A minor shortwave will drift eastwards across England and Wales on Saturday, and may deepen the boundary layer sufficiently to allow a few locally heavy showers to develop in response to diurnal heating. However, given substantial subsidence above 700mb, depth of convection will be restricted and so the risk of lightning is considered very low (5-10%).
