Weekend to bring cooldown after record-breaking heatwave

Temperatures on Saturday will drop back to the mid to high teens for many, although still around 17-20C for the south-east of England and there have been some overnight thunderstorms too. High pressure, which has been responsible for the sunshine and heat, is starting to retreat eastwards and low pressure is centred to the north-west of the UK, bringing weather fronts in from the Atlantic. The wind will be turning from a southerly to more of a westerly bringing about the change to cooler conditions. Despite a cloudy start, Scotland will see a mixture of sunny spells and scattered showers developing for most, heavy in places and locally thundery.
