Arctic Ocean circulation Switchover occurred as expected in late April projection...

~Temperature is key ,  now Arctic Cyclones are colder than High pressures.

CMC June 12 2018,  with a High now over Baffin and a low over the Arctic Ocean Gyre,    in between is the CTNP vortex,   the pressure scene has SWITCHED ,  offering some hope for sea ice with extra cloud cover.

Further a study:

What separates the High from the Low is a cold upper air zone not measured in a significant density  grid manner.  700 mb temperature and pressure heights CMC June 12, 2018 1200 UTC.

   What remains is the possibility of an Arctic Dipole,  which is a rare event at this time of great melting.      The possibility is there but requires a High over Alaska which may venture North. Mean time we must judge how fragile sea ice is by its velocity:

       Impressive speeds of sea ice drift makes for a great melt,  it is fortunately the source of open water.  Fog and cloud source at near 0 C temperatures.    WD June 12, 2018
