Met Office issues a snow warning as an 80mph jetstreak threatens to cause havoc — 7cm of snow in HOURS.

THE UK is bracing for an onslaught of bad weather as an 80mph freezing “jetstreak” slams across the country, dumping heavy snow in a matter of hours.

On Saturday, the designated Storm Arwen, and issued an amber weather warning for northeast Scotland and England, in addition to yellow warnings for Scotland, Northern Ireland, the west of England and Wales, and much of the UK. A furious “jetstreak” – a zone of stronger conditions within a jetstream – is sweeping through Greenland, bringing with it a massive area of low pressure that will bring “quite exciting weather” to the UK on Friday and Saturday. On Saturday, Met Office meteorologist Alex Deakin warned that 80mph gale-force winds could hit parts of the UK, with rain falling “almost anywhere from the Midlands northwards.”

Storm Arwen is expected to deliver snow to higher area in Scotland and Northern Ireland, according to the forecaster’s latest update, and a yellow snow warning is in effect for parts of Scotland on Friday.

Later on Friday and into Saturday, sleet and snow are predicted over some lower areas in the UK.

WXCHARTS’ newest weather maps indicate up to 7cm of snow falling in a region of North East Scotland on Friday evening, with some precipitation expected in North East England as well.

On Saturday, the snow begins to fall more widely across England, with up to 7cm falling just north of Newcastle and up to 3cm in surrounding areas, as well as some snow in parts of North West England.

“This jetstreak drives an area of low pressure, with this arching position of the jet making it into a violent feature – isobars springing out and strengthening because of its contact with the jetstream,” said Met Office meteorologist Mr Deakin.

“That low will bring a lot of action to the weather on Friday and Saturday.”

“At first, these weather fronts will bring rainy and windy weather as they drop southward, but watch the squeeze in the isobars on Friday evening across northern Britain as the low drives along the north sea.”

“On Saturday, there will be a lot of isobars covering the country, resulting in some really strong winds throughout all places for a period of time.”

“On Saturday, a larger area including the majority of the United Kingdom was issued yellow warnings for wind gusts of 50-60 mph. “Brinkwire Summary News” on the coastlines of the North East.
