Planning Outlook
Becoming colder for all areas during this week, with much mountain terrain frozen again to increasingly lower elevations - soonest toward the north and east of Scotland. East to northeasterly winds in the second half of the week, turning northerly toward the weekend - the distribution of snow showers shifting with time from eastern hills to more north-facing mountains, particularly Scotland. Away from showers later in the week, brighter than recently with sunshine and clearer hills.
