Planning Outlook

A fine start to the week for many places, but strengthening winds and a spell of heavy rain arriving from the northwest during Monday advances southwards into Tuesday. Cold, wintry conditions follow across the mountains into midweek, falling sub-zero across all hills of Britain above 600-700m later Tuesday into Wednesday. Significant chill factor from gale force west then northwesterly winds. Showery hail and snow falling toward lower elevations. High pressure to the southwest then likely rebuilds to settle things again toward next weekend and temperatures will tend to recover. A mixed west to southwesterly flow likely continues to bring more changeable conditions to west and northwest Scotland.
