Planning Outlook
A changeable southwesterly regime continues through the weekend into early next week. Colder for a time with lowering freezing levels on Saturday allowing some refreezing of higher mountain terrain mainly in Scotland, the snowpack on high mountains consolidating following recent thawing. Early low frosts possible into north England as well. Milder air and thawing returns into Sunday, accompanied by rain and upland gales. During next week, higher pressure is expected to develop around the British Isles, bringing quieter weather, drier for most with lighter winds. Some fronts may continue to graze northwest Scotland with rain and stronger winds. Temperatures tending to be on the milder side during early March, occasional cooler winds lowering freezing levels, but winter conditions only on high Munros.
