Upper trough will migrate eastwards across the British Isles on Friday. On the forward side, strong shear and forcing will promote elements of line convection on the rear side of the cold front precipitation envelope as it moves across England during the morning hours. Squally winds and heavy rain will be possible locally, but saturated profiles and weak instability suggests the risk of lightning is fairly low (but non-zero).
