Drawing on my earlier research days attempting to grow mathematically simulated, intense thunderstorms on a Cray supercomputer, I can attest to the nonlinearity of the atmosphere: Very slight changes in the thermodynamic environment of a storm can have disproportionately large profoundly large impacts on the response of cloud systems, most notably the vigor and depth of cloud updrafts. For example, the wealth of computer model runs issued before the event can be compared with data from special efforts like the TORUS field campaign, to figure out what the models did and didnt capture ahead of time.
