Thundery snow and hail storms are set to hit parts of Britain tomorrow, forecasters predict.
White Christmas odds were cut as forecasters admitted similarities with 2010, when the Big Freeze began in late November and lasted until New Year.
The Met Office said snow flurries threaten the South, Midlands and North by Wednesday on higher ground, with sleet showers and ice a risk at low levels.
Met Office forecaster Craig Snell said: “It will certainly feel cold, with a big contrast to the past week as easterly winds arrive on Monday from Scandinavia and eastern Europe.
“Snow may fall by Wednesday on the Downs, Chilterns, Peak District and Wolds, with sleet possibly to low levels and the risk of icy patches.
“Thermometers will say 7C or 8C, but easterly winds will make it feel like 4C to 6C, and colder in the East.“-1C to -3C lows at night are possible in the West, with other parts just above freezing.”
Met Office forecaster Steven Keates said: “The remainder of November sees winds from continental Europe most likely, with scope for sleet or snow on higher ground and marked wind chill at times in the South.
“December 1 to 15 is likely to begin cold. There is a small chance Atlantic fronts bring less cold weather in early December, but should it happen, it would likely be short-lived with settled conditions re-establishing with increased frosts.”
