Summary for all mountain areas

A damp atmosphere shrouds most west coastal hills in fog to lower slopes in morning. Some breaks forming for England, Wales & eastern Scotland. Rain heavier in middle of the day in western Scotland, spreading later to NW England and N Wales.

Headline for West Highlands

Blustery. A period of heavier rain; blanket fog western mountains.

How windy? (On the Munros)

West to southwesterly, 15 to 30mph morning into early afternoon, speeds locally varied, suddenly gusty in places. Will tend to drop toward evening, turning northerly up to dusk, but risk increasing again from sunset to 30mph, perhaps 40mph some tops overnight.

Effect of the wind on you?

Periods of buffeting on higher terrain, tending to ease late afternoon. Beware of deteriorating conditions from dusk, with noticeable wind chill in exposure.

How Wet?

Drizzly; steadier rain setting in middle of day.

Rain and drizzle from dawn, although small amounts well inland. By middle of day becoming persistent and heavier, soonest west of Loch Linnhe and on Mull, but fairly widespread rain for a few hours in afternoon. Later tending to break up from northwest, but expect rain or drizzle on and off into the evening.

Cloud on the hills?

Very extensive, particularly near coast

Toward the coast, from lower slopes up, hills may well be persistently foggy. Progressively inland, the cloud base will rise. Toward central highlands, cloud only occasionally below 500m, and breaks to or perhaps above 900m.

Chance of cloud free Munros?

20%

Sunshine and air clarity?

Glimpses of sun, if any, confined to lower slopes well inland. Intermittently very good visibility, but poor in rain - extensively so western areas from lower slopes upwards.

How Cold? (at 900m)

8C, to 10C well inland, but will drop toward 4C into the evening, locally a degree or so lower on higher slopes into the night.

Freezing Level

Above the summits.

Planning Outlook

Low pressure drifts slowly southwards across Britain through Friday into the weekend, followed by improving conditions from the north as pressure builds. Residual areas of rain, drizzle and low cloud may affect Wales, the Pennines and perhaps eastern Scotland through the weekend, whilst west & northwest Scotland become fine and increasingly warm. Most indications favour high pressure influencing Britain into next week, bringing mainly dry and warm weather. Despite some rain this week, most mountain areas will remain very dry underfoot: beware of the risk of fire.
