..... a sprinkling of what an observer I used to work with at Finningley
called 'sago'; snow grains scattered about - not sure exactly what time they fell, but before 06Z and after 23Z last night - I suspect that after the main frontal stuff cleared (by 21Z yesterday/Tuesday) we had some stratus formation, and they fell from that - nothing showing on the radar from the trough line this far west, so unlikely to be from something deeper. [ Can someone remind me - because I've forgotten ;-( .... if this is the *only* 'wintry' precipitation in this 24hr, as they seem likely to be for us, does this count as a 'day of snow'? ] -- Martin Rowley: data via - http://homepage.ntlworld.com/booty.weather/metindex.htm Bracknell (Wooden Hill/Tawfield), Berkshire NGR: SU 854 667 Lat: 51DEG23MIN30SEC(N): Long: 00DEG46MIN28SEC(W) |

To show how fine the stuff was, quite a few grains fell right through the rain-gauge funnel into the collector. Thanks again, Martin. |
