Southerly 20 to 30mph; marked increase later in the afternoon and into the evening to 35 to 50mph; strongest west coast. Reaching 70-80mph from dusk into night.

Effect of the wind on you?

Scattered showers, although for a time in the morning frequent, and falling as snow above 900-1000m. Then largely dry for a few hours middle of day. Toward dusk, heavy rain (briefly summit snow) setting in onward into night, arriving soonest near west coast by late afternoon.

Cloud on the hills?

Extensive higher slopes.

Cloud will cover higher slopes above 800-1000m fairly extensively through the day, in showers shafts down to 600m. Occasional breaks, mostly into afternoon, generally best in northern Lochaber. Will lower later in day near west coast as rain arrives.

How windy? (On the Munros)

Westerly 45 to 60mph, may reach 70mph for periods.

Effect of the wind on you?

Difficult conditions across the mountains through the day, sudden powerful squalls around showers. Severe wind chill.

Clusters of showers coming in from the west, may merge to constant precipitation for periods, particularly early in the day. Hail, and snow at times below 500m. Chance isolated thunder.

Cloud on the hills?

Varied, but often covering tops

Cloud bases changing quickly between showers: often extensive above 800m, but shafts of cloud sometimes below 500m, particularly in west. Fleeting breaks to higher summits mostly well inland.

Chance of cloud free Munros?

20%

Sunshine and air clarity?

Brief bursts of sun away from showers. General slight haze, sometimes very good visibility, but suddenly reduced by showers.

How Cold? (at 900m)

-3C

Freezing Level

600 to 800m, varied in and out of precipitation; lowering up to dusk.

Planning Outlook

Very unsettled through the middle of this week as a series of low pressure systems move to the north of Britain. Persistent gale force winds across the mountains, stormy at times. Heavy rain will make western areas very wet underfoot. Temperatures falling below freezing on higher mountains, particularly by Thursday, resulting in some fresh snow accumulations on tops. Heavy showers will also contain hail and a risk of thunder. Scottish mountains likely to stay sub-zero into the weekend, with some freeze and thaw cycles elsewhere. Into next week, indications favour an improvement from the south as high pressure rebuilds.
