An upper trough axis will move northeastwards across Britain and Ireland on Sunday, while extending. At the surface, cloud and rain associated with a frontal system will gradually clear Scotland and eastern England, followed quite widely by a showery airmass as cold air aloft overspreads relatively warm SSTs and diurnal heating inland. Numerous showers are expected to develop through the day, initially across Ireland but extending to much of Scotland, with a few also likely scattered across England and Wales. Showers will at times become organised into distinct lines where local topography aids convergence, such as peninsular and estuary convergence parallel to the southwesterly flow. Showers may become organised into a more active cluster across Ireland from late morning, spreading into Scotland during the afternoon.
