~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
