Meteorologists have predicted that polar vortex, which is splitting into two and swirling southward, will send US and European countries into a chilling deep freeze. A torious swirl of ultracold winds around a low-pressure area due to major stratospheric temperature spike expected to sweep across se countries causing an extreme dip in temperatures. Cana, Eurasia much of Western Europe and US, spine chilling cold winter with heavy sw along US East Coast will ensue, according to several western wear forecasts.
Arctic's polar vortex is a reoccurring winter phemen with strong cold winds that circle westward around pole causing dark frosty winters, Andrea Lang, an atmospheric scientist at University of Albany, explained Mashable. He ded that polar vortex is losing stability and its splitting causes dramatic, extreme wear implications across western nations such as US and Europe. With a ‘disrupted’ polar vortex in 2021, colder air is expected to spill out of Arctic and result in onset of extremely harsh winters, he warned.

ECMWF predicts 'unusually strong ridge'
US Midwest and East Coast witnessed a record cold in 2017 and start of 2018, especially in places like Arctic and Alaska. Global Forecast System (GFS) and European Model, kwn as ECMWF w predict “unusually strong ridge” in middle and upper atmosphere across Alaska in coming one to two weeks. It will swirl coldest winds across rth Pacific and Arctic region. “This can cause jet stream to snap southward, directing frigid air from rrn Cana and possibly even Siberia southward, crossing U.S. border during first week of February,” wear service report mentioned. It also warned that US cities such as Minneapolis, Chicago and New York are expected to go into a deep freeze as chilled winds have dropped temperature in Cana and rrn tier of US such as Upper Midwest and rrn Plains.
