Melt a new maximum for the year by a substantial amount.
Precipitation not as high as the last 2 days, all in the SE quadrant, partially counteracting very high melt and as a result
SMB (Surface Mass Balance) loss spectacularly above average.
______________________________________________________
GFS OutlookMelt / Temperatures. are looking much above average for the next few days.
Precipitation 5 day outlook.
All of Greenland looking very dry or bone dry. This could mean that SMB loss will be as high as July 30 & July 31 as lower melt more than offset by no precipitation.
It will be interesting to see how much the lower precipitation offsets the lower melt in the SMB gain / loss equation over the next few days.
High pressure has been, is, and will be stuck over Greenland until ....

Lots of question marks in the posts from the professionals on how the DMI model is dealing with precipitation and melting during this unusual temperature spike. I wonder if the model's parameters can properly deal with events so far outside "normal" limits.

Most of the time it is very quiet on this thread - but at the moment..........
Mind you, I still say that it is the
persistently above average or very much above average melt since June 10 that is more significant for the overall SMB this year than a two / three day event such as this.
My evidence is the melting graph and the SMB graph.
