Sat 3 Jan Wales

Northerly winds will bring a spell of very cold, wintry conditions to much of if not all of the UK through at least the early part of this period. These will bring snow showers to areas that are exposed to onshore winds. Subtle day-to-day changes in wind direction will change the places most exposed to the showers, but where they occur some significant accumulations of snow are likely. There are likely to be some more coherent bands of sleet and snow working south, and these may bring a risk of more prolonged and widespread wintry precipitation affecting some inland areas. Things become less certain by the second week of January, however it's possible the cold conditions may persist with an ongoing risk of winter hazards across much of the UK.
