A band of heavy and thundery showers may develop early Thursday morning over the east of Northern Ireland and the southwest of Scotland. If these develop they will move northwestwards bringing frequent lightning, locally intense rainfall and perhaps hail. 30-40 mm of rainfall could fall in an hour or so with perhaps 60-70 mm in 3 hours. The thunderstorms should ease after sunrise but may take much of the morning to finally die out.

An area of thundery showers may develop from early Thursday morning bringing disruption from lightning, heavy rainfall and hail.

Areas of thunderstorms are expected to develop over Wales and parts of England during Thursday. Some intense thunderstorms seem likely, associated with torrential rain, large hail and frequent lightning, as well as strong gusty winds. Rainfall totals of 30-40 mm could fall in less than an hour, and a few unlucky locations could receive 60-80 mm in 3 hours. There is even a very small chance of extremely high totals (exceeding 100 mm ) in 3 or 4 hours.

While some areas stay dry, others could see severe thunderstorms, with possible sudden flooding, or damage from lightning or hail.

Areas of showers and thunderstorms associated with a hot and humid air mass stranded across the southern half of the UK are expected to continue through Friday, with some continuing overnight into Saturday morning. Many areas encompassed by this warning will miss the thunderstorms altogether, but where they occur, heavy rain (20-30mm in an hour, and possibly as much as 50mm in 2 to 3 hours), frequent lightning, and in some places large hail are all potential hazards. The greatest chance of impactful showers is expected to be in the southern half of this warning area, where afternoon showers are more likely to be slow moving and prolonged.

Further heavy showers and thunderstorms are expected at times and may lead to some flooding or travel disruption
