Britons faced uncomfortable conditions overnight as the heatwave continued to grip parts of the country.

Thursday saw Britain gripped by the second hottest day ever recorded.

But as night drew, a phenomenon known as a "heat burst", caused a spike in temperatures in the evening.

Lincolnshire saw a short and sharp rise in temperatures of 10C in just 20 minutes at around 10.20pm.

Overnight temperatures reached a muggy 32C, while thunder struck other parts if the country.

The sudden rise in overnight temperatures was caused by a collapsed thunderstorm, which quickly forced a blast of hot air down to the surface.

The Met Office graph revealed that heat began rising at Donna Nook, a coastal area in the county, at around 10pm.

The temperature peaked just a few minutes later, before gradually falling again shortly after.

The weather agency also added: "Tonight's event is likely to be an example of a heat burst, a rare atmospheric phenomenon characterised by gusty winds along with a rapid increase in temperature and decrease in dew point (moisture)"

The stifling heat caused travel chaos across the country, with commuters left stranded as trains and roads ground to standstill.
