Next week, the UK is set to experience a significant drop in temperatures due to an incoming cold front. Beginning Saturday, an Arctic air mass will cause widespread frosts and potential snowfall in certain regions. This chilly shift follows the establishment of high pressure over Greenland, which allows cold Arctic air to flow into the UK, resulting in bitter northerly winds. While the late November timing means temperatures will not plummet as drastically as they might in mid-winter, residents should prepare for notably colder conditions.
