The next Atlantic frontal system will spread bands of cloud and rain across many parts of the British Isles through Wednesday and Wednesday night. The passage of the second occlusion will be within an environment with a few hundred J/kg CAPE over the open waters of the Celtic / Irish Seas and English Channel, and this combined with engagement with the left exit of a mid-level jet is likely to result in an increase of embedded convection, and so a few isolated lightning strikes may occur during the evening hours - primarily over open seas, but also potentially close to coastal areas in the south and west.
