Weather? Sure, but in concert with extreme negative anomaly.
This is daytime max at Kangerlussuaq. The warm event lasted from 1 to 11 April:
For this decade nothing alike to be found back to 2006.
MODIS shows snow cover most hit near the icesheet boundary. On the coast the effect was smaller.
It is not of ‘climate-consequence’… a minor, regional event. But if this is capable of producing about 2 km3 calving on Sermeq Kujalleq this early in the season, lets hope June/July doesn’t show comparable circumstances.
BTW weather is in for a decade of freeze over there now. Circulation changed…
