The weather front will reach the country on Wednesday, bringing snow and heavy showers to most of the south-west of England, Wales and parts of Northern Ireland. It will then move northwards throughout the day, reaching the Midlands and parts of northern England and south Scotland. BBC Weather forecaster Carol Kirkwood warned: “Through this evening and overnight high pressure will kill a lot of the showers and with clear skies, it’s going to be a widely cold night, colder than the night that is just gone. There will be some frost, the risk of ice and this is what we can expect in towns and cities.
“In rural areas, it will be lower than this.
“But through the night, in the south-west and across Wales, clouds and some rain will come in.
“That’s that area of low pressure bringing rain steadily from the south-west pushing northwards through the day.
“So we start off with lots of sunshine in many parts of the north and the east.
“But through the day, the rain advances and this rain could fringe into southern Scotland as it moves through Northern Ireland, northern England, Wales and the Midlands down towards the south-east.
“Through the evening and overnight we still have this area of low pressure, still producing some hill snow and then it will continue to move away towards the south-east.”
Net Weather forecaster Paul Michaelwaite also warned the cold air will lead to snow showers. He said: “Usually, at this time of year, we start to see the jet weakening and moving North.
“Still, although it’ll happen at some point, it’s not looking too likely in the short to medium term, with the unsettled, often cool weather expected to continue for a while yet.
“For today though, a shallow low has moved over southern England overnight, with the last of the rain (with some sleetiness over the hills) slowly clearing southeast this morning.
“Apart from that, it’s a day of sunny spells and showers, with the most frequent ones likely in the North and west. Some of the showers will be wintry as well, with rain, hail, sleet and snow in the mix.
“Temperatures will be tempered by the fresh westerly wind (in fact it’ll touch gale force in the far northwest of Scotland), with highs on the thermometer of 4-8c in England and Wales, 3-6c in Scotland.
“This evening and overnight, a more organised band of showers will move southeast from the northwest of Scotland, making it into Northwest England by dawn.
“Elsewhere it’ll be mainly dry with clear spells allowing for a touch of frost, and the risk of some icy patches.”
Mr Michaelwaite added a new Atlantic system will arrive as the week develops.
This will result in more snow as well as torrential downpours and powerful winds.
He said: “Tuesday follows on with the sunshine and showers theme. It’ll be a touch milder across the southern half of the country, with highs getting into double figures in the south of England.
“It stays chilly enough for the showers to be wintry from north Wales northward though, with more snow up over the high ground.

“The showers in the day will die back to the coasts in the evening, with a widespread frost forming.
“Cloud will thicken from the southwest later in the night though, ahead of an Atlantic system, which will eventually bring some wet weather up from the southwest with it.
“That’ll move northeast during Wednesday, bringing some generally patchy rain to most of England and Wales, although the far North by stay clear of it.
“To the North of that, it’ll be another cold feeling day with sunshine and showers.
“Into the latter part of the week, there’s no dramatic change. The weather stays cool, with showers along with the odd longer spell of rain at times.
“There’ll be the risk of some frost and ice overnight, and the showers will sometimes be wintry – especially over the high ground and in northern Britain.“
