Unlikely I'm afraid.......
During the evening hours, a band or cluster of thunderstorms over northern France will begin to drift north across the English Channel, potentially affecting the Channel Islands for a time - it is unclear where these storms will survive the crossing, but the vast majority of model guidance is in agreement that they will decay fairly rapidly after leaving the coast, with lightning activity tending to hug the French coastline to the east. Nonetheless, a few elevated thunderstorms may be possible across S / SE England overnight, and perhaps at the end of the night close to the East Anglia coast.
