Experiments on the flow development along the first diameter of a low Mach number jet are described. It is shown that the flow is governed by a local shear layer instability coupled with a feedback mechanism that determines the positions of the nonlinear amplitude saturation of the unstable modes. The spreading is a stepwise phenomenon associated with the saturation locations. In general these locations move randomly in time and space, resulting on the average in a linear spreading rate.
