Re: The Mother of all Snow Ramping Threads 2...
Was 9.3c at 8pm aonach mor summit...
That's either very wrong or a record, surely?
Not a record and probably not wrong (though this AWS has had some issues recently). It's a consequence of both a humidity inversion and Foehn effect off the higher peaks in the Nevis Range which are upwind of Aonach Mor. It is currently +7°c at 2800ft at Glencoe and +13°c was recorded this evening at the summit of CairnGorm.
Any idea what the record is, Alan? The figures from the AWS feed showed a brief peak in Cairngorm Summit temperatures above 15 C! There was also an error message though, so I don’t know how reliable they were.
Given the set-up, these temperatures are not meteorologically impossible mind...but surely it’s never been that warm up there in mid-February before?!
