Most mountains persistently cloud covered; clearing toward central belt

Cloud base will vary, sometimes below 400m mainly near showers within 10 miles of the west coast, where only occasionally reaching 750m. Further east, by midday, most cloud above 650m with breaks to 900m, perhaps 1050m central highlands. On Arran, most cloud above 800m by midday.

Chance of cloud free Munros?

Almost nil most of region; 20% central highlands

Sunshine and air clarity?

Glimpses of sun only, mainly lower slopes well inland from west coast - although the sun in and out near Clyde sea lochs. Hazy western hills. Mostly very good visibility well inland.

Overnight rain, concentrated on more western mountains may well rarely cease all day, particularly Lochaber and Mull. Toward central highlands and south of Oban, the rain progressively less heavy - perhaps only a little drizzle Arran.

Cloud on the hills?

Persistent fog.

High likelihood of persistent fog: near coasts with the sea to the SW, from 200 to 400m upward, whilst elsewhere above typically 600m (800m Ben Wyvis). Chance of a rise in cloud base of a couple of hundred metres extending south.

Chance of cloud free Munros?

10%

Extensively dull and misty. Chance isolated pockets of sun easternmost lower slopes and valleys - but even here hazy.

Planning Outlook

Rain at some stage more or less daily on most mountain areas through the coming week. However, total rainfall small, and frequently dry E & S Wales and S Pennines. Frequently windy Scottish Highlands, whilst progressively southwards, periods of strong winds will less frequent. A brief period of colder weather around the middle of next week will bring snowfall to some northern mountains.
