I agree with friv, and think one additional ingredient here is the amount of ice that will be sent down the death zone past Svalbard and out the Fram strait. We're looking at 4+ days of strong surface winds exporting ice. Just look at how packed the isobars are on this output and how well they are positioned to export ice.
That ain't no joke that is crazy you're going to see open water come in the kara or the laptev because of all this
Chiming in.
Add Ekman pumping. The ice is far more mobile than previous years, so it will not prevent transfer of force from the wind to the water below. We should see significant mixing of the column under those regions where the wind in this dipole are *already* at work. The CAB immediately north of Svalbard will be shattered more thoroughly than we would normally see before July.
The High combined with the storm over Svalbard create a near perfect hammer and anvil to shatter the Arctic. The only question remaining is just how severe the damage will be.
To underscore what Friv said earlier about albedo, we are talking about conditions being created (dropping albedo from 85 down to 60) which will more than double the amount of insolation being captured by the ice. It will be doing that about a month earlier than typical, during increasing insolation.
Certainly we've seen ice get beaten up with lowered albedo, but mostly that is happening after the solar peak in late June, so the ice is basically riding the end of a wave (diminishing insolation) after it's broken.
We may be about to see that equation shifted a full month, so that those late July conditions are reached in late June instead - at peak insolation. In short, the ice will be getting pulled into the "wave" of insolation just as it's breaking, with pretty serious consequences.
If that happens, it will be hard *not* to overtake the 2012 extent and area losses.
Absolutely nailed what is at stake attm.
Just browsing through Modis looking at when the majority of the Arctic basin went from dry/semi dry surface to wet by year.
With about 80 percent being the magic mark.

Notice not one year has May.
Why?
We have never had a basin wide sunny wall to wall ridge between 15th-30th of May.
The major ridging has appeared in early June.
It might be to early to see the surface albedo collapse.
And by the time this pattern changes we might be already to early to have made a basin wide dent.
However from the pole to the Chuchki, ESS, laptev, Kara, and Atlantic side will see albedo drop from this.
The question is how far well that penetrate towards the CAB.
Imagine if this pattern evolves into a dipole anomaly the last week of May that holds 2007 style into deep June.
That is how we have a basin wide collapse of the remaining ice structure.
