Outlook for the UK over the next 6-30 days

UK Outlook for Friday 26 Dec 2014 to Sunday 4 Jan 2015:

A cold and largely fine start to Boxing Day with a widespread frost likely. Remaining dry for most of the day, but unsettled conditions pushing eastwards later, with rain, perhaps transient hill snow, and strong winds developing, with a risk of gales, most likely in north and west. During the weekend, unsettled, slightly milder and windy conditions are most likely across the UK, with periods of rain or showers. Into the following week, more settled conditions may push into western parts, and outbreaks of rain and showers will then primarily affect northern and eastern areas, with snow possible to lower levels in the north. Thereafter, the most likely solution is for periods of frontal rain and milder temperatures, but also some good spells of dry weather, especially in the south.

UK Outlook for Monday 5 Jan 2015 to Monday 19 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 southern 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 possible, particularly over the high ground.
