UK Braces for Arctic Chill: Frost, Fog, and Then Rain!

Arctic air is set to dominate the UK's weather as the weekend begins, with cold health alerts remaining active for significant parts of England. Saturday is expected to dawn with a sharp, widespread frost, particularly affecting England and Wales, where temperatures could drop to -5C in rural areas. Freezing fog is also a concern in southern and eastern England, posing a risk of slippery surfaces due to ice formation on impact.

While Saturday features bright, dry conditions after morning frost and fog clears, with afternoon temperatures rising, Sunday will usher in unsettled weather. Low pressure arriving from the Atlantic will bring areas of showery rain moving from west to east across much of the UK. The heaviest rainfall is anticipated in Scotland and Northern Ireland, along with southern and western England and Wales. This incoming rain could be beneficial for regions experiencing drought, though parts of eastern England might see less precipitation.
