It certainly fits in with the mean monthly sea-level pressure pattern
which shows high pressure in the Greenland/Iceland region, and
a positive anomaly centre of +5mbar over eastern Greenland.
(I'll provide a link in my synoptic review when I've uploaded the
relevant pages).

The ice east of Greenland is fed by ice from the Arctic Ocean moving SW in
the Greenland Current. Maybe that has been assisted by more northerlies
(or fewer SWlies) east of Greenland, associated with the anomaly you refer
to?
