Freezing levels rising above most mountain tops on Sunday as rain moves through, then frequent below freezing on Scottish summits next week. Elsewhere, most precipitation rain with freezing levels often above higher tops (although 600-800m Friday & Saturday). Signs of turning widely colder post-Christmas.
