Under the Feb 09 set up, here in the hills of northern Cardiff we had 12inches of snow and in places 2ft drifts. The SW/s.wales got the heaviest snow fall amounts in the U.K. So totaly agree, you only want a rain band pushing up from the Atlantic meeting the cold east winds and bang, snow storm, i can remember feb 2009 well, im 15 and ive never seen anything like it, it was comeing down thicker than id seen it come down in New England, USA.
