Headline for The Northwest Highlands

Blustery; west coast gales and snow showers

How windy? (On the Munros)

Southerly 30-35mph inland, 40-50mph near the coast, strongest over Skye. Trending southwesterly and easing, largely 25-30mph inland, remaining up to 40mph over Skye and nearby high tops.

Effect of the wind on you?

Blustery in exposure; balance and stability affected all day along the west coast, particularly Skye where bracing may be required for stability. Significant wind chill.

How Wet?

West coastal rain/snow showers, few inland

Frequent showery rain most of the day onto Skye. Patches increasingly drift northward along the coast; snow above 800m, 700m inland. Some patches inland as well, mostly south, a few drift north.

Cloud on the hills?

Mostly shrouded south, then high terrain north

Fairly extensive over high terrain of the Skye and inland southern areas with lower banks in rain, locally down to 600m or lower. Well-broken in the north at first though banks increasingly drifting above 1000m afternoon, most frequent near the west coast.

Chance of cloud free Munros?

30%; 60% early in the north

Sunshine and air clarity?

Sunny bursts in the north and east in the morning, cloud gradually builds for only glimpses afternoon. Visibility excellent away from showers but very poor where in snow.

Effect of the wind on you?

Comfortable walking affected from dawn, deteriorating to difficult conditions into and overnight. Significant wind chill.

How Wet?

Early patchy snow, late rain; most south

Patchy morning sleet/snow on Skye and nearby, some patches drifting north but trending dry for several hours. Rain (snow on high terrain) then arrives from the south late afternoon with patches more widely overnight.

Cloud on the hills?

Mostly south and eastern hills, variable

Fairly extensive on south and eastern hills from 700m up, lower in the south early in patchy snow. A brief lifting and breaking trend, notably near the west coast where breaks may reach some summits, but lowering again afternoon into night.

Chance of cloud free Munros?

30%, 50% west coast for a few hours

Sunshine and air clarity?

Some morning sun in the north, becoming widely overcast. Very good visibility.

How Cold? (at 900m)

Around 0C, little change with height. Will rise in the late overnight hours. Feeling like -15C in strong wind.

Freezing Level

Poorly defined, 600-800m though frosts at lower elevations, including in glens. Rising overnight.

Planning Outlook

Low pressure circulating to the west and north will dominate the weather for the next 7 to 10 days, bringing generally unsettled weather. A brief period of slack pressure on Thursday into Friday will ease winds for a time though patchy rain will linger in several areas. Strong southwesterly winds return over the weekend bringing cloud and rain to many mountains, most persistent on southwestern slopes. Temperatures and freezing level will vary, but staying chilly with highest terrain likely near or below 0C. Several low pressure systems with then pass through next week, brining frequent periods of cloud, rain, and strong wind, likely gale force on high terrain at times. Occasional windows of dry, brighter weather will occur, best chance east.
