How windy? (On the Munros)

Southwest may turn westerly, risk 60-70mph around dawn, likely easing, soon typically between 25 and 40mph.

Effect of the wind on you?

Stormy conditions at first are likely to lessen, but expect arduous walking conditions and marked wind chill most of the day.

How Wet?

Early rain, then showery

A belt of heavy rain is likely to soon clear southwards in the morning, but followed by showery rain, becoming increasingly frequent on western hills. Drier toward the central Highlands.

Cloud on the hills?

Fairly extensive on higher terrain

Extensive cloud at various levels across the hills at first, tending to lift and break toward higher slopes, but is likely to cover most summits frequently through the day, bases varied in and out of rain. Best breaks developing well inland.

Chance of cloud free Munros?

30%

Sunshine and air clarity?

Glimpses of sun, mainly inland areas. Visibility fairly good away from rain, but a general slight haze.

How Cold? (at 900m)

Starting at 8C, but lowering through day to around 5C.

Freezing Level

Above the summits, but by dusk will have dropped close to highest tops (around 1400m).

Planning Outlook

High pressure will drift southwards and southwesterly winds will strengthen across Britain in the first half of the week, soonest across Scotland. Staying windy through into next weekend, gales or sometimes severe gales on higher mountains, particularly Scotland. Rain will become frequent in western Scotland as fronts come in from the Atlantic. Spells of rain elsewhere - less wet for Wales and southern Pennines, although a risk of heavier rain moving further south by the weekend. Temperatures will vary through the next 10 days, sometimes fairly warm and humid, but chiller air spreading from the northwest at times - Scottish high tops occasionally near freezing point.
