UK temperatures set to plummet below freezing after mild weekend November 2014 was the joint fourth warmest since records began, with a UK average of 7.7C (46F) But temperatures will plummet this week as cold air from Iceland moves south across the country Temperatures will drop by 10 degrees to as low as minus 2C (28F) overnight in the north tomorrow By Rosie Taylor The country basked in another unseasonably balmy day today with temperatures reaching highs of 13C - but winter will finally arrive in Britain this week as temperatures plunge below freezing. Snow is expected across high ground in Scotland as cold air from Iceland moves south across the country. And the wintery weather is expected to stay throughout December, causing bookmakers to cut the odds on a White Christmas. A tree glows in the red light of the dawn near Great Longstone, Derbyshire, in another unseasonably warm day today North East kite fliers get in the festive spirit as they fly a giant Santa in the clear blue sky above Souter Lighthouse in South Tyneside Deer race across a road near Hassop in Derbyshire today - some parts of the country reached temperatures up to 13C A car is silhouetted against the rising sun this morning in a field near Great Longstone in Derbyshire on another mild day Temperatures will plummet by 10 degrees to as low as minus 2C (28F) overnight in the north tomorrow, as a high pressure front moves in from the north west. It means much of England, Wales, Northern Ireland and southern Scotland will wake up to frost on Wednesday morning and there is likely to be more freezing weather the following night. Met Office forecaster Calum MacColl said the UK would experience a 'shot of cold air' - described by meteorologists as 'polar maritime air' - into the northwest tomorrow from the northern Atlantic. Only parts of the south east and southern coastal areas are expected to escape the frost. He added: 'There is likely to be widespread frost across central England, Scotland and Northern Ireland, but it will possibly be milder in the far south where it will be cloudier. Across north west Scotland we could certainly see some snow at above 400m. High pressure from the north west: Temperatures will plummet by 10 degrees to as low as minus 2C overnight in the north tomorrow Parts of the country woke up to frost today - and chilly conditions will become more frequent as the week continues A dog walker strolls through a foggy Wimbledon Common today - temperatures are set to plummet in the next few days Kite fliers made the most of the pleasant conditions today, but chiller temperatures are forecast for the remainder of the week Two highland cattle are lit in the orange glow of the rising sun in Derbyshire - November 2014 was the joint warmest since records began Alexi Venerus, forecaster at Meteogroup, said: 'There will be frost across the bulk of the country on Tuesday. We may get some wintery showers over high ground in north west Scotland. Through the week overnight there will be places that will get down to zero and the weather will become more unsettled towards the end of the week. It has been milder than normal for this time of year. The weather is probably going to feel a bit more like December with the temperatures on the whole dropping down. The wintery weather will feel starkly different from this year's mild autumn, which was the third warmest since 1910 with an average temperature of 10.8C (51F), 1.4 degrees above the 30-year average. Only autumn 2006 and 2011 have been warmer this century, with average temperatures of 11.4C (53F) and 11.3C (52F) respectively. November 2014 was the joint fourth warmest since records began, with a UK average of 7.7C (46F) making it 1.5 degrees hotter than usual. Bookmakers Ladbrokes have cut their odds on England and Scotland having a White Christmas following this week's forecast. They predict the chance of snow falling on Christmas Day is highest in Scotland, where the odds have fallen from 4/1 to 3/1 in Aberdeen and from 9/2 to 7/2 in Edinburgh and Glasgow. The odds of a White Christmas in London are 5/1, down from 7/1, while Birmingham, Liverpool and Leeds are all at 5/1, down from 6/1. Even in normally temperature Tenerife there has been no escape from winter weather this weekend, as the holiday islands were hit by 80mph winds and heavy rain. Thousands of tourists suffered cancellations and delays to flights and ferry services over fears about the dangerous conditions, according to local reports, and schools in Lanzarote were closed on Friday as the island was battered by storms.
