Texas snow storm: Snownado emerges as polar vortex plunges southern US into winter crisis

BBC Weather: Extreme snow storm forecast for Europe

The footage was taken as the southern US is being pummelled by a winter storm amid deadly lows of -15C. The video shows a large blizzard-like “twister” stretching across the horizon amid violent wintering conditions that have forced President Joe Biden to declare a state of emergency across Texas. Texas Storm Chasers said conditions were becoming “life-threatening” after icy conditions on the roads resulted in more than 100 vehicles smashing into each other in Fort Worth, killing six people.

 

A “Snownado” – also known as a “Snow Devil” – is a very rare weather event believed to be triggered when a cold air front moves across a warmer surface, and a subtle changes in the direction of the wind clashes with air currents forcing raising air to rotate.

Snow on the ground can form steam or fog when warmed by the Sun, it is this low-pressure air that is then sucked up by the vortex and begins to spin, collecting loose snow to form the tornado-like funnel shape.

Meanwhile, the US National Weather Service (NWS) has declared more than 150 million Americans are now living under winter storm warnings.

Alongside Texas other US States such as Kentucky, Mississippi, Alabama and Oklahoma are among states affected by the Arctic weather conditions.

It comes as the latest weather model suggested that Britain could be blasted with its own brutal Atlantic weather system this week.

The latest models from WXCHARTS also show Atlantic air hitting the UK this late on Wednesday and early on Thursday as wintry conditions appear to head over in a westerly direction.

The maps show wintry conditions swirling over the Atlantic and heading for western parts of the UK.

The snow probability chart turns orange in western parts of Scotland, including Ayrshire, suggesting there is between 80 to 90 percent chance of snow hitting from the Atlantic system.

Further east in Edinburgh, Scotland, the chart turns deep blue, which means there could 30 to 40 percent chance of snow on Thursday.

And western parts of England, stretching from Carlise and the Lake District in the north all the way down to Birmingham in the Midlands, show a 10 to 30 percent chance of snow hitting.

The Global Forecast System, a weather model produced by the National Centers for Environmental Prediction, predicts the worst of the weather will turn north just before it hits the UK, reducing the snow’s impact.

Brian Gaze at Weather Outlook warned of the UK being affected by an Atlantic system, although temperatures should be “much higher than in recent days”.

He said: “There will be a very different feel to the weather this week as the flow across the UK comes in from the Atlantic rather than the continent.

“Monday starts mixed across the UK. This morning rain in southern and central regions clears eastwards. Showery rain in the northwest becomes more persistent, but during the afternoon it begins to fade away.

“Elsewhere it will be mainly dry and a few bright spells could develop.

“Temperatures will be much higher than in recent days, ranging from 6C (42F) in the north to 12 (54F) in the south.”
