Darren - if Tunbridge Wells gets anywhere near that, I would be delighted. Its had an absolute shocker this year with a grand total of around 5 minutes snow cover.
This despite elevation of around 140m asl.
I think the problem is that the elevation is slightly higher more or to the east, south and west, which doesn't assist.
if the ppn is blowing in from the north east, that might assist, but Sevenoaks tends to do better 10 miles down the road.
