UPDATE 13:35 UTC SLGT extended westwards to include active thunderstorm cluster over NW England

Upper trough swings NEwards across British Isles through Sunday, with cold air aloft steepening lapse rates in response to diurnal heating. Scattered showers and a few weakly-electrified thunderstorms will develop, sometimes becoming organised into bands, with the greatest chance/coverage of lightning expected in the two SLGT areas - moreso in the eastern zone from S Yorks down to Lincs. Even so, only a low-end SLGT has been issued, but for many it will be the first proper convective day of the year.

Small hail is likely to accompany some of the showers, and given some LLS, particularly in the eastern SLGT, there is scope for perhaps a funnel or weak tornado.
