Normally, there are three stages of thunderstorm development; they are i) cumulus stage, ii) mature stage, and iii) dissipating stage.
In the dissipating stage which is after about 30 minutes, when the thunderstorm begins. It is observed to occur when the downdraft's in the cloud begins to dominate over the updraft.
