Met office update
UK Outlook for Sunday 19 Nov 2017 to Tuesday 28 Nov 2017:
After a cold start for some, it will turn milder on Sunday with outbreaks of rain spreading across most areas, this perhaps turning to snow across parts of Scotland, where it probably stays colder. This will clear, allowing colder air to spread to all areas again on Monday, with a mixture of sunshine and showers. These could turn wintry in the northeast and it will become windy with gales developing in the north. The rest of this week will remain changeable with further spells of wet, windy and generally milder weather, although there remains the risk of snow in the north. This will be interspersed with drier, brighter and colder spells, although there could be frost and fog overnight and in the mornings. Overall, temperatures will be colder than normal.
UK Outlook for Wednesday 29 Nov 2017 to Wednesday 13 Dec 2017:
Towards the end of November and into early December, weather patterns may be rather slow to evolve, with a greater chance of drier, brighter and colder weather becoming established, particularly at first. This would lead to temperatures being below normal with more widespread frost and fog. However, there remains the chance that there will be some milder interludes, especially later on, bringing some wet and windy weather, with the risk of some snow across northern parts.
