NASHVILLE, Tenn. (AP) – A winter storm that brought a rare white Christmas to parts of the South barreled up the East Coast on Saturday night, with forecasters predicting 6 to 10 inches of snow Sunday for Washington and blizzard conditions for New York City and the New Jersey shore.
The pattern has been consistent across the northern hemisphere, as the Met Office image above confirms.
From the Daily Mail:
A Met Office spokesman: ‘The problem is we are not getting the warmer Atlantic air that normally keeps our winters mild.’
‘We can see that it is unseasonably warm over Canada and Greenland, this is where warm air has been diverted.’
He said that any change in the pressure over the Atlantic would need to last for several days before we would notice any change in the weather in Europe.
Freezing-cold winters and milder winters tend to cluster in groups, as the jet stream changes its path.
Experts are still unsure why this is but suspect it may be related to the EL Nino weather system as well as changes in sea temperatures and solar activity.
