Outlook for the UK over the next 6-30 days

UK Outlook for Tuesday 23 Dec 2014 to Thursday 1 Jan 2015:

Rain over central and southern parts Tuesday should move slowing southeastwards, clearing the southeast early on Christmas Eve. Colder showery conditions to the north, with snow on high ground here, following over the entire UK. The colder conditions then persist for most through Christmas Day and the following weekend with snow even to low levels at times in the north. There is a low probability of some more persistent rain crossing southern parts during the holiday weekend with a risk of snow on the leading edge. Otherwise in the following week there looks to be a gradual return to spells of wet and milder weather interspersed with colder, showery conditions. Generally windy for many throughout the period with risk of gales, these mainly in the northwest.

UK Outlook for Friday 2 Jan 2015 to Friday 16 Jan 2015:

The most likely scenario for the coming New Year is for a continuation of changeable, and at times windy weather coming from the Atlantic with the wettest weather probably across western parts of the UK, and eastern parts most likely to see the best of any dry weather. In between the wetter periods there should be drier, brighter, and colder spells. Temperatures are most likely to be around or slightly below average for the time of year with overnight frosts and some snow over the high ground expected. There is a chance of some overnight and morning fog in places too. However, there is a low likelihood that the drier spells will become more prolonged between weather systems.

Cardiff information

Cardiff was named capital city of Wales in 1955 and with population of around 350,000, Cardiff is the 10th largest UK city.

The city has a long and varied history, with evidence suggesting the existence of settlers in the area around 1,500 years before the building of Stonehenge. Cardiff's easy access to the coal fields of South Wales has played a large part in its history and demand for coal, used for manufacturing iron and steel, led to Cardiff becoming the world's largest coal port. Since then, the economy of Cardiff has diversified into a range of industries. Cardiff is now the largest media centre outside of London and is the home of BBC Wales, ITV Wales and S4C.

A close proximity to the sea has a moderating influence on temperatures in Cardiff and during winter they can be among the highest in the UK. The minimum average daytime temperature is 2.1 °C. This is for the month of February, when UK minimums are around 0.7 °C. Rainfall is much higher in December and January than February.

Temperatures start to become fairly pleasant from April and in spring the chance of an air frost is much less in Cardiff than other locations in the UK. March sees a few more days of rainfall greater than 1 mm than February but this number falls as we head into April. Spring is the driest season in Cardiff, with rainfall accumulation around 230 mm. There is a notable jump in sunshine hours from March to April; both more than the UK average.

Cardiff's hottest temperatures are usually seen in July, with daytime maxima for this month at 21.7 °C - although August is very close at 21.5 °C. July also has the highest average sunshine hours of any month. Rainfall is around the same as the UK average during summer in Cardiff and august often receives the most. In Cardiff thunder occurs on an average of 11 days a year, compared with 15 to 20 days at many places in England.

September and even October cling on to mild temperatures in Cardiff with the average high in the former approaching 19 °C. Sunshine hours are still quite high in early autumn but in October rainfall does start to significantly increase. Overall autumn is the wettest time in Cardiff, with more 'rain days' than any other season and a higher rainfall accumulation.
