Melt up a bit
Precipitation much higher, all in the SE quadrant, overwhelming slightly higher melt and as a result
SMB (Surface Mass Balance) much below average.

GFS Outlook
Precipitation 5 day outlook. Greenland North & West very dry for the next 5 days. Precipitation, that could be high, pushing in from the Atlantic towards the east coast - looking like rain at lower altitudes.
Melt / Temperatures.
For once a predicted major weather event looks inevitable. Spike in temperatures starting today (Monday), reaching extreme highs on Tuesday & Wednesday, and staying much above average to perhaps Saturday. Nearly all of Greenland will get some melt at some time over the next 5 days - and in some low altitude places extreme melt for long periods.
It will be interesting to see how much the higher precipitation offsets the higher melt in the SMB gain / loss equation. And how does the DMI model deal with precipitation falling as rain in lower altitudes?
_______________________________________________
The Accumulated SMB Anomaly map shows the extreme contrast between the SE coast and the West coast. In theory, the DMI model should show the SMB gains and losses by drainage basins. GRACE-FO data is also by drainage basins.
If the drainage basins used are the same (!?), and if IceSat drainage basins are the same (!?), measurements of mass loss / gain from calving, melt and precipitation and consequential topographical change by Greenland's individual drainage basins would be possible.

High pressure has been, is, and will be stuck over Greenland until ....?
Part of a major weather change in the whole Arctic Basin?
