The heatwave is returning for round two in London and the South East.
London set to sizzle again as heatwave returns
Temperatures could climb back up to 31C this weekend with almost unbroken sunshine.
Essentially at the end of the week we're looking at a bit of a north-west/south-east split in the weather. Northern and some western areas will often be cooler with some outbreaks of rain - particularly in Northern Ireland and that could spread in to the south and western Scotland.

On Friday, temperatures are likely to hit at least 29C and possibly 30C in southern parts of the UK.
Temperatures will continue to build, but nothing quite as hot as what we saw towards the end of last week. This weekend is much more promising than last weekend - plenty of sunshine around although the north of England could see a few showers on Saturday. The heat is likely to continue into next week. Temperatures will remain pretty hot across at least the south of England but potentially more widely across the UK - we could see some wet weather coming across the north west, but still pretty hot.

Holidaymakers heading to Spain and Portugal were warned of an extreme heatwave which could see the hottest-ever temperatures recorded in continental Europe.
The current record of 48C in Athens, Greece, in 1977 could be broken as wave of blisteringly hot air sweeps in from Africa.
Temperatures crept into the low 40s on Wednesday and are expected to rise and peak at the weekend, with the highs expected inland rather than in coastal areas.
