No idea what happened yesterday there was a big anvil with wispy tops building from the west and was getting closer and closer, to me it seemed a dead cert as it the sky was black, and it was building over a couple of hours, snow started coming on about half 4 here in Paisley then nothing, just fizzled out? There was a dusting when I got back home in Port, although only when I started gaining height. It looked like big flakes had started falling then stopped after about 5 mins. There was a few short showers till about 9 then it stopped and night was sparkling clear and bitter cold.
