Overview
- The Met Office long-range outlook to December 23 mentions no UK snow and indicates temperatures will probably be above average.
- Short-range model runs from GFS, WXCHARTS and Netweather point to a December 1–4 Arctic intrusion with localized accumulations, including up to about 17cm in the Cairngorms on some charts.
- BBC Weather projects high pressure bringing a drier, relatively mild first week of December for many areas.
- Official guidance keeps any early wintry precipitation largely confined to northern high ground, with unsettled, wetter conditions elsewhere at times.
- Bookmakers shortened White Christmas odds after last week’s cold snap, but forecasters emphasize confidence on Christmas Day snow only improves within about five days.
