A generalization of the single-parameter scaling theory of localization is proposed for the case when the random potential depends on temperature. The scaling equation describing the behavior of the resistance is derived. It is shown that the competition between the metallic-like temperature dependence of the Drude resistivity and localization leads to a maximum (minimum) at higher (lower) temperatures. An illustration of a metal-insulator transition in the model of charged traps, whose concentration depends on temperature, is presented.
