Summary for all mountain areas

Early rain, improving to sun and clear hills, chilly breeze.

Occasional cloud banks on high southern slopes, rolling over tops, but more often clear well into the day. Cloud will begin to more extensively shroud tops through afternoon, progressively lowering on southern slopes; north Cairngorms stay clear well into the day.

Chance of cloud free Munros?

70%, lowering to 30% later

Sunshine and air clarity?

Patchy sun through high cloud, tending to cloud over as afternoon goes. Very good visibility.

Planning Outlook

Southwesterly winds increase again on Thursday and rain later moves into western Scotland, but elsewhere is likely dry, bright in Wales and much of England. A variable outlook continues into the weekend and beyond with high pressure building from the south at times with fairly warm and dry conditions, but Atlantic systems still pass to the north bringing occasional rain and showers toward western Scotland at least, strong wind here with sustained gales in the north. Next week remains on the unsettled side: west-southwesterly wind with bands of rain passing over most mountains, but a trend towards higher pressure brings longer settled windows into October.
