Forecast last updated on Tuesday 19th November 2019 at 3:14pm

How windy? (On the Munros)

Southeasterly on many exposed areas 35-40mph with stronger gusts in places, particularly coastal mountains, but lower speeds in some areas, perhaps only 20-25mph locally inland.

Effect of wind on you?

Blustery, strongest winds not necessarily on highest tops. Significant wind chill. Sudden gusts running downslope.

How Wet? (Precipitation and its impact)

Occasional light precipitation, mostly near coasts

Risk of a little rain from dawn around west coast, sleet or snow flurries higher slopes. This mostly moving away westward, or giving occasional precipitation through day on coastal hills. Inland substantially dry, isolated snow flurries.

Cloud on the hills?

Areas of low cloud, very little Lochaber

Banks of low cloud at 600m or locally lower Loch Lomond NP, or 700m central highlands. Patches around 800m western summits, mostly around early precipitation, otherwise Lochaber often clear or clearing. Some higher tops extensively cloud free (perhaps above lower cloud).

Chance of cloud free Munros?

40% south, to 70% near/west of Loch Linnhe.

Sunshine?
Air clarity (below cloud)

Patches of weak sunshine - often through thin high level cloud. Visibility varied, hazy some lower slopes, but superb higher areas Lochaber.

How Cold? (at 900m)

-1C, but perhaps 3C western areas, and on higher tops just above freezing point. In exposure to strongest wind, feeling close to -15C.

Freezing Level

800m, but above summits toward west coast, particularly west of Loch Linnhe. However, nearly all terrain frozen.

Planning Outlook

All mountain areas of Britain from Thursday 21st November 2019

Areas of low pressure lying to the west & southwest of Britain will make gradual progress across the country later this week. A slow lift of temperature, although winter conditions will prevail across higher Scottish mountains through the weekend. Even next week in the Highlands, periods of thaw are expected to be short-lived. Occasional snowfalls. Least precipitation again in the far north/northwest. Tops in England & Wales more commonly above freezing point. Periods of rain or showers coming in from the south/southwest. Winds varied through weekend, but risk bouts of gales next week.
