Headline for The Northwest Highlands
Local areas of heavy showery rain with gusts
How windy? (On the Munros)
Variable 10mph or less early in day, but sudden gusts in rain. Becoming northeasterly 20 to 30mph through afternoon, soonest in north.
Effect of the wind on you?
Negligible for several hours, but ease of walking starting to be affected as speeds rise; prepare for notable wind chill if exposed to increasing wind..
How Wet?
Showery rain, risk lightning
Showery bursts of rain in the morning, mostly in northern and southern areas to start. Showers slow moving, bringing several hours of rain to several areas with lightning risk. With time, showers will tend to push south, turning lighter in the north later in the day.
Cloud on the hills?
Fairly extensive
Shrouding hills fairly widely above 600 to 800m, some breaks at times if drier to 900m or above for periods, most likely central areas. During and after rain, cloud lowering, ragged patches to lower slopes.
Chance of cloud free Munros?
30%
Sunshine and air clarity?
Fairly cloudy; some sun later near coast, and perhaps central areas seeing more glimpses for a time. Visibility often reduced by rain, some periods where very good if dry.
How Cold? (at 900m)
6 or 7C, only slight rise if any, most likely south; cooling a degree or two overnight. Feeling like 0 to -3C if exposed to increasing wind.

High tops often covered
Fairly extensive near coasts in the morning, bases near 500-600m on windward aspects. A lifting trend with time, breaks forming inland, to just varied banks over tops from Easter Ross south. North and western coastal high terrain remains shrouded.
Chance of cloud free Munros?
20%

Mostly cloudy, a few sunny glimpses inland southern areas. Very good visibility out of cloud and rain.

Planning Outlook
As the weekend approaches, wind will shift northerly, moving showers and afternoon thundery downpours further south with time. Generally lighter wind but gusts will be common around showers. Temperature lowering later this week too, dropping close to freezing on high Scottish tops on Friday morning (chance of sleet/snow here) and frost may occur in Highland glens over a couple of nights. More often dry with few lighter showers over the weekend as higher pressure builds into the southwest. Conditions remain on the drier, brighter side early next week, pressure dropping again as the week goes: periods of cloud and rain for most hill groups, and perhaps some stronger wind at times. Detail beyond the weekend is uncertain, and there may well be windows of better weather through the week too.
