Patchy rain or drizzle
Rain on and off, or generally drizzly - total amounts small, but may be persistently damp, especially where hills are shrouded in cloud.
Poor visibility
Murky conditions with areas of fog shrouding the hills, making navigation challenging. Map and compass essential.

Headline for The Northwest Highlands
Often damp in west, light rain, low cloud.
How windy? (On the Munros)
Westerly 10-15mph, to 20mph in north for a few hours from dawn, dropping less and becoming variable direction, trending southerly 10-15mph on Skye, often less elsewhere afternoon onward.
Effect of the wind on you?
Mostly small, breezier start in far north.
How Wet?
Patchy rain, drizzle mostly west
A fine drizzle on the high tops and near western coasts and Skye much of the day, some steadier light rain in the morning. Drier windows more often inland and east, but patchy rain and odd heavier moments extend east with time.
Cloud on the hills?
Lowest and most persistent west
Coastal hills shrouded most of the day, from 500m up in the morning, bases rising somewhat but unlikely breaking above 700-800m. Inland, bases to 900m during drier windows, local breaks east, but returning lower in rain.
Chance of cloud free Munros?
10% Skye and west coast; 30% Ben Wyvis area.
Sunshine and air clarity?
Largely cloudy, a few odd glimpses of weak sun mainly east. Visibility largely poor on high terrain and towards west coast, locally better east.

Increasingly extensive and low
Varied cloud banks at first, most persistent around Skye, here likely to shroud hills most or all day, filling in to lower elevations in steady rain. Cloud blanketing hills increasingly widely, bases 300-600m.
Chance of cloud free Munros?
Dropping widely below 10%
Sunshine and air clarity?
High cloud soon thickens to become overcast. Good visibility reducing to poor as rain develops.

Planning Outlook
Low pressure initially to the north of Scotland early in the new week will eventually envelop the whole of Britain next week bringing generally unsettled and cooler conditions increasingly widely. Often blustery widely, west turning northerly winds later in week - becoming notably chilly over higher mountains. Rain extends into Scotland on Monday, turning heavy, then moves south over England and Wales by Monday night into early Tuesday. The rest of the week sees showery rain common for all areas, the rain most persistent in western Scotland, but heavier showery bursts and thundery downpours become widespread mid to late week.
