How windy? (On the Munros)
South-southwesterly 40 to 60mph, some uncertainty of peak speed, risk 70mph+ high tops and coastal mountains.
Effect of the wind on you?
Widely arduous, but risk of more difficult or severe conditions ongoing, particularly toward coasts.

A little rain in the wind
Occasional pulses of rain may run onto coastal areas in the west. Spots of rain in the wind elsewhere, some slopes often damp, but small amounts of rain in total.
Cloud on the hills?
Most persistent south/western areas
Covering many hills all day, to some mid-slopes near coasts, but mostly above 900m inland, breaks higher up north and east of Rannoch Moor and Ben Nevis.
Chance of cloud free Munros?
30%
Sunshine and air clarity?
Glimpses of sun mostly near Glen Spean. Hazy, visibility reduced if rain occurs.
How Cold? (at 900m)
4C, may start to drop into evening. Feeling near -10C in the wind.
Freezing Level

Planning Outlook
A very unsettled pattern as southwesterly winds prevail and low pressure systems move in from the Atlantic, sustained gales over the mountains, severe or stormy for periods. Temperatures only close to freezing on higher Scottish tops this week, even here will experience spells above freezing with thawing, leaving snow increasingly patchy, but beware some icy surfaces on the very highest tops where some refreezing occurs. Drier for most places on Thursday this week, otherwise rainfall will be frequent and heavy, sometimes showery with hail. Expect wet ground conditions and further flooding of streams and some rivers.
