Shortwave over Biscay continues to destabilise the mid-levels over the coming hours, with sporadic pulses of rain moving NE-wards across south and southeast England through this evening and overnight. Most lightning activity will likely remain over France where instability is greater, but a few sporadic lightning strikes will be possible in parts of SE England. 


Later in the night, steepening lapse rates associated with the approaching upper trough will bring a marginal threat for some isolated / sporadic lightning into NW Scotland, as scattered showers move in from the Atlantic.
