A strong cyclonic SW-W flow covers the UK circulating around upper low centred to the N of Scotland. A shortwave trough in the circulation will shift east across England & Wales through Saturday morning, before clearing E in the early afternoon. Lapse rates will steepen with passage of this trough and large scale ascent will be enhanced ahead of the trough, supporting an uptick in heavy showers spreading from the west across England and Wales through the morning and early afternoon before easing from the west. There should be sufficient CAPE across southern Wales, Midlands, S England and E Anglia for some of the heavy showers to produce isolated lightning and some hail.
