Winter will come early to Britain next week as snow is forecast for the north while the south will shiver in frosty sub-zero nights.
The cold snap will seem worse after temperatures soared to 75F (23C) last weekend.
Forecasters warned snow is due in Scotland and possibly northern England next week, with frost as far south as southern England, which will see bitter 48F (9C) daytime maximum temperatures.
Sir Stuart Rose reveals his secret at Sir David Frost's summer party“A northerly air stream in the middle part of next week means coldest conditions will probably be in Scotland, with sleet or snow showers and snow settling on higher ground,” said forecaster Brian Gaze of independent forecasters The Weather Outlook.
“Even southern England will feel distinctly chilly."
Forecasters Positive Weather Solutions have already predicted a ‘white-out’ winter almost as harsh as last winter - with widespread snow, temperatures down to -4F (-20C) and transport chaos.
The Weather Outlook, which has an accurate seasonal forecasting record, warned the UK is now being gripped by a bitter series of winters comparable with the harsh 1939-42 winters which made conditions so horrendous during the Second World War.
Last winter was the coldest for 31 years, with an average UK-wide temperature of just 34F (1.5C).
“Winters were mostly milder than average from 1991 to 2007, but this changed with a colder winter in 2008-09 and last winter being the worst since 1978-79,” Mr Gaze said.
“History shows cold winters do tend to come in clusters, indicating underlying factors cause them to persist for a number of years.
The heaviest snowfall occurs on the boundary between cold, dry air from the east and mild, moist air from the Atlantic - so it would not be a surprise to see the west of the UK having heavy snowfalls
