Summary for all mountain areas

Cold air advances back southwards. A complex area of low pressure NE of Scotland brings areas of frequent or constant snow to the Highlands, although should tend to fade in central areas. Clusters of snow and hail showers for England & Wales, where upland winds up to storm force.

Headline for The Northwest Highlands

Blustery, cold; areas of persistent snow to low levels.

How windy? (On the Munros)

North backing northwesterly; some variation in speed through the day: occasionally 30 or 35mph, but mostly 25mph.

Effect of wind on you?

Expect considerable buffeting and wind chill where exposed most or all day.

How Wet?

Areas of snow, easing to showers

Snow and hail showers, but the precipitation merging to give almost constant snow for a few hours after dawn, giving whiteout conditions. Rain only lowest coastal slopes. Risk isolated thunder.

Cloud on the hills?

Extensive, particularly coastal hills

Cloud bases will vary markedly. Often extensive above 700-900m; with shafts down to lower slopes near showers. Around constant snow, cloud widely covering hills for several hours. However, particularly well inland, at least fleeting occasions when tops will clear.

Chance of cloud free Munros?


Sunshine and air clarity?

Glimpses of weak sunshine developing, mainly inland. Visibility may become excellent some areas, but very poor in cloud and snow.

How Cold? (at 900m)

-4C. Where exposed, will feel as cold as minus -17C.

Freezing Level

400 or 500m coastal hills, but inland near or below freezing from just above glens upward.

Planning Outlook

All mountain areas of Britain from Friday 24th November 2017

Frequently cold due to predominance of northerly winds until the end of the month, and perhaps into December. Snow will accumulate extensively in N and NE Scotland, less so elsewhere in Scotland. Nevertheless, only lowest slopes will see mostly rain, and periods of thaw up to highest summits will be rare. Over England and Wales, intermittent precipitation, often of snow on highest tops.
