What Is Updraft?
A current of rising air inside a cloud or storm. Strong updrafts build tall storms and hold hail aloft. In technical terms: A localized region of upward vertical motion; in deep convection driven chiefly by buoyancy, with maximum theoretical speed approximately √(2·CAPE), commonly 10-50 m/s in severe storms.
