The great British summer may feel as though it has come to its end this weekend, as frost and fog are forecast for many across the country.
Scattered showers have brought an autumnal feeling over the past few weeks and it is not set to get any better this weekend.
Across the UK tonight, the Met Office forecasts frequent blustery showers, starting in northern Scotland and moving down into northern England and Wales, with occasional showers in the west.
Friday will be cool and breezy, with sunshine and showers, but there will be a risk of thunder too.
Those hoping to have one last hurrah in the sun over the weekend will be sorely disappointed, as heavy showers are likely on Saturday, continuing in the south east on Sunday and Monday.

There's even a warning that night temperatures could drop low enough to see a dusting of frost on the ground in the early mornings.
Patches of frost are likely over high ground in areas sheltered from the biting wind with lows of just 2C predicted for northern parts of Scotland on Saturday night.
There is also the chance of a light covering of snow and sleet showers on higher ground in the north.
The mercury will even remain in single figures in the south during Saturday night.
Conditions will become more settled over the weekend and it will be mostly dry on Sunday.

Forecaster Amy Hodgson, of The Weather Channel, said it would feel chilly before temperatures started to climb again.
She said: "Temperatures in the UK will decrease over the rest of this week, falling 4C below normal across the south-east on Friday, before slowly recovering to near normal next week.
"Maximum temperatures will be in the low to mid teens all this week, in a cold, northerly flow.
"Patches of frost are likely over high ground, with minimum temperatures as low as 2C on Saturday night."
Today, expect blustery showers and even rumbles of thunder.

It will feel very cool for the time of year - especially compared to the same period in 2016 when the mercury was stationed in the high 20s C for much of the country.
Some places will remain dry with sunshine for the weekend, most likely in the north of Scotland and far west of Ireland.
Forecaster Hannah Findley, of The Weather Channel, said low pressure associated with Storm Aileen would be located in the Baltic Sea by Thursday with winds beginning to ease across the UK.
She said: "Wind speeds are forecast to be moderate in the British Isles and across the Northern European Plain, and up to gale force in the Baltic, but generally easing from the west through the day.
"Fronts and troughs associated with this area of low pressure will continue to bring cloud and areas of rain to northern Europe.
"Rainfall totals will be widely moderate, but locally heavy in north-eastern France and southern Germany."
