Overall discharge could be higher after a previous storm as ground may be waterlogged, and so any water which could before be slowed by through flow and percolation etc would just run off the surface due to ground saturation. This would not only shorten the lag time but increase overall discharge as more water will eventually reach the river. Hope that helps!
