Tomorrow | Thursday | Friday

How windy? (On the Munros)

Southeast, switching west to southwesterly into afternoon; speeds may change quickly, risk 30 to 40mph with stronger gusts morning, but also periods of little wind throughout day.

Effect of wind on you?

Risk of arduous walking and significant wind chill for a time morning; becoming small.

How Wet? (Precipitation and its impact)

Rain for several hours

A front moving slowly northeastward brings a risk of rain setting in over several hours, heaviest southern Cairngorms NP. Gradually fading from southwest through afternoon. Becoming sleet or wet snow higher tops.

Cloud on the hills?

Extensive south in rain

Cloud likely to cover areas accessed from Glen Garry and Deeside much of the day, to lower slopes where rain sets in. Toward Strathspey and Monadhliath, often above 800m, with higher breaks away from or prior to rain.

Chance of cloud free Munros?

20% south; 50% north.

Air clarity (below cloud)

Generally overcast, murky southern areas. Possible glimpses of sun around Strathspey. Visibility poor in rain, but very good at times in north.

How Cold? (at 900m)

5C, later falling to 3C. Risk feeling close to -8C in exposure to wind morning.

Freezing Level

Above the summits; may lower close to highest slopes later.

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.
