Forecasts indicated a southeastward-moving trough organising into a line of convection NE of Chilbolton by the early afternoon, so scanning focused on this sector. In the early morning showers originate over Devon and Somerset, travelling eastward and by late afternoon these have organised in a line stretched along the South coast. Scans in the early afternoon focus on the sector south of Chilbolton. Towards the evening, a line of thunderstorms had organised from south Wales to Surrey, and scans were focused on these mainly NE of Chilbolton.
