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 West Highlands

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

How windy? (On the Munros)

Northwest or northerly; some variation in speed through the day, mostly between 20 and 30mph.

Effect of wind on you?

At first may be fairly small, but risk of considerable buffeting and wind chill developing on higher areas.

How Wet?

Areas of persistent snow, easing to showers

Snow and hail showers, locally frequent western mountains, with the precipitation almost constant for a couple of hours resulting in whiteout in some areas. Showers few by afternoon central highlands and Loch Lomond NP. Rain only lowest coastal slopes.

Cloud on the hills?

Extensive, some breaks may develop

Cloud bases will vary markedly. Often extensive above 700-900m, with shafts down to lower slopes near showers, and may shroud many areas to low levels in morning. However, well inland by afternoon, at least fleeting occasions when tops will clear.

Chance of cloud free Munros?

30%

Sunshine and air clarity?

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

How Cold? (at 900m)

-2C dropping through day to -4C. Where exposed, will feel as cold as minus -17C.

Freezing Level

400 or 500m coastal hills and toward the central belt, otherwise 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.
