Outlook for the UK over the next 6-30 days

UK Outlook for Thursday 30 Oct 2014 to Saturday 8 Nov 2014:

Becoming generally cloudy across the UK, but staying dry with bright spells across southern and eastern parts on Thursday. Northern and western parts will become wetter with outbreaks of rain. The rain will likely become heavier and more persistent later that day. Winds also increase, becoming strong in the west, and gales may develop across the far northwest. A north-south split then looks most likely to dominate. The most wetter, windier conditions likely in the north and northwest; with gales, perhaps even severe gales in the far northwest, next weekend. The best of the drier weather likely in the south and southeast; although there is likely to be some rain here at times. Temperatures generally near normal, but perhaps falling slightly below average later with snow on Scottish mountains possible.

UK Outlook for Sunday 9 Nov 2014 to Sunday 23 Nov 2014:

The main signal is for a continuation of a north-south split during the second week of November. During this period, the generally westerly flow is likely to bring spells of wet and windy weather, mostly affecting northern and some western areas. However, southern and some eastern areas will probably see more in the way of drier and settled conditions increasing the likelihood of some sunshine, but also the risk of frost, mist and fog overnight, the latter of which could be slow to clear. After this it looks set to turn more changeable across the south and east. Daytime temperatures will probably be near or a little above normal, although feeling cooler during any wet and windy spells.

Cardiff weather

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 230mm. 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.
