Viewing Weather Forecast for Friday 28th August 2015
Forecast last updated on Thursday 27th August 2015 at 3:54pm
Summary for all mountain areas
Broadly showery, with the showers tending to transfer inland (from western hills) during the day. However, as a front approaches western Scotland, showery rain will become frequent here later in the day, and across the Highlands, upland winds will later approach gale force.
Headline for The Northwest Highlands
Increasingly windy, and later wet.
How windy? (On the Munros)
South to southwesterly, 30mph, but into afternoon, from west strengthening 35 to mostly 40mph.
Effect of wind on you?
Likely to impede walking across the hills before later making walking increasingly difficult.
Increasingly showery; small risk lightning
Areas of showers, most frequent west coastal mountains on/near Skye north to Ullapool in morning. Into the afternoon, the rain will become increasingly frequent and later afternoon spread well inland and into Sutherland. Small risk thunder.
Cloud on the hills?
Extensive west; particularly southwestern areas
Rarely if at all clearing higher western areas from Torridon south, and dropping below 500-600m in rain, particularly afternoon. East of Loch Cluanie to Achnasheen and across Sutherland, intermittent breaks above 1000m, though here too may deteriorate later in rain.
Chance of cloud free Munros?
10% western hills south of Ullapool to 30% elsewhere
Sunshine and air clarity?
Glimpses of sunshine, mostly toward east and in Sutherland. Often foggy, particularly western tops, but below cloud and away from rain, visibility excellent.
How Cold? (at 900m)
6 rising to 8C
Above the summits
All mountain areas of Britain from Saturday 29th August 2015
A lengthy showery period of weather over the coming week. However, particularly next week, as the wind turns northerly, cloud base will often lift above the summits and the air will be very clear indeed, giving superb views. Winds will also be fairly light. Not warm: some valleys will have overnight slight frost. Later next week, rain, if any, will become rare, but particularly valley temperatures will remain low at night.
