Summary for all mountain areas
A complex situation: rain in Scotland becoming confined to north-east. Bursts of torrential rain and thunderstorms developing Wales & southern Pennines. Widespread murk and low cloud, unlikely to clear most hills. Strong southerlies in NE Scotland, otherwise winds easing markedly.
Headline for Cairngorms NP and Monadhliath
Strong winds easing; persistent rain many hours, low cloud.
How windy? (On the Munros)
South or southeasterly, 30 to locally 40mph at first, strongest NE Cairngorms NP. Will ease from south to 20mph mid-afternoon, and by evening nearer 10mph.
Effect of wind on you?
Locally difficult walking conditions at first will ease gradually, becoming very small later in day.
Rain for many hours, particularly north-east
Rain persistent across the region during morning, will slowly fragment by afternoon into patchy rain or drizzle from south-west. However, toward NE Cairngorms NP, risk of locally heavy rain lasting most of the day.
Cloud on the hills?
Extensive low cloud, lifting slowly north & west
Very low cloud most areas in morning, but as rain eases, the cloud base lifting to around 700 to 900m or occasionally 1050m, highest north. But risk blanket very low cloud all day Deeside and areas accessed from Glen Garry, lifting only slowly.
Chance of cloud free Munros?
Less than 10% SE Cairngorms NP; 30% by afternoon elsewhere.
Sunshine and air clarity?
Rare glimpses of sun into afternoon; mainly lower areas near Cairngorms. Generally hazy. Fog widely higher areas, but to low levels early on and in east.
How Cold? (at 900m)
Above the summits.
All mountain areas of Britain from Wednesday 7th October 2015
Some uncertainty remains for Wednesday - rain threatens to persist eastern Highlands, perhaps also Borders. Improving from west, but temperatures falling, and freezing levels briefly near higher Scottish summits later and early Thursday. Pressure builds across England and Wales Thursday & Friday, giving fair conditions, although low cloud many western mountains. Toward weekend and beyond, high pressure building toward the east may bring renewed settled weather for several days.
