Longer term weather models show the infamous La Nina will be triggered this year bringing plummeting temperatures to the Eastern seaboard and Great Lakes region.
And the effects of La Nina will be massively strengthened by both the so-called Pacific Decadal Oscillation and the Alberta Low which both cause dramatic falls in temperature.
The PDO is a huge ocean system similar to the El Nino which operates over a time scale of decades and brings either cooler or warmer weather to mainland and eastern USA. For the winter of 2017/2018 the PDO will bring colder weather.
Perhaps more dramatically the Alberta Low will work with La Nina to trigger an unstoppable climate chain reaction bringing colder and colder temperatures.
Analytical meteorologist Tyler Sotock suggested America was facing Snowmaggedon.
And spokesman for another YouTube weather channel Hurricane and Winter Tracker warned of.
He said: “ With regard to Alberta, once a cold shot comes through the Great Lakes start to get active and you get snow.
“If you have a low pressure system coming through and it travels out to sea what you have is a fresh batch of deepening really cold air and the air gets colder than it was before which in turn enhances the snows so we get snows dumping all over these regions over and over again.
“That’s going to be a real hazard with snow banks 10 to 15 feet high.”
Meteorologist Mr Sotock pointed out the US had experienced the coolest summer since the Snowmageddon of 2009 and warned that huge storms could join the mega-snows of the 2017/2018 winter.
He said the El Nina was basically a “weak El Nino” and added: “When you have a weak E Nino you get snows on the East Coast wetter weather on the south east energising the jet stream which causes big storms especially in the mid-Atlantic and East Coast.”
Even the legendary Farmer’s Almanac, which has been weather forecasting since 1792, is predicting temperatures on a par with last year’s super-winter but with even more rain.
