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 Brecon Beacons

Upland gales. A few showers, hail or snow high tops.

How windy? (On the summits)

Southwest later westerly; 40 to often 50mph.

Effect of wind on you?

Arduous conditions across the hills all day. Significant wind chill where exposed.

How Wet?

A few showers, mainly west

Areas of showers may spread from the west, these possibly well scattered, but risk locally frequent bursts of rain or hail for a few hours, mainly on western hills. Very wet underfoot; many rivers in spate, particularly Brecon Beacons/W Wales.

Cloud on the hills?

Mostly confined to higher tops

Most likely cloud only occasionally below 700m, perhaps persistent for a few hours on western hills, but frequently many summits cloud free, especially toward east.

Chance of cloud free summits?

40% west; 60% east.

Sunshine and air clarity?

Occasional sunshine, but sheet of high level cloud will progressively weaken the sun. Visibility often very good.

How Cold? (at 750m)

1 to -1C; generally falling through day. Where exposed will feel as cold as -12C..

Freezing Level

750 to 850m, but by late afternoon, may be nearer 650m.

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.
