Current thinking is cloud is most likely to break up across East Anglia and perhaps SE England, and diurnal heating will lead to the development of sea breeze convergence. Assuming this occurs, scattered slow-moving heavy showers and a few thunderstorms will be possible during the afternoon and evening hours. CAPE is notably lower than previous days and combined with weak shear will preclude most severe hazards - hail up to 1.5cm in diameter is possible, but the main threat is the risk of flash flooding, given PWAT still in the 35-40mm range. An isolated tornado is possible where low-level vorticity along convergence zones gets ingested. A few isolated heavy showers or weak thunderstorms may also develop in parts of S / SW Ireland and W / NW Wales. If more substantial cloud breaks develop across southern England then the risk may also increase here too, but confidence is too low to justify a SLGT at this stage.
