Broad upper trough to the NW of Britain on Sunday, accompanied by some marginal instability in the post-frontal airmass. Shortwaves rotating around the parent trough will provide the focus for deep convection, with scattered showers likely across Northern Ireland, western Scotland and northern portions of the Republic of Ireland during Sunday daytime, the risk then transferring across the remainder of Scotland overnight. Some isolated lightning will be possible.
An increase in elevated instability release seems likely later in the night near the frontal boundary, with lightning perhaps increasing in coverage over the northern North Sea, close to Shetland / Orkney.
