In typical British style, rain will play a major part during King Charles' Coronation as the historic event finally arrives.
Charles and Queen Camilla will be enthroned in a ceremony which will take place at Westminster Abbey on Saturday morning, with more than 2,200 people in attendance.
Thunderstorms hit London on Friday and steady rain is forecast for Saturday by the Met Office but Charles remained upbeat about the weather when he spoke to well-wishers on The Mall on Friday.
He told a group of campers: "I hope you don’t all get soaked. Rain is a blessing... except for your camera!"
However, the wet weather will follow some sort of recent tradition as it will be the third Coronation in a row that is affected by rain.
Met Office meteorologist Alex Deakin said: "It will be a very damp start to the weekend in the southwest and this rain doesn't stop here.
"It will trickle into South Wales, parts of the Midlands and yes, on and off in the London area from mid-morning onwards. Not particularly heavy, but a fairly dank day."
The rain will move northwards through the afternoon, while Northern Ireland and Scotland should be drier with bright spells although heavy showers may break out.
Despite the wet conditions, the UK will feel "reasonably warm" with temperatures in the mid-to-high teens. London could reach highs of 17C, with Fort William in western Scotland peaking at 18C.
The English capital should be dry as we head into the evening with the rain working its way further north and could fizzle out completely by Sunday morning.
Mr Deakin added: "Many other places will become dry overnight, and Sunday overall promises to be drier and brighter weather for many.
"But we'll still have some clouds grazing the coast of Aberdeenshire and Northern Isles and we will still see some showers breaking out during the day, particularly across the eastern parts of England, where they could again be on the heavy side."
On Sunday, the celebrations continue in London as a special Coronation Concert will be held in the grounds of Windsor Castle but the artists could get caught up in more rain when it starts at 8pm.
The mercury is set to rise higher than Saturday, with much of the country ranging between 16C and 19C. London should reach the higher mark during the afternoon but a weather front will work its way across, bringing more cloud and wet weather.
