A cold start this morning, with a few localised mist and fog patches. Then a fine and dry day with patchy cloud and sunny spells. Feeling pleasant in the sunshine with just a light breeze. Maximum Temperature 19C.

Tonight:

Dry with clear spells and light winds overnight, so another chilly one. Once again, a few rural mist and fog patches may develop. Minimum Temperature 3C.

Issued at: 0500 on Mon 22 Sep 2014

UK forecast for the next 5 days

Dry and fine for most, but rain in far northwest.

Today:

A cold start this morning, with a few localised mist and fog patches, then dry and fine for most once again. However rain will edge across northwest Scotland, then into Northern Ireland and the rest of Scotland into the evening.

Tonight:

The cloud and rain will continue to push southeastwards overnight, possibly just about reaching northern parts of northern England by dawn. Elsewhere, dry, clear and cold once again.

Tuesday:

The band of cloud and occasional rain will continue southwards, across the rest of northern England and north Wales by evening. Largely dry and fine either side.

Outlook for Wednesday to Friday:

Cloud and rain clearing southwards on Wednesday with the odd shower following. Largely cloudy on Thursday and Friday with outbreaks of rain or drizzle for many. Breezy throughout, especially Thursday.

Issued at: 0500 on Mon 22 Sep 2014

Outlook for the UK over the next 6-30 days

UK Outlook for Friday 26 Sep 2014 to Sunday 5 Oct 2014:

Fairly cloudy at first, though some sunny intervals developing for central, southern and eastern parts of the UK. Outbreaks of rain are expected for northern and western areas, more persistent for parts of Scotland and Northern Ireland, although clearer, showery weather should follow for a time. It will be quite windy here too. Temperatures generally near or a little above normal. Into the following week, the north and west are likely to remain the windiest and most unsettled parts of the UK, with the best of the weather further south and east. However, a little rain is to be expected here at times. Temperatures should be a little above normal for most. This general northwest-southwest split in the weather is then likely to continue into the start of October.

UK Outlook for Monday 6 Oct 2014 to Monday 20 Oct 2014:

The broadly northwest-southeast split in weather conditions expected to become established for late September and early October is then showing signs of persisting into mid-October. This pattern would leave southern, central and eastern parts tending to see the best of the weather with conditions often fine and dry. Occasional bouts of rain should still be expected, and mist and fog patches may be a problem during morning rush hours but under fine weather it should feel pleasant. Further northwest, conditions are likely to be more unsettled with more frequent outbreaks of rain, perhaps accompanied by strong winds, temperatures here then often closer to average or perhaps even just below at times.

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.
