The UK is currently basking in balmy conditions with temperatures forecast to hit a boiling 30C today in what could be the warmest start to May on record. Following a surge of warmth on Tuesday that brought temperatures close to 25C in parts of England, the unseasonably hot spell will continue today.

The Met Office has a specific criterion for what constitutes a heatwave: three successive days with temperatures going beyond the "heatwave threshold", which varies by region but generally starts at 25C in much of the UK. WXCHARTS weather maps have turned a blistering red for today, indicating boiling temperatures.

However, sun-loving Brits will be disappointed to hear that in a matter of days, the mercury will nosedive with some areas predicted to wake up to a chilly 0 °c temperatures, according to WXCHRTS weather maps.

The Met Office agrees with this, with the forecaster warning it will become "rather cool in places".

Brits waking up on Sunday morning may want to put on an extra layer. Scotland, the North East and North West are likely to experience the most brutal weather conditions with the mercury around an icy 0C-2C at 6am.

Showers are likely for areas along the coast in the North and East. Likewise, the majority of Wales are predicted temperatures of 1C- 2C.

Yorkshire and the Humber, as well as the East Midlands, will see slightly higher temperatures of 3C.

London and the South East are likely to see the warmest temperatures of around 5C but this is still a remarkable drop from the 30C forecast today. Showers are also forecast for the south putting a possible dampener on Brits bank holiday plans.

The weather on Saturday is not expected to be relatively warm with Scotland to see the mercury hover between 3C-4C. Whilst London and the South East will see the highest temperatures of a modest 9C.

Separately, in the Met Office's weather outlook for the weekend, the forecaster said: "Scattered showers in the south at times, and a few further north, though a lot of dry weather for many with some sunshine.

"Temperatures dropping, becoming rather cool in places."
