In reply to Ron Walker:
Complicated frontal system wandering around and straddling the Highlands at the moment with cold/warm temps either side. Doesn't surprise me at all that there's a temperature disparity Slochd to Loch Ness/Glen Affric even though they're not too far apart. Aonach Mor (1130m) summit temp at 20.00hrs today -0.5 degrees but Bealach na Ba (773m) -1.6 degrees at same time - both Met Office readings. (It was +3.4 at the same time down at Glen Ogle.)
Same picture for snowfall/rain today in the Highlands. Next to no new snow at summit level (1050m-1100m) at Creag Meagaidh up 'til about 1pm today, but snowfall above 900m at Aonach Mor and on the Ben.
I know....a weather geek (sorry, it's part of my job!) but I'll be put back in my box soon and will shut up....
