http://www.metoffice.gov.uk/public/weather/forecast UK Outlook for Sunday 17 Jan 2016 to Tuesday 26 Jan 2016:
The weekend will continue cold and bright for most with widespread overnight frosts. There will be a few sleet or snow showers, mainly in the north and east. The start of next week should continue much the same, although more unsettled conditions are likely to spread slowly in from the west early to mid week onwards, with temperatures returning to near normal. There is the potential for a period of snow before the onset of the milder conditions. The rest of the period should be changeable with showers or longer spells of rain, interspersed with some drier and brighter conditions. The wettest conditions occurring in the north and west, where it could turn windy at times.
UK Outlook for Wednesday 27 Jan 2016 to Wednesday 10 Feb 2016:
The weather looks set to be rather changeable throughout the outlook period with rain and hill snow at times, interspersed with some dry and brighter interludes. The rain and showers are likely to be heaviest and most frequent in the northwest. Further south higher than normal pressure is likely therefore drier than normal conditions are expected overall. Overall, temperatures are expected to be around normal for the time of year although day to day variations are likely depending on the weather systems passing through.
So cold "will" last up to middle of next week with unsettled conditions "likely" from midweek on. The GFS had us in the mild air by Sunday evening earlier this week, but is slowly changing its tune. Locally, not globally, it has been an abysmal performance from this model, on this occasion.
