The Record-Breaking Temperature
The UK has recorded its highest-ever May temperature for the second consecutive day, with thermometers hitting 35C (95F) at Heathrow and Kew Gardens in London, the Met Office said.
Previous Records and Weather Warnings
The previous May peak of 32.8C had stood since 1922. The Met Office issued a yellow weather warning for thunderstorms across England earlier on Tuesday, with forecasters warning of isolated storms with lightning, hail, and gusty winds.
Heatwave Threshold and Regional Impacts
Many areas across England and Wales will reach the heatwave threshold on Tuesday, and some will have experienced such conditions for five days by Wednesday, the Met office's senior meteorologist, Becky Mitchell, said. The highest heatwave threshold in the UK at this time of year is 28C, which applies to London and areas north of the capital towards Cambridgeshire.
Health and Safety Concerns
An amber health warning was extended by 24 hours for several regions in England, including the south-west, south-east, London, East and West Midlands, and the west of England. Police reported two deaths over the bank holiday weekend, with a 13-year-old boy dying after getting into difficulty in a West Yorkshire reservoir.
Future Outlook and Climate Context
Temperatures are forecast to start to decline from the middle of the week, but it is still expected to be largely dry with sunny spells. A previous Met Office study found breaking the May record was "around three times more likely now in our current climate than it would have been in a natural climate not impacted by greenhouse gas emissions".
