Overview
- Met Office guidance for 1–10 January points to a North Sea low followed by high pressure to the northwest and low pressure to the east, setting up a cold, showery northerly flow.
- Forecasters flag the chance of snow at times, mainly on higher ground and north‑facing coastal areas, with many places otherwise drier than average.
- Temperatures are expected to run below average in the early period before possibly edging nearer to or above average later.
- BBC Weather projects sub‑zero overnight lows in London on some nights around 3–6 January, with days staying cool and largely fine.
- No Met Office severe‑weather warnings are posted for early January, and the 11–25 January outlook carries low confidence with multiple possible scenarios, including milder or more unsettled spells.
