Hi, Tash: Tornadoes result from a number of factors combining, but often they are part of weather systems traveling along a pressure ridge, or border between (usually) air masses of different temperatures (and thus pressure). Think of it as a big storm train sliding along that ridge (which itself is usually moving as one line west to east), with some of the cars being tornadoes, some being big thunderstorms, some being just rain, some being just wind, and so on. So what sometimes happens is that there are “cars” traveling behind the tornado that themselves carry big storms. Thanks for asking!
