.... (0730Z): first gentle flakes of snow falling now ... no impact as
yet surface/visibility, but with ground surface solidly below freezing, anything coming down will lie immediately. Overnight minimum -6.6°C//current OAT = -1.5°C. Little wind. Traffic (light/no schools) passing OK currently. Martin. -- Martin Rowley West Moors, East Dorset (UK): 17m (56ft) amsl Lat: 50.82N Long: 01.88W NGR: SU 082 023 |

Traffic (light/no schools) passing OK currently. .... (0800Z): now steady, but still light, snow: OAT = -1.4°C, light wind - visibility now affected but still reasonable ~ 4km (probably some BR element making up the majority of visibility reduction); surfaces beginning to pick up a snow cover. Traffic still OK ... local bus passed ... only 5 minutes late. Martin. -- Martin Rowley West Moors, East Dorset (UK): 17m (56ft) amsl Lat: 50.82N Long: 01.88W NGR: SU 082 023 |

It's the first time for a long time that I've almost felt like turning the lights on after 8am. Nick |

wind - visibility now affected but still reasonable ~ 4km (probably some BR element making up the majority of visibility reduction); surfaces beginning to pick up a snow cover. Traffic still OK ... local bus passed ... only 5 minutes late. .... (0900Z): continuous PPN .. mainly slight past hour but short period moderate snow; visibility now down to ~1500M (combination snow/general reduction due mist/haze); new cover snow ~1 cm, total of all snow mean= 2cm, but odd pockets max 3 cm. OAT = -0.8°C//DP = -2.6°C. Traffic still OK .. steady but light .. many decided not to bother I think.

OAT = -0.8°C//DP = -2.6°C. Traffic still OK .. steady but light .. many decided not to bother I think. .... (1000Z): moderate snow began a few minutes ago, otherwise slight (occasionally 'noisy' as if there was a warmer layer intercepting the PPN aloft). OAT = -0.5°C. Visibility ~800M. New snow depth now up to 2 cm over undisturbed surfaces [total representative snow ~ 4cm] - and even trafficked areas have a shallow cover. Traffic slow/careful but moving, but I think the buses have given up and re-cycling hasn't turned up .. probably H&S initially as the roads are passable with care but it's probably a realistic decision given the state of the pavements.

Lows coming in from the southwest are almost guaranteed not to produce snow round here, even if the mild air doesn't get in - just about all our falls are from winds with a northerly component.
