cars passing down a track.  The blue area on
the radar image in Wyoming and Colorado is SNOW!
