The severest of the snowy weather began on 5th January in North West England and west Scotland with temperatures hitting a low of −17.6°C in Greater Manchester, England. The snow spread to Southern England on 6th January and by 7th January the United Kingdom was blanketed in snow, which was captured by NASA's Terra satellite.
The winter weather brought widespread transport disruption, school closures, power failures, the postponement of sporting events and 25 deaths. A low of −22.3°C was recorded in Altnaharra, Scotland on 8 January 2010. Overall it was the coldest winter since 1978-79, with a mean temperature of 1.5°C.
16th December 2009
On 16th December forecasters warned of very heavy snowfall to come. A band of rain moved southwards over the UK, which brought some snow. Snow fell in Kent, Surrey, Sussex and Hampshire, which brought some disruption. Day time temperatures were around 0°C and a low of −7.4°C was recorded in Surrey.
On the 17th, easterly winds brought heavier and persistent snow showers to eastern England and Scotland. Heavy snow showers brought accumulation up to 3 cm in Aberdeenshire, Perth, Kinross and Fife, with some snow showers reaching Glasgow and western parts in the afternoon and evening. In Kent, motorists on the A21 were stuck for several hours during the evening and night.
More heavy snow showers followed on the 18th after heavy overnight snow caused widespread disruption across England in the South East, East Anglia, the East Midlands, Yorkshire and the Humber. Easterly winds brought further snowfalls in both the northern and southern halves of the UK. Overnight, five Eurostar trains were stuck in the Channel Tunnel after cold temperatures caused electrical failures, trapping 2,000 people for 16 hours. Many schools in England were closed. Four Eurostar trains broke down inside the Channel Tunnel, after leaving France, and one in Kent on 18th December. Although the trains had been winterised, the systems had not coped with the conditions. Over 2,000 passengers were stuck inside failed trains inside the tunnel, and over 75,000 had their services disrupted. All Eurostar services were cancelled from Saturday 19th December to Monday 21 December 2009. An independent review, published on 12th February 2010, was critical of the contingency plans in place for assisting passengers stranded by the delays, calling them "insufficient". Snow also disrupted motorways, including the M1, and many airports were closed.

On the 21st some further snow showers affected some parts of the UK with some particularly heavy showers in northern areas. The M25 motorway and large parts of the M3, M23, M4, M40, M1 and M11 motorways were brought to a standstill until late into the night, and many towns were gridlocked. About 100 people were able to travel from London Victoria Station to Ashford International railway station courtesy of a steam train hauled by Tornado. Widespread transportation disruption affected parts of England, Wales, Scotland and Northern Ireland

On the Isle of Lewis, one man died due to the very cold weather. The temperature dropped to −16°C overnight in Dalwhinnie in Cairngorms National Park, Scotland, and it fell to −10°C in Edinburgh.
Fresh overnight snowfall brought renewed problems to other parts of the United Kingdom. In England, north Hampshire and the Thames Valley were particularly badly affected. In Basingstoke, some 3,000 motorists were forced to either abandon their vehicles or sleep in them overnight after becoming stuck in gridlocked traffic. An estimated 2,000 cars were abandoned. The Manchester area had frozen snow which made some dangerous travelling conditions. The AA vehicle recovery service accused some local authorities of not acting quickly enough to grit roads and claimed some "key roads" had "not been gritted at all". The Local Government Association dismissed the claims as "unverified, unsubstantiated and unjustified
In Scotland, overnight temperatures once again dropped to well below freezing, with Dalwhinnie in the central Highlands of Scotland recording a low of −16°C and in Edinburgh −10°C. Large amounts of snow fell in eastern Scotland, with accumulations of up to a foot recorded in the Lothians, Lanarkshire, Edinburgh, Fife and Perth and Kinross.

On Boxing Day drivers in Northern Ireland were warned of icy conditions, but conditions in many other parts of the UK continued to improve as milder air moved in from the south. However, northern England and Scotland remained cold, and night time temperatures continued to drop below freezing. Some Boxing Day sporting fixtures were cancelled or postponed because of continuing icy conditions in places, including the National Hunt meeting at Towcester and all but two of the Scottish Football League's fixtures.

Snow also fell in parts of East Cumbria. In places it was as deep as 10 cms and motorists were warned not to travel unless their journey was absolutely necessary
A weather front carried in the north wind brought heavy snow in the northwest of England. Wythenshawe near Manchester Airport had 13 cms of snow. This affected road transport on 2nd January, particularly in the Greater Manchester area with conditions on the M60, M602 and M66 reported to be poor, while the Snake Pass, which links Manchester with Sheffield, was closed.
In Scotland, a number of roads across the country were closed, including three junctions of the M9, while the motorway was shut in both directions at the Newbridge Roundabout in Edinburgh during the evening because of heavy snow, and did not open again until the following day.

A local record of 48 cms of snow was lying in Aviemore and 3 to 4 feet of snow was recorded within the Cairngorms National Park. Most parts of Scotland had further snowfalls during the night of 4th-5th January.
Due to shortage of road grit conventionally made from rock salt, road grit was being made by or for road-gritters from cooking-type salt mixed with builders' sand, and the public bought up large amounts of cooking salt and table salt from food shops to put on their paths and drives. The Government was reported to have reallocated reserve supplies of road salt and grit from Oxfordshire and Buckinghamshire and sent it to Cumbria and Fife due to the higher priority of even lower salt and grit reserves, along with the greater snow clearance work, according to Radio Oxford.
The synoptic situation in northern Europe settled to a steady northeast wind which brought snow showers and belts of snow. The British Army had to help stranded motorists in southern areas. The Met Office confirmed that 40 cms of snow fell in some parts of southern England. A severe warning issued by the Met Office was in place for every region in the UK.
