Behind a southward-moving cold front on Thursday night, a cold airmass of Arctic origin will advect southwards across the northern half of the British Isles by Friday morning. This cold air atop relative warm SSTs will result in a few hundred J/kg CAPE, with numerous showers likely which may produce some small hail and a few sporadic lightning strikes (snow also likely over the Scottish mountains).
