A yellow weather warning has been issued by the Met Office for ice
Following a weekend gripped by the coldest temperatures of 2017, the freeze is expected to loosen its hold on Wednesday.
But a severe yellow weather warning will continue until 11am across most of England, Wales and Scotland, as remaining ice threatens treacherous conditions on roads and paths.
The coldest temperature of the last five days - in Shawbury in Shropshire - was a low of -13C, with the mercury in Powys falling to -10.1C and in Loch Ness -9.1C.

Many areas enjoyed a blanket of snow thick enough for sledging and snowmen - in Sennybridge, Wales, 30cm of the white stuff was recorded, while High Wycombe saw 18cm fall.
Across the country, that had a knock-on effect for hundreds of schools which were forced to close.
Severe weather warnings were in place into Tuesday, and icy roads and compacted snow led to concerns of treacherous conditions.

The freeze also coincided with the beginning of cold weather protocol for homeless charities, and cold weather shelters in the UK opened their doors to people sleeping on the streets.
Disruptions also grounded flights and caused delays to and from airports including Birmingham, Manchester and Edinburgh. British Airways cancelled 170 flights on Sunday and more than 100 on Monday.

Meanwhile, rail disruptions caused travel chaos, with cancellations between Birmingham and Bristol after a landslide caused by the severe weather.
The Port of Calais was also closed, after a ferry carrying 300 people ran aground as it attempted to depart for Dover in a storm.
The lowest daily temperature ever recorded in the UK was -27.2C, registered in 1982, 1985 and 1995 in Braemar and Altnaharra in Scotland.
Comment: The UK is infamous for it's inability to deal with cold weather and with winter only just beginning it's not a good sign what with predictions, and signs we can see all around the world, that we're entering an ice age. This unusual weather is blamed on a 'polar vortex', where the jet stream in the north pole descends further south bringing with it extremely frigid air. And with each year it seems to be behaving more erratically, meandering further south and with an ever increasing regularity. It's effects are being felt all over the northern hemisphere (though the same is happening in the southern hemisphere too) where winters begin more abruply and are much more intense than before.

This is all probably related to our sun which is slowing down and causing other unusual weather phenomena on Earth. And it's not just Earth that these changes are being documented, it's happening through the solar system.For more information see Pierre Lescaudron and Laura Knight-Jadczyk's book: Earth Changes and the Human-Cosmic connection.
