Britons are basking in yet another gloriously hot day today but be alert – thunderstorms are coming.
Today the mercury is set to reach 30C again although the Met Office has issued a yellow warning for thunderstorms and rain tomorrow.
The nation is making the most of the weekend weather with people taking to parks and beaches and having BBQs at home.
An estimated 100,000 holidaymakers have flocked to the Bournemouth area to soak up some rays and the roads approaching the Dorset seaside town are gridlocked.
Yesterdays top temperature was 32.5C (90.5F) in Porthmadog, Wales, making it the hottest place for three days in a row.
This compares with average temperatures for the time of year of 17C (62.6F) in the north and 21C (69.8F) in the south.
Met Office meteorologist Steven Keates said that on Saturday it will be sunny pretty much across the board.
He said: Temperatures are set to reach the mid to upper 20s widely, probably close to 30 to the west of London and also for the likes of Porthmadog again.
Then on Saturday night he said it would be dry and clear for many.
He added: There will be some patchy low cloud eastern Scotland and northeast England, turning humid in the south, lows in Plymouth, for example, may not be much lower than 18 or 19C.
There is a risk of thunderstorms into the far southwest by morning.
It follows on from hosepipe bans in Northern Ireland and Severn Trent Water asking customers to be careful with their usage.
The rising temperatures have also brought warnings to be careful near water and in the countryside, where fire crews have been tackling wildfires.
The Met Offices heat-health watch alert is currently at level two, meaning social and healthcare services are at the ready to reduce harm from a potential heatwave.
Public Health England has issued a warning saying the extreme heat may pose a risk to the most vulnerable.
By Sunday its expected to still be another dry and warm day, although there is a risk of thunderstorms in southwest England and later south Wales with a yellow warning issued.
Mr Keates added: Not everywhere will see rain, but localised torrential downpours are possible.
Also northwest Scotland will turning cloudier and a bit damp later.
Top temperatures will be 31 to 32C again in west London across to the Bristol area.
