Elsewhere, an Atlantic frontal system will spread cloud and rain northeastwards across all parts of the British Isles during this forecast period. The trailing cold front approaching SW England during the early hours of Saturday is likely to contain some embedded line convection, given the strongly-sheared environment, which could produce some gusty winds - but the risk of lightning is considered very low. This embedded line convection will continue to track northeastwards across south Wales into the Midlands and central southern England towards the end of the night.

Perhaps the main interest (from a lightning perspective) in this forecast period will be associated with the post-frontal environment, as a cold pool overspreads the relatively warm seas around Ireland during the early hours. This will lead to an increase in shower activity, coupled with steepening mid-level lapse rates and 300-500 J/kg CAPE. As such, a few isolated lightning strikes are possible later in the night.
