The Met Office has issued a yellow weather warning for heavy rain in parts of Suffolk and Essex.
It's valid until 5pm on Bank Holiday Monday.
The Met Offices says further areas of heavy rain or thundery showers are likely to affect parts of southeastern England and East Anglia at times on Bank Holiday Monday.
The main risk periods would seem to be before dawn and again during the middle of the day and into the afternoon. The evening should see a slow transition to drier conditions from the west.
"Parts of East Anglia and southeast England will still be affected by a warm, humid and unstable airmass during much of Monday, which leaves the opportunity for thundery downpours to spread from Northern France.
As in many such cases, only a minority of places will see the heaviest rain, but there is a chance that some locations could see 20 to 25 mm of rain in an hour and perhaps 40 mm in a few hours."
In the final part in his series Clearing the Air, ITV Anglia weatherman Aidan McGivern has been taking a look at fog.
He's been to Bedfordshire to talk to scientists involved in the latest research on what causes fog and how it can be predicted more accurately.

And here are ten facts about fog from Aidan
- The difference between mist and fog is how far it is possible to see. The airline industry define fog as visibility less than 1000 metres. The civilian definition of fog is when visibility is less than 200 metres.
- When fog occurs and the temperature is below 0ºC, it is called freezing fog.
- Rime occurs when the water droplets in fog freeze onto the outer surfaces of objects, giving everything a frosted covering.
- Smog is a type of air pollution made up of smoky pollution and fog. The worst smog to ever hit the UK was the Great Smog of 1952, which wreaked havoc for four days in London. This led to the Clean Air Act of 1956.
- Vog occurs when volcanic gases such as sulphur dioxide react with oxygen and moisture in the atmosphere under direct sunlight to give a volcanic fog. It is common in Hawaii.
- Fog is simply another type of cloud: a stratus cloud that sits on the ground
- The foggiest place in the world is the Grand Banks off the island of Newfoundland where the cold Labrador current from the north meets the warm Gulf Stream from the south. The water vapour that accompanies the Gulf Stream cools quickly and condenses, forming fog.
- In the Atacama Desert in Chile, one of the driest places on Earth, fog is harvested from the air - using mesh-patterned nets to collect its water droplets.
- The Fogstand Beetle in the Namib Desert stand still in the fog and allow the water droplets to condense onto their body, which they then drink.
- Titan, Saturn’s largest moon, is the only object other than Earth in the Solar System known to have plenty of liquid on its surface. It is also the only other object to have patches of fog, albeit fog made up of methane and ethane.
There was damage to at least one home at Winfarthing near Diss today.
One family came home to find what they believe may have been a mini tornado had struck their home.
As well as high winds in places there was also some torrential downpours.
Drains were overflowing, cars were struggling and passers by were getting absolutely drenched.
A brief blast of heat from the south will push temperatures to 30ºC in places this Saturday before it all ends in thunderstorms.Read the full story ›
In the latest in his series Clearing the Air, ITV Anglia weatherman Aidan McGivern has been taking a close look at clouds.
He's even been flying fifty feet above the North Sea - in a bid to explain how clouds are formed.
"Even in the middle of summer, clouds are a familiar sight in the skies above the UK. But the tiny particles that cause clouds to grow and decay are much more difficult to observe. In fact, the best way to study them is to take to the skies and journey to the heart of the clouds."
Cranfield Airport in Bedfordshire is the home for the Facility for Airborne Atmospheric Measurements (FAAM).
Using one of the most advanced research aircrafts in the world, Scientists from the Met Office and the Natural Environment Research Council study everything from the physics of the clouds to the chemistry of the sky.
In July, Aidan took to the skies with atmospheric scientists from across the UK for an instrument test flight ahead of a research mission to the tropics.
This summer, they are investigating the moment when water droplets in clouds freeze and how this impacts the development of the cloud.
Ten facts about clouds
Other planets in our Solar System have clouds. The clouds on Venus are made of sulphur dioxide whilst Jupiter and Saturn have clouds of ammonia.
In 1803, Luke Howard used Latin words to classify the clouds into nine main types. These included cirrus \(wisps\), stratus \(a layer\) and cumulus \(a heap\).
