A cold front will slide southeastwards across Ireland and Scotland on Friday, weakening significantly by the time it reaches Wales and northern England during the afternoon. However, a for a time some elements of line convection seem likely given a narrow tongue of warm, moist low-level air within a strongly-sheared environment and marked wind veer as the front moves through - this perhaps most notable in Ireland. 


The post-frontal environment will then be characterised by steepening mid-level lapse rates as cold air aloft overspreads relatively warm SSTs, generating a couple hundred J/kg CAPE. Numerous showers will affect north and west Scotland, with a few isolated lightning strikes possible along with small hail.
