How windy? (On the summits)
Effect of wind on you?
Small chance of an isolated late afternoon shower.
Cloud on the hills?
Mostly confined to east
Blanket cloud shrouding many slopes from valleys or just above valleys upwards, will disperse through middle of day. The cloud is unlikely to reach western hills, and across region, higher slopes will be above the cloud.
Chance of cloud free summits?
Greater than 90%
Sunshine and air clarity?
Sunshine increasingly, in some areas above lower level cloud/fog. Extensive fog morning Borders, mostly or all clearing but leaving very hazy conditions.
How Cold? (at 900m)
All mountain areas of Britain from Friday 19th September 2014
Bursts of rain and a few thunderstorms will extend north as far as southern Scotland on Friday and particularly Saturday. However, colder and much clearer air will spread southwards across Highland Scotland on Saturday and will reach most or all of Wales on Sunday. Next week, starting fine across all mountain areas, but slowly as an area of high pressure sinks southwards, westerly winds, bringing fronts in off the Atlantic will begin to bring deteriorations into northern and western Scotland, and by the end of the week, probably to all mountain areas.
