- Temperatures will hold up at up to 15C (59F) until Saturday, then drop to highs of 9C (48F) from Sunday
- Mercury is currently two degrees above average for time of year with 15.8C (60.4F) highs yesterday
- But there will be noticeable change from second half of the weekend amid return of overnight frosts
Britain is set for another mild week with temperatures holding at up to 15C (59F) until at least Saturday – before a plunge in conditions from Sunday sees the mercury struggle to get into double figures next week.
The mercury is currently around two degrees above average for the time of year, but there will be a noticeable change from the second half of the weekend amid the return of overnight frosts and a chance of sleet or snow.
Highs of 9C (48F) are expected onwards from Sunday with temperatures dropping below zero at night, just days before the official start of meteorological winter in just over a fortnight’s time on December 1.
It comes after a warm and pleasant end to the weekend for many parts of the UK yesterday, with a high of 15.8C (60.4F) at Altnaharra in the Highlands. The record for November 14 is 17.8C (64F) set in both 1938 and 1948.
Temperatures will be a little lower today with weakening frontal systems sinking slowly southwards. There will be morning fog in the South East, rain across Wales and northern England and sunny spells in the North West.
Tonight will bring clear spells for parts of the country but generally a cloudy and foggy night for most. There will also be scattered showers across central Wales, the Midlands and parts of the North East of England.
A weak front will linger across England tomorrow while a cold front brings chilly conditions to the north. It will be cloudy for many areas with some heavy rain in the North, which will be followed by blustery showers later on.
Wednesday will then be a cooler day with showers in the North, these wintry over Scottish mountains at first. By Thursday a warm front will bring rain to the West and North West, while it will be drier and milder in the East.
On Friday, high pressure will build across the South, holding a cold front at bay in the North. It will be rather cloudy in the South, but dry for many areas – and breezy with spells of rain in the North.
Looking ahead to the weekend and beyond, BBC Weather meteorologist Alina Jenkins said: ‘As we head through the weekend and into next week, initially we see some frontal systems pushing their way across bringing some wetter and windier weather, but also the changing wind direction to something more northerly and high pressure starting to build back in.
She added that it would be ‘wetter on Saturday and then behind that things will turn colder, there will be some spells of sunshine, it will be dry but we’re likely to see a return to overnight frosts’.
The Met Office said in its forecast for this Friday until the end of the month that there was a ‘possibility of a trend towards colder conditions later, with a low risk of wintry showers in the north’, with frost likely overnight.
It said: ‘Cloudy for most, with patchy, mainly light rain across the far north. Throughout this period, winds will often be blowing from the west or northwest, with some incursions of northerly winds possible.
‘High pressure will often be close by to the south and southwest of the UK, bringing largely settled and dry conditions here, this possibly extending to all areas of the country at times.
‘However, some spells of rain are likely to affect northern areas, accompanied by brisk winds. There is a possibility of a trend towards colder conditions later, with a low risk of wintry showers in the north.
‘Otherwise, temperatures are likely to be close to or just below average. Under high pressure, frost and fog is likely overnight, this fog slow to clear during the morning.’
