Forecast last updated on Tuesday 15th October 2019 at 4:34pm

How windy? (On the Munros)

Southeast soon switching west to southwesterly; speeds may change quickly, gusty around 40mph from dawn, then typically nearer 20-25mph or at times less; strongest in south.

Effect of wind on you?

Blustery on higher terrain at first, although becoming fairly small. Chilly in exposure.

How Wet? (Precipitation and its impact)

Heavy rain, then a few showers

A front passing slowly northeastward brings heavy rain for several hours in morning, slowest to clear across central highlands, lasting into afternoon here. After a drier window, scattered heavy showers follow from the west, with hail, and snow higher tops.

Cloud on the hills?

Extensive, widely low in rain; bases lifting PM.

Cloud likely to cover higher terrain much of the day, or widely to lower slopes in rain. Bases tending to lift as rain moves through. Fleeting breaks to higher tops possible later away from showers.

Chance of cloud free Munros?

20% rising to 40%.

Sunshine?
Air clarity (below cloud)

Brief bursts of sun developing from west; otherwise overcast, murky in rain morning. Visibility very poor in rain or showers, but intermittently very good afternoon.

How Cold? (at 900m)

5C around dawn, but may soon drop to 2 or 3C. Feeling close to -5C in exposure to wind.

Freezing Level

Starting above the summits, but dropping below freezing above 1200-1300m as the day progresses.

Planning Outlook

All mountain areas of Britain from Thursday 17th October 2019

Through the weekend, areas of rain or showers will rotate around a slow-moving centre of low pressure, some heavy bursts with hail and thunder, but also areas which escape dry most or all of a day. Wind speeds varied, local gales at times, but also marked lulls. Temperatures on the cool side, persistently near or below freezing point on higher Scottish Munros with snow likely to fall and lie above about 1100m. Fairly benign autumn conditions are expected early next week as pressure builds. Milder southwesterlies may then return with some wind and rain possible by midweek.
