Though London and south-east England will still get temperatures up to 27C, it won’t be 28C needed to officially continue the heatwave.
However, Wales and south-western England will remain fairly hot, away from the cooler air moving in. Highs here could still reach 30C.
By Thursday, the supply of cooler air will be cut off as hot air re-surges from France once again. This means that temperatures will increase, with 30C back on the cards.
Most weather forecast models show that cooler weather will gradually come in again from Friday and into the weekend.
The jet stream, currently to the north of us, will wobble back southwards, meaning areas of low pressure, occasional rain, stronger winds and a drop in temperature as we head into the first week of June.
