Closed upper low west of Scotland will begin to fill, with heights aloft slowly rising, and morphing into a broad positively-tilted longwave trough, stretching from west of Iberia to Scandinavia. The associated cool mid-levels atop relatively warm SSTs and diurnal heating inland will result in another day of scattered showers and a few thunderstorms, primarily focussed over Scotland and Northern Ireland where the best mid-level lapse rates will be found. Farther south, profiles exhibit more capping and hence any showers here will be more isolated and less likely to produce lightning given limited depth.
