Few days without gales on the mountains up to Christmas. Precipitation almost daily, particularly western mountains. Freezing levels rising above most mountain tops on Sunday, resulting in a significant thaw. Next week intermittent cycles of freeze and thaw, but frequently below freezing on Scottish summits. Indications favour colder air spreading southwards around or after Christmas Day, with freezing levels dropping significantly, leaving most ground frozen from just above most valleys upwards, and snow falling to lower slopes.
