Main interest during this forecast period will be on Sunday morning as the upper trough axis, initially over southern Britain, clears to the southeast. Showers will be numerous across England and Wales at first, but becoming increasingly restricted to Wales / Cheshire Gap Effect as upper forcing weakens in the wake of the departing upper trough. Therefore the greatest risk of lightning, albeit still quite low, will be between 06z - 10z. Showers will occur elsewhere, but with a very low risk of lightning.
