Ballyclare, Northern Ireland, United Kingdom Severe Weather Alertstar_ratehome

Whilst not all areas will be affected, heavy showers and thunderstorms may develop in places during the early hours of Thursday and into Thursday morning, perhaps merging into some larger areas of rain. Where heavy downpours occur, 20-40 mm of rain could accumulate in less than an hour, bringing the risk of some surface water flooding. Hail and lightning will be additional hazards.

Further scattered heavy showers and thunderstorms are then likely to develop on Thursday afternoon and evening across portions of central and eastern Scotland in particular. These will be rather slow-moving, potentially giving isolated accumulations of 40-60 mm in an hour, with a higher likelihood of some impacts from surface water flooding. Showers and thunderstorms should slowly decay during the mid to late evening.
