Information on update: The warning area has been shrunk to cover only central and eastern parts of Scotland, whilst the likelihood of impacts has increased. Whilst not all areas will be affected, heavy showers and thunderstorms are likely to develop in places during Thursday afternoon and evening across parts of central and eastern Scotland. These will be rather slow-moving, potentially giving rainfall accumulations of 20-40 mm in less than an hour and perhaps 50-70mm over 1-2 hours in one or two very isolated spots. This brings a chance of surface water flooding, as well as damage from lightning strikes and large hail. Showers and thunderstorms should slowly decay during the mid to late evening.
