We examine whether the now tube along the edge of a coronal streamer supports standing shocks in the inner slow wind by solving an isothermal wind model in terms of the Lambert W function. It is shown that solutions with standing shocks do exist and they exist in a broad area in the parameter space characterizing the wind temperature and now tube. In particular, streamers with cusps located at a heliocentric distance ≳ 3.2R⊙ can readily support discontinuous slow winds with temperatures barely higher than 1 MK.
