A third asked Channel 4’s weatherman Liam Dutton to identify it, to which he said ‘Looks like asperitas clouds!’

Posting about the clouds, one Twitter user wrote: ‘It’s definitely a sign the UK rejects Trump’.

Another said: ‘I was wondering why it looked like winter’.

The Met Office said: 'Asperitas (formerly referred to as Undulatus Asperitas) is a distinctive, but relatively rare cloud formation that takes the appearance of rippling waves'

The clouds marked the start of the day as thunderstorms and rain battered Britain just days after it basked in the hottest day of the year. 

A band of heavy showers are set to sweep across the country from today, with a yellow weather warning for rain and flooding in place for Northern Ireland. 

Met Office forecasters have warned nights may turn chillier as a system of low pressure makes its way across the UK over the next few days and into the weekend. 

The picture looks set to be in stark contrast to last weekend, when temperatures topped 28C (82F), with Weybourne in Norfolk reaching 28.8C (84F).

Met Office forecaster Richard Miles told MailOnline Britain is set for an ‘unsettled period.’

He said: ‘It is looking wet and showery at the moment, with a heavy band of rain moving northeast today and a risk of thundery showers this afternoon. 

‘Tonight the rain will clear northwards then more showers will move in tomorrow, heavier across south east and central Scotland.   

‘There will be rain everywhere over the next few days with a risk of hail and thunder in south east of England.’ 

What are Asperita clouds and why do they form? 

Asperita, which means ‘rough’ in Latin, is a type of cloud, that has only been officially recognised since 2017.

Formerly known as undulatus asperatus, the formation appears dark and stormlike, but almost always disappear without a storm forming. 

 They are often seen the the middle states of the US, and appear after a storm.

Taking the shape of undulating waves, they usually form at between 4,000 – 10,000 ft.

According to the Met Office, the  way in which asperitas clouds form is somewhat a mystery, and there is debate and confusion about how the foreboding formation comes into existence, as while they often follow storms, sometimes they appear in calm enviroments.

The Met Office website explains: ‘One theory does suggest that they are formed when mammatus clouds descend into areas of the sky where wind direction changes with height causing the wave-like movement.

‘What is clear however is that atmospheric conditions must be unstable to form a wavy cloud base like that seen with asperitas’.
