Upper trough will approach from the Atlantic on Sunday, cold pool aloft serving to steepen mid-level lapse rates - primarily over Ireland. A couple of occlusion/trough features will provide the focus for bands of showery rain moving NE-wards through the day, turning increasingly convective in nature in response to some diurnal heating. Some sporadic / isolated lightning is possible from the strongest cells - particular focus is given to the north Midlands into Yorkshire / Lincolnshire (and perhaps Norfolk) where low-level convergence may enhance some forced ascent, but lightning coverage is not expected to be significant enough to upgrade to SLGT.
