Greenland ice sheet ablation area albedo above average, upper elevations below average

A delayed melting at low elevations and probably some summer snowfall blanketing the Greenland ice sheet ablation area with (highly reflective) fresh snow have resulted in an important slow down of Greenland melting. This pattern is in contrast to this time last year (in 2012) when record melting was emerging.

    It is quite different from 2012. But is in the process of the melt ramping up quite a bit. I also doubt it catches 2012. I feel about 99% sure of that. The one percent is reserved for the possibility of wild weather , maybe some epic August torch. You never know. But that is highly unlikely.

    In the mean time. Global models show the warmest conditions of the melt season so far about to invade GIS. Not from the major -NAO pattern but a mesh of different changeable schemes. The NAO is forecasted to quickly drop to around 0.

    It appears heat in the North Atlantic in the water with above normal SSTs and very little to no Sea Ice East of GIS if you go south of about 70N. SSTs in the Baffin Bay have also started to warm a bit.

    I would say by the 9th. We will see albedo levels start to really drop over the SW, South, and SE portions of GIS. Still it doesn’t appear to get anywhere near the 2012 neighborhood. Even though the GFS does forecast back to back days with 850s mb temps reaching almost 10C over Central GIS(just south of the Summit.) This will probably spike the NSIDC melt area chart.
