The Met Office has said that on Tuesday rain will move eastwards across southern counties of England and Wales, bringing blustery conditions and heavy downpours in places.
Elsewhere, a mix of sunny spells and scattered showers is likely, with lighter winds. Highs of 20-22°C are expected in the south and southeast, with temperatures widely in the high teens further north.
Rebekah Hicks, Chief Meteorologist at the Met Office said, “We’re expecting a band of heavy rain and strong winds to move northeast through the first part of Wednesday, followed by heavy showers and the risk of thunderstorms. Some of these could bring hail and gusty winds, particularly in southern areas.
“Of course, the warning coincides with the first school run after the summer holidays for some, meaning a wet and potentially disruptive start to the day for many.”

The Met Office said that Thursday looks to be unsettled, with widespread showers and occasional thunderstorms. Some sunny spells are expected, but rain may become more persistent in parts of western Scotland. Winds will stay brisk, especially near coasts, and temperatures will be around average for the time of year, in the high teens to low 20s.
By Friday, southern areas will begin to see more settled conditions, with increasing sunshine and fewer showers. However, the northwest will remain wet and windy, with a small chance of coastal gales.
