Mark Vogan has issued his winter forecast,
UK TO FACE 3RD STRAIGHT WINTER WITH PERIODS OF HEAVY, CRIPPLING SNOW AND SEVERE COLD, WORST OF WINTER CONTINENTWIDE TO BE CENTRED OVER SCANDINAVIA
DECEMBER
PERIOD BETWEEN DECEMBER 15-20TH HERALDS THE ONSET OF INCREASINGLY WIDESPREAD SNOWFALL AND COLDER WEATHER FROM OFF THE CONTINENT
JANUARY
The tough later part of December will set the stage for what may be a severe first 10 to 15 days of January as a strong NEGATIVE NAO (North Atlantic Oscillation & AO (Arctic Oscillation) firmly establishes itself with deep troughs filled with increasingly bitter Arctic air centred from the UK eastwards to Germany.
FEBRUARY & MARCH
I believe, though the worst of winter's cold and snow will be behind us come mid-January, return blasts of snow followed by cold is highly possible, similar to what we encountered back in February and March of 2011.
