Pack away your barbecues and get your winter woolies on standby – most of Britain is set to be hit with dreary weather this Bank Holiday Weekend.
While Western parts of the UK will enjoy the best of the rather bleak weather, in keeping with the finest of British traditions; much of the country will be wet.
In what could put a dampener on this year's Notting Hill Carnival, experts have said London, the South East and East Anglia are likely to be hit with heavy rain over Saturday and Sunday – so be sure to pack a brolly.
The Met Office today issued a severe weather warning for much of the country tomorrow, with the south east, midlands and north east set to be worst hit.
"Outbreaks of rain affecting parts of England and north east Wales during Saturday are likely to be heavy in places, with the risk of torrential thundery downpours, lightning and local accumulations in excess of 40 mm within just a few hours," a statement read.
"The highest probability of heavy rain is considered to be towards the east and southeast of England.
"The public should be aware of possible localised surface water flooding where this occurs, as well as some disruption in general to summer outdoor activities."
Those looking for sunshine in a desperate last ditch attempt to top up their tan before winter sets in should go west, experts have advised.
Matt Dobson, a forecaster for MeteoGroup said: "It's really an east-west split in the weather on Saturday, where west is definitely best.
"In England, Wales and Scotland there will be sunny spells and generally dry weather in western areas, whereas in eastern areas it will be cloudy with outbreaks of rain."
The forecaster said the warmest places will be from Devon and Cornwall, through Herefordshire, Worcestershire and Wales, and up into Cumbria and the western half of Scotland. Temperatures will reach highs of 20C (68F) or 21C (70F).
"It's not looking brilliant for the South East on Sunday," Mr Dobson said.
"It's going to be wet and cloudy with a north easterly wind with further showers or heavier spells of rain."
Across to the west there will be sunshine again, with highs of 22C (72F) in some parts.
However, the expert said most of the country should be dry on Bank Holiday Monday.
"This is probably going to be the driest day for the whole weekend," he said.
"Much of the country, including the South East, is going to get away with better weather.
"The South West, Wales and Cumbria will be the best places."
Meanwhile, in an attempt to make the most of the hot and sunny weather in the South East of England, more than six million Britons are set to make overnight-stay trips at home and abroad over the weekend.
Around 4.5 million people are planning to take holidays involving an overnight stay in the UK, while a further 1.8 million will be heading overseas at the weekend, according to travel organisation Abta.
