Summary for all mountain areas

Continuing mild, but gales - or in the north severe gales on many mountains - will make it feel cold due to wind chill. A weakening front will bring a little rain eastwards before a further front brings heavier rain in from the southwest later in the day.

Headline for Cairngorms NP and Monadhliath

Upland gales developing, becoming severe; occasional rain.

How windy? (On the Munros)

Southerly, ranging from 30-45mph morning, strongest higher tops. In afternoon progressively strengthening to 40-55mph.

Effect of the wind on you?

Increasingly difficult conditions. Into afternoon mobility where exposed very strenuous and wind chill becoming severe.

How Wet?

Occasional rain

Rain on and off after dawn will clear later morning. Rain returning from southwest mid to late afternoon; very little all day toward and north of Deeside.

Cloud on the hills?

Extensive generally on higher areas; lowest cloud more southern ranges

Cloud base rising morning, though slowly more southern mountains. Typically in early afternoon around 750-900m from Ben Alder to and east of Drumochter; but will lower again late on in rain. Further north, most cloud above 1050-1200m int the afternoon.

Chance of cloud free Munros?

10% southern mountains to 60% into afternoon more northern areas.

Sunshine and air clarity?

A hint of a brief period of much colder weather around the middle of next week.
