The UK is preparing for a potential snowstorm as temperatures are expected to drop to -2°C, with an 80% chance of snowfall hitting southern England. Weather maps from WX Charts, which rely on Met Desk data, have turned dark red—indicating a significant likelihood of snowfall, particularly around Greater London.
Snowfall and flurries are forecast to begin around 6 AM, affecting Greater London and the wider southern region. From December 27 to December 30, areas including Gloucestershire and the Cotswolds are also at risk, with predictions highlighting sub-zero temperatures during this period. The advanced GFS modelling system projects temperatures as low as -3°C in Wales, and close to -1°C in Somerset, Hampshire, Suffolk, and Greater London.
Further WX Charts forecasts indicate snow could also fall on New Year’s Day, suggesting that parts of the UK could see flakes on six separate days.
