Precipitation higher than average for a day or two
SMB gain for the year (from Sep 1) is and will probably stay very close to average or below.
The event did happen and is still happening, but fading away. precipitation above average, but not by that much, and some warmth but insufficient to move the melt graph off zero.
From now it looks like a lot of nothing is going to happen - Greenland staying very dry. That is, of course, significant, as conventional wisdom says that as temperatures rise, so does water vapour and precipitation increases in the high latitudes. But not in Greenland so far this year, a contrast with the previous 2 years.
Indeed, all of the snowy regions of the Northern hemisphere are now showing average to below average snow cover extent, which seems likely to continue (see attached image).
In a continuing facetious attempt to create drama I note that accumulated SMB from September 1 to date is continuing to follow the 2011-12 pattern - and look what happened in 2012 !!

SMB = Surface Mass Balance, which excludes mass loss from calving that on average is greater than SMB gain in the year. i.e. usually Greenland loses mass every year.
