Upper trough axis will slide southeastwards across Britain on Sunday, the associated cold pool aloft generating steep mid-level lapse rates and a few hundred J/kg CAPE in response to SSTs and diurnal heating inland. Showers near coasts initially, fuelled by the relative warmth of the sea, will become more numerous inland during the day. Hail (and snow) is likely in many of the showers, and the strongest cells could produce a few sporadic lightning strikes - although given the fairly shallow nature of convection the risk is generally quite low in any one location.
