The big chill is set to tighten its grip over the weekend as forecasters say we could be on for the coldest February in nearly a quarter of a century.

Temperatures in the first two weeks of the month averaged just 2.1c (35.8f) - meaning Britain has been far colder than Vancouver, where the organisers of the Winter Olympics have been forced to truck in snow.

The freezing conditions will continue over the weekend with some areas experiencing overnight lows of -6c (21f).

The latest blast of wintry weather led to problems for travellers today, with forecasters predicting further snow over the weekend.

Birmingham Airport's runway, shut overnight due to the snow, reopened at 6am today but passengers endured delays and cancellations.

A series of accidents led to road and lane closures on some major routes, while power supply problems caused delays to rail services in the West Midlands and the Liverpool area.

The problems at Birmingham Airport were caused by snow which extended to many parts of the UK, especially Wales and central England where some parts saw several inches settle.

A Birmingham Airport spokesman said several aircraft were currently being 'repositioned' there after being diverted away from the city when the runway closed last night.

On the roads, a jack-knifed lorry caused a section of the M40 in Warwickshire to be closed, while an accident also shut a section of the M62 in Greater Manchester.

Accidents also affected traffic on the M5 in Worcestershire, the A14 in Cambridgeshire, the M55 in Lancashire and the M62 in West Yorkshire.

To add to travel problems in the West Midlands, an overhead wire problem in the Sutton Coldfield area meant the London Midland train company had to replace trains with buses between Lichfield Trent Valley and Wylde Green.

An electrical supply problem at Ainsdale in Merseyside led to delays to services run by the Merseyrail train company.

Matt Dobson, of MeteoGroup, the Press Association's weather company, said the rest of today would see a mixture of sunny spells and scattered wintry showers.

He went on: 'It's going to continue to be cold, especially at night, when there are likely to be quite severe frosts with temperatures down as low as minus 6C (21F).

'There could be bands of wintry showers across the country tomorrow, while on Sunday there is the risk of a heavy area of snow from Wales into the Midlands. This could produce a couple of inches of snow in some areas.'

The Met Office said if temperatures fail to pick up towards the end of the month, it will be the coldest February since 1996, when temperatures averaged 2c (36f).

But a slight drop in average temperatures would leave us with the chilliest February since 1986, when the average was -1.2c (30f).

Met Office forecaster Barry Gromett said: 'It is not going to warm up significantly over the next few days.

'Snow will continue into the weekend on the north-eastern and north-western coasts of Scotland.

'Daytime temperatures will recover over the weekend in much of the country. It will be around 6c (45f) in the South and 4c (39f) in the North. But there will still be widespread frosts overnight this weekend with temperatures as low as -6c (21f) in the North and -3c (27f) in the South.'

The Met Office has issued a weather warning of a 60 per cent chance of heavy snow affecting the whole country north of the Thames Valley on Monday.

Yesterday, the snowfall began in south Wales at around breakfast time and spread over large areas of central England during the morning and afternoon.

'It is coming down fairly heavily in places, with accumulations to a depth of two inches,' said John Hutchinson, a forecaster with MeteoGroup, the weather division of the Press Association.

The falls were triggered by moist air from the Atlantic meeting cold air already over the country.

From south Wales the snow spread to the Bristol area and other parts of the West Country, then to the Midlands, including Rugby and Leicester.

The snow followed a bitterly cold night in many areas with temperatures falling to minus 16c at Braemar in Scotland, minus 5c in East Anglia and 0c in London.

Meanwhile in Vancouver - the one place where snow would be welcome - the Canadian city is basking in temperatures have rarely sunk below 7c in recent days.

It is the first city at sea level to host the Winter Olympics and also the warmest to do so.

The men's downhill skiing had to be postponed by two days because of slushy conditions on the course and Olympic organisers have had to transport snow to some sites.

Mr Gromett said: 'Daytime temperatures in Vancouver this week have been as high as 13c.

'At one of the Winter Olympics venues, Whistler, temperatures have been as high as 7c during the day.

'Meanwhile, daytime temperatures in the Midlands here have been barely above freezing at 1c or 2c.

'If it stays as cold as it was in the first two weeks for the rest of the month, it would be the coldest February since 1996 and may be the coldest since 1986.'

Last month was the coldest January in Britain for 23 years.

Earlier this month, heavy snowfalls and ice resulted in widespread disruption. The South East saw the worst of it with up to six inches of snow in parts of Kent, where more than 200 schools and nurseries were closed.
