Planning Outlook

Staying unsettled through the weekend and next week as southwesterly winds prevail and low pressure systems pass to the northwest of Scotland; sustained gales over the mountains, severe or stormy for periods. Rainfall will be frequent and heavy for periods, sometimes showery with hail in the west. Expect very wet ground conditions and further flooding of streams and some rivers. Best chance for dry and bright periods central and south Pennines, though these fleeting. Mild for the time of year, temperatures only just below freezing intermittently on higher Scottish tops, even here will experience spells above freezing with thawing, any lying snow patchy, but beware some icy surfaces on the very highest tops where some refreezing occurs.
