Tomorrow | Tuesday | Wednesday

How windy? (On the Munros)

Variable in direction in morning between 10 and 15mph. Will become northerly in the afternoon and reach 15-20mph; perhaps 25mph higher tops in the west.

Effect of wind on you?

Fairly small; but significant wind chill developing as wind turn northerly in afternoon.

How Wet?

Persistent rain; very wet underfoot in west

A slow-moving front will bring a wet day across the area with persistent rain. Broadly, rain heaviest from Wester Ross down to Skye (very wet underfoot), whilst from Ben Wyvis to near the Great Glen rain will be patchier. Precipitation increasingly falling as snow higher tops during the afternoon; perhaps as low as 800m in the northwest.

Cloud on the hills?

Extensive, particularly western areas

Cloud will shroud the hills throughout the area in fog, often from lower slopes up, for most, if not all, of the day. A few local breaks are possible here and there; but these won't last long. Bases may break and lift across western coastal hills into the evening.

Chance of cloud free Munros?

10%

Sunshine and air clarity?

Generally overcast. Hazy.

How Cold? (at 900m)

Morning; 4 to 7C, coldest west coast. Afternoon: Temperatures lowering from northwest to 0 to 2C by late afternoon.

Freezing Level

Above the summits; lowering to 900-1100m from the northwest through the afternoon.

Planning Outlook

All mountain areas of Britain from Tuesday 22nd May 2018

Extensively fine, often sunny with cloud rarely covering the hills over the next 7 to 10 days. However, in the afternoons, isolated thunderstorms are likely on some days, mainly England and Wales and later in the week as eastern winds set in, fog will intermittently envelop eastern hills. In Scotland, despite sustained snow melt some higher routes will remain blocked by snow for some days yet.
