On Friday, an upper trough will move east across the British Isles behind surface low moving out over the North Sea from NE Britain towards Norway. A moist southwesterly flow will cover southern Britain during the day, lapse rates will steepen as upper trough moves in from the west creating 400-500 j/kg CAPE with modest surface heating. This instability and large-scale ascent of moist airmass ahead of upper trough will support the development of heavy showers and thunderstorms moving east. This convection may be accompanied by hail, gusty winds, C-G lightning and brief intense rainfall leading to localised flooding. Any storms should clear east during early evening.
