An upper trough will approach from the Atlantic on Tuesday, with a frontal system sliding southeastwards across the British Isles. The trailing cold front may contain some embedded elevated convection, particularly on Tuesday night across the Celtic / Irish Seas and feeding into western parts of Britain - but the risk of lightning is considered quite low.
The post-frontal environment will be characterised by cool air aloft atop warm SSTs, generating a few hundred J/kg CAPE. Periods of showers will affect western Ireland and Scotland through Tuesday evening and night, with a few isolated lightning strikes possible.
