Will
As an observer I have had to invent a trace of cumulus before now to explain both snow & rain from what looked a perfectly clear sky at night. If I remember correctly on both occasions the winds were strong and from the south or southwest at Kinloss. I have also observed what I reported as diamont dust (probably mistakenly) again falling from clear skies in misty conditions with temperatures well below -5C (if my failing memory serves me well). The only reason I noticed anything at all was ATC were playing there searchlight on me as I was doing the 2100 observation, the ice crystals were barely perceptable on my face, and almost ssem to hang in the air. Hills do have a climate of there own, just one example of this I noticed a few years ago now when we climbed a couple of Munros of the A9, the tops were very icy and the cairns were especially heavily rimed, but the 11Z ascent from Shanwell that day did show the freezing level well above the level we were at.

![]() Thanks Bruce, Last time I saw diamond dust was in 1982 in Bracknell when there was 20 cm snow on the ground and the air temperature was circa -10 deg C. As you say it just sort of hangs in the air, the sky was 8/8 blue and it was glinting in the sunshine, it is not common in the UK. What I saw in last few days were small flakes of snow. PS got my light snow shower this afternoon, from cumulus mediocrus ! ATB, Will. -- News wrote in message ...

That, Will, is exactly what I saw more than once (in essentially clear skies) in the Winter of 1962/3, in Easterlies. I was living in NE Stockport on low ground at the time and it struck me as a little odd to say the least, so I've always remembered it. They were small thin flakes but snowflakes nonetheless, of the kind that might produce fluffy snow on the ground from which you can't easily make snowballs. After some discussions my schoolfriends and I guessed it must have come from somewhere in the Pennines (5 to 10 miles away), either as blown recently fallen snow or from cloud we could not see. It was fascinating to see! Fluffy cheers ![]() -- Dave |
