A messy picture will dominate across the British Isles on Saturday, with a near-stationary occlusion lingering across northern Scotland bringing outbreaks of rain here for much of the forecast period. Also, on Saturday night a frontal wave will bring a renewed pulse of rain across southern Britain. Away from these features, some scope for deep convection to occur, though generally limited somewhat in depth, especially across southern parts. 

Nonetheless, a few sporadic lightning strikes will be possible associated with showers developing over seas, then drifting farther inland courtesy of the westerly steering flow. The greatest risk of lightning, albeit still low, is over western Ireland during Saturday daytime, and then increasingly across the Celtic Sea on Saturday night into Sunday morning as the sharpening upper trough approaches from the Atlantic.
