The relationship between the low-level jet and thunderstorm activity in the south-central United States is examined through mesoanalysis of surface data from Weather Bureau and NSSP stations. Separate squall systems were found to move through Kansas and Oklahoma during the night the systems in Kansas persisted, while those in Oklahoma died out. The reason for this seemed to be associated with the vertical velocity fields at low levels. It is postulated that the orientation of thunderstorms with respect to the jet maximum may be an important factor in determining whether or not they will survive for any appreciable period of time.
