“Elsewhere, though we’ll see the mist and fog slowly clear, it could remain quite murky for a lot of the morning across central and eastern areas.
“The best sunshine will be across northern areas of Scotland, but further south and west, you can see things starting to change a little bit [by Saturday afternoon] with a greater risk of some showers.”
