UK Outlook for Tuesday 3 Jan 2017 to Thursday 12 Jan 2017:
It'll be cold and bright across England and Wales on Tuesday, although cloudier and milder conditions across Scotland will gradually move southwards across the whole of the UK, with some rain, mainly over the hills. Largely cloudy, milder and windier for most on Wednesday, with some brighter spells in the east. Thursday and Friday will be dominated by a west to north-westerly flow, with wet and windy conditions moving from west to east, with gales in places. Into the weekend and next week we'll gradually see high pressure building to the west, which will allow colder conditions to develop for many, with some wintry showers in places, particularly around coastal areas. Chilly by night, with widespread frost and fog, which may persist during the day.

UK Outlook for Friday 13 Jan 2017 to Friday 27 Jan 2017:
Signals suggest that the most likely scenario for this period is high pressure being dominant across most of the UK. Leading to increasing dry and quiet spells, and a greater likelihood of cold weather with frost and fog by night. However, there may be a few spells of unsettled weather, most likely in north-western parts. In general, temperatures are likely to be cold for the time of year in those settled periods. However, it may turn milder at times in association with any periods of more unsettled weather in the northwest.
