Given the environment, there is a widespread (but reasonably low per given location) risk of a few isolated lightning strikes. Instability is likely to be greatest near the west coast of Scotland during the day, shifting to the English Channel for the overnight hours. However, strong speed shear (fairly unidirectional shear with height) will exist over southern Britain during the day and this may be enough to compensate for the weaker instability to aid some organisation and produce a few isolated lightning strikes. Confidence is not high enough in any one location to introduce a SLGT, although climatologically favoured areas would be W Scotland, NW England, S Wales.

One limiting factor may be the true depth of convection across central / southern Britain (deeper convection more likely further north, especially during daylight hours). Nonetheless, strong convective gusts and small hail will accompany several of the showers.
