Planning Outlook
Unsettled weather persists through the late weekend and into next week: a southerly flow is dominant through Monday, lifting freezing levels and brining precipitation to most mountain groups through the early week. The Munros will likely stay below freezing; precipitation will continue to fall as snow on high terrain: snowdrifts from the Cairngorms to central and southern Highlands with a continued risk of flooding here. Gales are likely as well. Southeasterly winds will tend to re-establish later in the week, lowering freezing levels and drawing cloud and precipitation into the Pennines and eastern Scotland, the snow level dropping to middle elevations with time. Cloud and precipitation more patchy in the west with the brightest skies northwest of high summits.
