TEMPERATURES soared to 32C yesterday as a huge number of sunseekers made a beeline for Brighton beach.

Across the UK the mercury soared even higher with 36.4C heat recorded at London's Heathrow Airport.

This makes it the hottest day in August for 17 years.

The Argus:

But the clear skies and sunshine will soon give way to thunderclouds and lightning, the Met Office predicts, with the weather service issuing a yellow weather warning over the entire UK early next week.

Here is the forecast for the next four days:

  • Today

Temperatures will not drop below 22C, climbing to a high of 32C between 3pm and 5pm.

The morning is likely to be cloudy with a 30 per cent chance of rain at noon.

But these clouds will be replaced by clear skies at 3pm, with these conditions lasting until 9pm.

The Argus:

  • Tomorrow

Temperatures will remain high, with thermometres unlikely to dip below 20C.

But the mercury will not quite meet the scorching standards of the day before, peaking at 29C between 1pm and 2pm.

The warmest temperatures, upwards of 25C, can be enjoyed between 10am and 7pm.

There is a slight (30 per cent) chance of rain in the early morning, between6am and 8am, and a brief period of cloud cover between noon and 2pm.

But, aside from this, the day is highly likely to remain dry with clear skies above Sussex.

The Argus:

  • Monday

Temperatures will again reach 29C, at 4pm, but there will be clouds above Brighton throughout the day.

The chance of rain never exceeds ten per cent, the Met Office says, but the weather service has issued a yellow weather warning for thunderstorms across the entire UK.

This spans the full 24 hours of Monday.

A Met Office spokesman said: "Some places are likely to see severe thunderstorms early next week - but there is significant uncertainty in location and timing."

They warned that some areas could see power cuts and sudden flooding as a result.

The Argus:

  • Tuesday

Tuesday, while still warm, will be slightly cooler than the preceding days.

The Met Office predicts highs of 26C between 1pm and 4pm.

There will be sun and cloudy skies throughout, with the greatest chances of rain at 1am (30 per cent) and 1pm (20 per cent).

The yellow weather warning for thunderstorms from the day before remains in place, thought the Met Office reiterated that " there is significant uncertainty in location and timing".
