.uk... I know I'm getting boring but I'm sure most people are surprised it hasn't settled more! It's a theme that's cropped up on some Web based message boards as well. The only thing I can say for certain is that given heavy enough snow (of the big fluffy flake sort), it *will* settle, even if the roads are soaking wet after rain/melted snow. Until today the last time I saw that in action was the snow event in January 2004, which started with a few minutes of heavy rain which turned to heavy snow and promptly settled. Other than that, there's got to be an obvious reason why the snow's having such trouble settling in this spell. I'd be tempted to say it's the radiation absorbed during the day that's causing it to melt so quickly, but that wouldn't apply to snow falling early in the day. |

Don't know how the snow last night managed to accumulate on the roads at all! Jonathan, or anyone, do you have any information about snowdepths over the East Kent Snowtrap (i.e. the North Downs between Canterbury, Dover, Folkestone and Ashford)? Someone told me that there was "about six inches" this morning. That "about" worries me. If it was the average of several measurements then fine, I'll accept it, but if it was an estimate then I would divide by two or three because people always grossly over- estimate snow-depths.

Philip, Here in Canterbury we got about 5cm generally (8m ASL). There wasn't any more at the University campus (50m ASL). Can't say about the Downs, unfortunately, but six inches seems somewhat of an overestimate. -- Jonathan Stott Canterbury Weather: http://www.canterburyweather.co.uk/ |
