The Extreme heat warning, which covers much of the southern half of England as well as parts of eastern Wales, will be in force from Thursday through until the end of Sunday with impacts possible to health, transport and infrastructure.
The heat will build through the week, peaking on Friday and Saturday thanks to the influence of high pressure positioned over the UK. Temperatures are likely to rise into the low-to-mid 30s Celsius for those within the warning area. However, temperatures are not expected to be as extreme as those experienced in July when new national records were set.
Outside the warning area, heatwave criteria are still likely to be met for much of the UK, with temperatures widely into the high 20s Celsius with a chance of a few spots seeing temperatures into the low 30s. Scotland and Northern Ireland will also see temperatures into the high 20s and could reach official heatwave criteria by Friday.
