Outlook for the UK over the next 6-30 days

UK Outlook for Sunday 8 Mar 2015 to Tuesday 17 Mar 2015:

A northwest/southeast split is likely on Sunday. Wetter weather is expected in the northwest, with outbreaks of rain, perhaps heavy in western Scotland, slowly moving south, possibly reaching northern England by the end of the day before stalling. It will also be windy with gales possible in places. Drier, brighter, less windy conditions are likely in the southeast, with some sunny spells. It will become mild across the country and may be very mild in some eastern parts. From Monday, there looks to be a change to more settled conditions to most parts of the UK, however, occasional weather systems will likely bring cloudier interludes with rain to northern and western parts. There is uncertainty in temperatures, but they are more likely to be average for the time of year.

UK Outlook for Wednesday 18 Mar 2015 to Wednesday 1 Apr 2015:

It looks probable that pressure will remain higher than average across the UK at first. This would bring generally drier than average conditions, but it is likely that there could also be some cloud at times, with some occasional rain or showers particularly across the north. There are signs that a more unsettled regime will be established in late March with wetter than average conditions probably developing in the northwest, but still with drier weather in the southeast.
