Martin,
The RA/RASN started at Guildford about 10Z. I went off to Sainsburys with some 'windscreen sleet' (does this actually count as RASN??) but you could not really see it normally. Then on my way home an hour later it appeared to be just rain. However, in the last 30mins, there has been some visible RASN but the snow element has been very wet. Interesting conditions in the atmosphere above at the moment. Min last night MS0.9c Max today (13Z) 2.7c Phil Guildford |
