Outlook for the UK over the next 6-30 days

UK Outlook for Saturday 27 Dec 2014 to Monday 5 Jan 2015:

Most places will be wet and windy on Saturday, with gales or sever gales developing in places. Southeastern areas of England may stay dry at first, however. Cloud and rain are expected to clear erratically eastwards during Sunday leaving sunny spells and scattered blustery showers. These will be most frequent across northern and western Britain, becoming wintry with snow in the north. Temperatures will initially be above average but fall below as the rain clears. It will become colder into the following week with snow showers developing across the north. These may spread southwards at times and it will be frosty with freezing fog patches possible. It may turn more unsettled with time, with wetter and windier conditions returning from the west, and temperatures becoming nearer normal.

UK Outlook for Tuesday 6 Jan 2015 to Tuesday 20 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.
