Forecast last updated on Tuesday 25th November 2014 at 1:04pm
Summary for all mountain areas
Light winds on the mountains. As warmer air (over colder very humid air near the ground), & over England, a front, extends north, fog will shroud most hills, in some areas from valleys up. However, these conditions will be patchy in W & N Scotland where some summits cloud free.
Headline for The Northwest Highlands
Light wind; many summits cloud free.
How windy? (On the Munros)
Southerly, 15 to 20mph.
Effect of wind on you?
No rain daylight
Here and there, a little rain, or a dusting of snow some higher summits overnight - fine daylight.
Cloud on the hills?
Fragments of fog/cloud from glens upward after dawn. Slowly the cloud will break to clear many higher summits, whilst others, and in places lower slopes, remain in fog all day.
Chance of cloud free Munros?
30% rising to 60%
Sunshine and air clarity?
Sunshine increasingly coming through. The air very clear, but fog, most widespread in morning, present from glens upward.
How Cold? (at 900m)
0 to 2C
Very gradual drop of temperature with height, falling below zero above 900-1200m. Slight frost some glens, mainly morning.
All mountain areas of Britain from Thursday 27th November 2014
Low cloud & occasional rain into the weekend, particularly eastern hills. On higher Scottish tops, a little snow. A front is then likely to bring 'cleaner' (less murk & low cloud) air to Britain, together with rain, & then showers (mainly W Scotland). Looking well into December, inspection of charts from the main forecast centres, suggests lower summit temperatures, freezing level typically 1000m, but relatively low precipitation next week (eastern mountains most at threat). Beyond, a few forecasts indicate frequent gales and precipitation in southwesterlies, but most suggest little change in freezing level, gradual accumulation of precipitation (most eastern Scotland).
