Outlook for the UK over the next 6-30 days

UK Outlook for Friday 6 Mar 2015 to Sunday 15 Mar 2015:

A lot of dry weather during Friday but cloudier conditions and occasional rain in some southern areas may spread north again later, especially across western and northwestern areas. Into the weekend, a northwest/southeast split is expected, with wetter and windier weather in the northwest , especially northwest Scotland, where gales and heavy rain may occur. Drier, brighter conditions more likely in the southeast. Becoming mild across the country and very mild in parts of the south and east. After the weekend, there looks to be a change to more settled weather even across the north at times. Occasional weather systems will bring cloudier interludes with rain, most likely in the north and west. Uncertainty with temperatures, but likely to be slightly above average by day, but with some cold nights.

UK Outlook for Monday 16 Mar 2015 to Monday 30 Mar 2015:

In the second half of March it looks probable that pressure will remain higher than average across the whole of the UK at first, before possibly weakening and becoming more focussed towards the south of the UK by the end of the period. This would bring generally drier conditions, but it is likely that there could be some cloud at times, with some occasional rain or showers particularly across the north. However, the chance of any prolonged wet and windy weather is fairly small. Temperatures will most likely be close to average, perhaps slightly below in the south but some colder nights are possible with the risk of frost, mist and fog in places.
