Outbreaks of rain with embedded line convection will continue to migrate northeastwards across the British Isles through Wednesday. The main attention turns to the post-frontal environment where a zone of steeper mid-level lapse rates tracks eastwards through the afternoon across Ireland, and then Britain through the evening and night. Numerous showers are likely to develop over seas, and drift inland on the southwesterly steering winds - and so the main focus will be southern and western coasts exposed to the onshore wind. The greatest risk of a few isolated lightning strikes is probably over the English Channel and into southern coastal counties of England on Wednesday night, where some rather squally winds will also be possible.
