Planning Outlook

Changeable westerlies prevail onward into early next week, continuing gales over most high terrain. Milder air lifts above freezing to all tops into Tuesday with low cloud, drizzle and rain, most persistent west-northwest Scotland. Likely colder again in Scotland by Wednesday with some further hill snow likely. Some windows of better weather mid-late in the week as higher pressure is nearby - temperatures vary above and just below freezing on Highland tops, more often above freezing England and Wales tops. Some chilly air possible during early April, but drier conditions likely developing with time with more spring sunshine.
