Upper trough migrating into Iberia will cause the flow over France to subtly back, allowing advection of a higher WBPT airmass back into southern Britain. On the eastern edge of this plume, some elevated instability will be present across NE France / BeNeLux, drawn into SE England and East Anglia during the early hours of Wednesday. It is questionable whether there will be sufficient forcing to destabilise the mid-levels, but there could be scope for isolated lightning from any showery outbreaks of rain that develop here.
