Forecasters have confirmed that while the heat will hit 26C today and 28C tomorrow, rain and thunderstorms are on the way.
The Met Office said the mercury would remain above average for this time of year over the coming days – with temperatures of 26C (79F) today and 28C (82F) tomorrow – but conditions will become more ‘unsettled’ later today.
The threat of showers today will be most frequent across western areas, although much of the rest of the UK will once again enjoy bright sunshine.
But tomorrow is likely to be a washout for many parts of the UK, with the South East expected to be particularly wet.
The Met Office has issued a yellow weather warning for thunderstorms covering much of England and Wales for tomorrow.

Forecasts say heavy showers and thunderstorms will develop across parts of England and Wales during Sunday, with longer spells of thundery rain in places.
Some places could see 1.2in (30mm) in an hour and 2.4in (60mm) in six hours, with the ‘potential for frequent lightning, strong winds and hail’.
Campers at the popular Isle of Wight face being flushed out of their tents by torrential downpours on Sunday, after enjoying days of scorching heat.
Headliners Robbie Williams and Niall Horan could see their sets interrupted by the bad weather after weather warnings were issued for Sunday.
Forecasters said there was a ‘high likelihood’ that thunderstorms will develop over England and Wales, but there ‘remains a large amount of uncertainty in exactly where these develop’.
They added that spray and sudden flooding could lead to difficult driving conditions and some road closures.
The Met Office also said there was a ‘small chance that homes and businesses could be flooded quickly, with damage to some buildings from floodwater, lightning strikes, hail or strong winds’.
Other possible disruption includes is a chance of delays and some cancellations to train and bus services, while power cuts could also occur – and there is a ‘small chance that some communities become cut off by flooded roads’.

The Met Office added that the risk of thundery showers for some is likely to continue into next week, but temperatures will remain above average for the time of year.
While most of the UK will remain dry and sunny for most of Saturday, Northern Ireland may already experience a weather change in the afternoon, with thundery showers and rain expected.
Met Office deputy chief meteorologist Steven Keates said: ‘Over the coming days we’ll be transitioning to a more unsettled regime for the UK, though temperatures will remain high and it’ll feel very humid for many.
‘Heavy showers and thunderstorms are likely to become more frequent through the weekend, with the potential for associated hail, lightning and some gusty winds.
‘While the focus of thundery showers on Friday afternoon will be Northern Ireland, that risk spreads more widely across western and southern areas of the UK on Saturday, before pushing further north on Sunday.
‘As in many of these situations, these showers can be hit or miss, with some places avoiding them whilst other areas nearby may see some very wet conditions.
‘There’s an ongoing likelihood of warnings being issued in the coming days, so keep an eye on the weather forecast for the latest outlook.’
The Met Office said it is still establishing where the heaviest thundery rain will be at the weekend, but more than 1.6in (40mm) of rain could fall in some places in short period tomorrow and on Sunday.
But they added that the most likely exception to the unsettled shift in conditions is over north-eastern parts of Scotland, which will enjoy the dry weather for the longest.
The Environment Agency warned of possible surface water flooding across England on Sunday afternoon due to the downpour of rain.
Despite more thundery conditions being on the way, temperatures will remain high while a plume of warm air still influences conditions in Britain.
The Met Office said the mercury would likely remain in the mid-to-high 20Cs for some throughout the weekend, although some places could dip slightly below the threshold for the official heatwave to continue.
The threshold for a heatwave is different across the UK. In some areas it is classified as hitting highs of 25C (77F) to 28C (82F) across a three-day period.
Forecasters said maximums would range between 24C (75F) and 27C (81F) in most of England, Wales and Scotland today, although the North East and far South West could be closer to 21C (70F) or 22C (72F).
Tomorrow will be a similar story, with highs of 26C (79F) expected in the South East, and 21C (70F) to 25C (77F) elsewhere across Britain.
Sunday is looking even warmer, with Birmingham the UK hotspot at 28C (82F) and London close behind at 27C (81F). Temperatures for the rest of Britain will range between 18C (64F) and 26C (79F).

The Met Office also said night-time temperatures will remain well above average, providing ‘little relief to those more vulnerable to high temperatures’.
Dan Stroud, a spokesman for the Met Office, said conditions would become ‘increasingly humid and uncomfortable’ over the weekend, especially in inner cities, with temperatures unlikely to drop below the 20Cs overnight.
The UK Health Security Agency, which covers the healthcare sector in England, has a Heat Health Alert in force.
It comes as an NHS medical director said the heat had contributed to one of the ‘busiest days ever’ in A&E departments across the country yesterday.

NHS national medical director Professor Sir Stephen Powis added: ‘We know the warm weather has increased demand on services and this week we have seen one of our busiest days ever at A&E departments.
‘As we move into what’s forecasted to be a very warm weekend, the heat and the impact of industrial action will continue across the country.
‘NHS staff are working hard and prioritising urgent and emergency care, so as ever, use 999 in emergency and life-threatening situations and NHS 111 online for other health concerns.’
A UK Health Security Agency spokesman warned that the sustained heat could impact the health and social care sector.
She said: ‘If current forecasted temperatures are reached it is likely that there could be some impacts across the health and social care sector.
‘A yellow alert means that any impacts include the increased use of health care services by vulnerable populations and an increase in risk to health for individuals over the age of 65 or those with pre-existing health conditions, including respiratory and cardiovascular diseases.
‘If you have friends, family or neighbours who you know are more vulnerable to the effects of hot weather, it is important you check in on them and ensure they are aware of the forecasts and are following the necessary advice.’
Meanwhile, South East Water bosses said a hosepipe ban is set to come in across Kent and Sussex due to a record demand for drinking water.
Areas of the region have been left with little or no water this week amid the hot weather, forcing schools to shut and residents to get drinking water from bottled water stations.
A plea to use only essential water has stretched from Haywards Heath in West Sussex to Whitstable in Kent.
The temporary ban on hosepipes and sprinklers will come in on June 26.
South East Water said despite providing an extra 120 million litres of water a day, demand in June has broken records, including from the Covid lockdown heatwave.

David Hinton, the firm’s chief executive, said: ‘This situation has developed much more rapidly than last year. Understandably, we’ve seen customer demand increase in line with the hotter weather, however this has impacted our ability to keep all customers in supply at all times.
‘Despite asking for customers’ help to use water for essential uses only, regrettably we’ve now been left with no choice but to introduce this temporary use ban restriction to protect customers’ supplies across Kent and Sussex.’
Mr Hinton said the long-term forecast for the summer is a dry period with little rainfall, adding: ‘Restricting the use of hosepipes and sprinklers to make sure we have enough water for our customers’ essential use will ensure we can serve our vulnerable customers and to protect the local environment.’
On Friday, three schools in East Sussex partially closed due to water shortages.
Mark Cross Church of England Primary School in Crowborough said it could not open to all year groups because of reduced sanitary facilities and no running water.
Areas experiencing no or low water pressure during the week include Crowborough, Wadhurst, Mayfield, Lewes, Newhaven in East Sussex, and Biddenden, Staplehurst, Cranbrook and Ashford in Kent.
Wealden MP Nusrat Ghani has been calling on South East Water to introduce a hosepipe ban since earlier this week, blasting the company for ‘appalling’ outages across her East Sussex constituency.
Last Saturday was the UK’s hottest day of the year so far, with 32.2C (90F) recorded at Chertsey in Surrey.
The Met Office said it was also the first time temperatures had got above 30C (86F) in the UK since August 24, 2022.
