How windy? (On the summits)
Very low confidence near centres of low pressure: Varied direction, possible marked lull but anticipate up to 45mph.
Effect of the wind on you?
Sometimes small, but zones where wind chill significant and walking difficult - these challenging conditions could set in abruptly.
How Wet?
Periods of rain
Areas of rain will circulate within general low pressure, perhaps falling as snow on higher tops late in day - when it will often be dry, although still risk of showers.
Cloud on the hills?
Fog extensive, although cloud base likely to rise
Fog in some areas from lower slopes up, and few breaks above 600m. Probably an improvement as most cloud rises to above 750m - timing uncertain.
Chance of cloud free summits?
40%
Sunshine and air clarity?
Sunshine occasionally, most likely afternoon. Regions of very poor visibility - but often very good later in day.
How Cold? (at 750m)
3C
Freezing Level
Above the summits.
Planning Outlook
Pressure will fall over the weekend: a little rain for some western mountains on Saturday, but more widespread rain (snow higher areas Scottish Highlands) on Sunday - albeit the detail for Sunday is unusually uncertain (for a 3 day forecast). Cold often dry conditions will return on Monday, but beyond extensive rain (sometimes snow higher areas) and strong winds probable, although presently Scotland, particularly the Highlands may have only snow showers in the cold air.
