Latest thoughts from the metoffice. It's interesting to note that they think that there'll be occasional (warmer) fronts moving in from the west at times but these conditions won't last long and the weather will return to cold/settled fairly quickly.
Outlook for Tuesday to Thursday:
Mostly fine in the northwest on Tuesday. Otherwise rather unsettled and cold, with showery outbreaks of rain, especially in the south and east. Some hill snow, and icy patches overnight.
UK Outlook for Thursday 22 Nov 2018 to Saturday 1 Dec 2018:
Throughout this period, the winds look likely to blow in from the east, across continental Europe. This will often bring cloudy skies, with the best of any sunshine in western areas. There is also the likelihood of some showers, these most frequent in eastern parts, but perhaps becoming more widespread and persistent at times. With a chill in the air, there is scope for some sleet or snow, but this will most likely be restricted to the hills. The breeze will make for a marked wind chill at times in the south. With lighter winds further north, and under clear skies at night, overnight frosts are likely to become more common. There is also a small chance of even colder conditions going into early December, in northerly winds.
UK Outlook for Sunday 2 Dec 2018 to Sunday 16 Dec 2018:
Through this period, there may be a continuation of the cold and mainly settled conditions for much of the UK, with some showers coming in from the east. However, there is a chance that during early December the weather pattern may change, with fronts moving in from the west across the Atlantic. This would bring longer spells of rain, interspersed with brighter, showery interludes, and it would also become less cold. However, even if the change does happen, it won't be long before we have more settled conditions again, perhaps by the middle of December. This would mean a return to the colder conditions with overnight frost and fog.
