UK heatwave: Temperature record could be broken this week
- Published
BBC Weather forecast for the rest of the week - predicting highs of around 36C
The UK's all-time temperature record could be broken by Friday as the hot and dry summer continues.
Highs of up to 37C (99F) are forecast in southern, eastern and central England, but the Met Office says "if conditions all come together", the record of 38.5C (101F) could be beaten.
That was set in Kent in August 2003.
But much of England could experience thunderstorms and hail showers on Friday, bringing the risk of flash flooding.
Some places could see as much as 30mm of rainfall in an hour and 60mm in three hours.
Meanwhile, fire crews are urging people enjoying barbecues and other outdoor activities in dry areas to avoid "careless and reckless" behaviour that could start a blaze.

Hospitals, too, have been affected by the heat.
Kim Sun-Lee, national officer at the Royal College of Nursing, told the BBC: "We know wards are reaching over 30C, nurses are feeling sick, dizzy, having problems with their concentration.
"And that then does have an impact on how they care for their patients, making decisions around drugs calculations and just generally doing a physical occupation."
The number of people visiting the NHS Choices website for advice on heat exhaustion and heatstroke has more than quadrupled compared to last year.
Up to July 23, there were 230,611 visits to the page, while in the whole of July 2017 there were only 52,143.

Head of gardens Steve Porter said he had known the designs that date back to 1699 were hidden underneath the lawn.
2018 and 1976 - a tale of two heatwaves

In 1976, the high pressure system was centred further to the east of the UK than now.
That had the effect of drawing up hot humid air from the south, making night-time temperatures even hotter than they have been this year.
The exact location of systems such as this really matters because the UK is relatively small - so a shift one way or the other can have a big effect.
So what about the actual heat?
This is no comfort to anyone toiling outdoors now, but 1976 was in a different league to this year.
