Showery, snow on hills; frosty mornings

It will be turning much colder during the week ahead. The first push of chilly air affects northern Britain on Sunday when showers will give snow on the Scottish mountains. A widespread frost is expected on Monday morning. Things may become briefly milder, but a more direct northerly wind develops by midweek. Air coming straight from the Arctic brings a risk of snow showers to low levels in northern Britain. Currently, the Bonfire Night weekend is looking chilly and wet.

Chance of fog patches in the morning in the far south-west, and a rural frost is possible in Wales. Highs 11 to 16C.

Sunday 29/10/17
