In reply to mark turnbull:
Looks good to me as long as it doesn't get above 3 degrees on the summits the north faces will still be bomber in high pressure. Even if they do rise above this an early start could still provide a good day!

"High pressure will dominate the weather over Britain for a week. Precipitation will be negligible and winds often very
light, especially across Scotland. A persistent cloud layer, shrouding many higher summits, will increasingly break into
next week, again particularly across Scotland. Temperature levels will rise slowly, albeit with frequent night frost, much
terrain will remain frozen.
Toward the end of next week, patches of snow will begin to develop and temperatures may well drop again."
