Wasnt meant to be patronising but if you are studying Meteorology am guessing at UEA then surely you could see the Low Pressure was losing intensity (Dan calls it Upper Forcing) then you could see that the Northern Extent of the Precip was struggling and with no heavy precip at 36f dewpoints it simply wasnt going to fall as snow, as the precip shield has waxed and waned away moving out towards the east when the favourable conditions (EG Dp's around freezing were there) the precip wasnt strong enough for the Norfolk area.
I always like to go through the event after it has happened to try and see why things happened and why things never happened and wrote a paper on the infamous 2009 Snow Event that many Met Students have asked to do studies on (That event was triggered by an Inversion around the Norfolk, Suffolk and Essex Coasts) that stopped the Snow from reaching the ground other than polystyrene balls with cloud tops at 37,000ft and Uppers of -14. The same Convective storms moved from the ENE to WSW and gave over a foot of snow to London.
Its all a learning process, was not meant to be patronising in any way
