Plummeting temperatures, sleet and snow will hit the UK next week, bringing a spell of unseasonably mild weather to an end.
Forecasters from the Met Office expect Sunday to be "fine and dry with plenty of sunshine".
A spokesperson added that there is a possibility of "a touch of frost" overnight and occasional strong breezes.
Warm southerly winds will give way to a bitterly cold easterly wind, which will bring the sunshine to an end next week.
Brits should prepare for wintry showers and increased cloudiness by Tuesday and Wednesday.
The forecast predicts that it will feel "much colder than of late".
"There might be sleet and also a bit of snow, over the hills in the north," said Sophie Yeomans, a meteorologist at the Met Office.
"Temperatures will be coming down as the air comes in from the east."
"It will be back to around nine or 10 degrees," she added "so it might be time to dig the scarf and gloves out."
Easterly winds are likely to blow in from across continental Europe throughout the end of November, causing cloudy skies and a sharp wind chill in the south.
Overnight frosts will be widespread by the end of the month and there is a small chance that northerly winds will create even colder conditions.
