The entire lifetime of a thunderstorm can vary. Typical afternoon thun â¦ derstorms in the summer usually consist of just 1 cell, thus lasts 20-30 minutes. Severe thunderstorms can consist of numerous cells, and last several hours.
A better way to classify storms is to base the categories on their actual physical characteristics. There is actually a continuous spectrum of thunderstorm types, but there are four broad categories of storms that will be discussed single cell storms, multicell cluster storms, multicell line storms, and supercell storms. Single cell thunderstorms have lifetimes of 20-30 minutes.