The average thickness of a cloud droplet is 0.02mm in diameter. This is around five times smaller than the thickness of a sheet of paper.
The sunniest city in the world is officially Yuma in Arizona with over 4000 hours of sunshine each year, which amounts to around 91% of the time.
The cloudiest parts of the world are found close to the poles and the cloudiest city on the planet is thought to be Chengdu in China, which has just 1,100 hours of sunshine each year.
Clouds are good omens in Iran. They have a saying for when someone is blessed with good luck: “dayem semakum ghaim”. This translates as "your sky is always filled with clouds"
Clouds are very heavy. A small cumulus cloud might typically weigh as much as two elephants.
In 1959 Lieutenant\-Colonel William Rankin, a pilot in the US Air Force, was ejected from his plane and into a cumulonimbus thunderstorm cloud. He spent half an hour trapped in the cloud, thrown around by the up and downdrafts and pelted with hail. Amazingly, he survived the ordeal.
Most clouds form in the lower part of the atmosphere called the Troposphere. Occasionally, clouds can form in the Stratosphere, which is the layer above the Troposphere. These are called Nacreous clouds.
Only 1% of rain outside of the tropics comes from ice-free clouds.
Yellow and amber warnings are in force for heavy rain as thunderstorms approach the East of England from the near continent this evening.
The amber warning is in force until 21:00 this evening and covers southern parts of Essex and the south East of England.
The Met Office Chief Meteorologist warns:
Another pulse of thundery activity from France will extend across the area this afternoon and evening. The ground remains saturated from earlier heavy rain, and the high water loading in the atmosphere means that more than 30 mm in an hour or less could well occur locally.
Elsewhere, a yellow warning is in force until late Friday because of the risk of further heavy rain overnight and into Friday afternoon:
Localised thunderstorms may also develop across south east England and East Anglia during Friday late afternoon and evening, these potentially giving 15-25 mm of rain in an hour.
The environment agency are also urging people to be careful not to drive through floodwater and for campers and holidaymakers to check the flood risk for their area.
Heavy rainfall this afternoon and into this evening brings risk of further surface water flooding, particularly for parts of Essex. If you’re driving away or back from your summer holidays, as always, please remember not to drive through flood water. People are urged to check their flood risk on our website, especially if you’re holidaying in an area where you’re not familiar with the flood risk.
How exactly do we know what causes fog to form, which clouds will give us rain, or how polluted the air outside is? Well, our weather presenter Aidan McGivern has been out and about this summer meeting the scientists who turn their eyes to the skies and research the state of the atmosphere. His first stop was at Weybourne in Norfolk - an unlikely site for research into global pollution levels.
But not many people will know about the observatory there on the North Norfolk coast and the work it does to monitor global air pollution levels.
So here are another 10 facts about pollution that you may also not be aware about.
- Since the Clean Air Act in 1968, air pollution in the UK has decreased - especially sulphur dioxide and smoke.
- However, some urban areas in the UK are still highly polluted - a 2012 study estimated that 19,000 people each year die from the effects of air pollution.
- Another study suggested that walking in Oxford on an average day was the equivalent of smoking sixty cigarettes.
- Air pollution from road vehicles is most harmful to human health.
- The worst pollutants in the UK are ozone, particulate matter and sulphur dioxide.
- The Department for Environment, Food and Rural Affairs have created a daily warning system to inform people of expected pollution levels.
- There are 500 million cars in the world at the moment and by 2030 there are expected to be one billion cars.
- People most at risk of high pollution levels are children, the elderly and those with heart and lung disease.
- China is the world's largest producer of Carbon Dioxide.
- The great smog of 1952 in London lasted for four days and is regarded as the worst pollution disaster the UK has ever known.
Ever wanted to know more about the science behind our skies? Well ITV News Anglia's weather presenter Aidan McGivern has been looking into it as part of a new series of reports called 'Clearing the air'.
He's been looking at how fog forms, which clouds will give us rain, and how polluted the air outside is - and he's been finding out about it by meeting the scientists who turn their eyes to the skies and research the state of the atmosphere.
His first stop is at Weybourne - an unlikely site for research into global pollution levels.
