~A large water anomaly in the Greenland to Pole sector may cause even more exodus of sea ice
~2 nautical miles a day is about the average flow of sea ice, with open water about this speed easily can be multiplied quite a lot.
~83 North 8 West open water anomaly just had 20 km displacement in 2 days 3 times the normal speed:

~ The speediest melt rate since 2012 and 16 slowed by weather dynamics is not quite finished surprising yet
~The current latest melting appears innocuous but is huge

~This loop offers an explanation of the warm High over the Arctic Ocean, sea ice on the Russian side of the Pole is much thinned.
Laptev sea ice melt speeds continue to impress, at right we have astounding example, usually sea ice melts when the ice pack is scattered, and pans of ice are prey to surrounding warm surface water. Not in this case, sea ice is melting from within the pack. The loop sequence below captured the jutting ice pack at centre (right);

~The only reason possible is warmer sea temperatures and thinner sea ice
may contribute to a stable High on the Pacific side of the North Pole quadrant, this I did see coming but only for a short time, not as long as a week or 2. It is a disaster for sea ice:
Given that the Atlantic front has collapsed, the flow of mainly pack sea ice will be dumped at a monstrous rate, especially with the North Atlantic Low ideally located. The CMC July 8 surface map also depicts something not common,
it is a cold surface High over sea ice, but very warm High aloft. It means an upper air heat source. The origins of this more than one week old anticyclone are equally interesting.....
....... It simply appeared (U. of Wyoming), on June 30 past. Likely formed in part by the flow of North Russian Urals hot air pumped by a similar if not the same Low pressure vicinity Novaya Zemlya.
This warm aloft High seems quite stable. A disaster for sea ice is in the making.... WD July 8 2020

~A sudden apparently surface wind easily broke up a once consolidated multi-year sea ice with ease

~It is broken up , ready to move anywhere, at the winds whim
The survival of 2020 sea ice is rather precarious at this moment. WD June 24,2020

~Arctic Goodbye waves, seen here: http://eh2r.blogspot.com/2016/09/wrangel-bridge-waves-away-goodbye.html , are a terribly photogenic, even artistic expressions from sea ice melting away.
~But Jupiter is no Earth. Or is there solids on top of its dense gaseous atmosphere?
here. Something on Jupiter looks familiar? EH2r has dealt with this before:

~2019-2020 was a winter with lots of snow
~Most of it gone where it should have been remaining, that is if you look at surface temperatures and sea ice extent numbers.
~The mystery white mask of 2020 season is melting/sublimating away
The first thing we remember about 2012 sea ice melt season, was the cyclone over the Arctic Ocean on August 5. But 2012 was also a year with a more normal snow cover as opposed to 2020.
The thing about Arctic snow over ice and land is that it is spread out quite evenly by the winds which may span in the same direction for hundreds of Kilometres. 2020 spread out was more important, by about a factor of 2 compared to 2012. So you might think, 2012, the year with greatest sea ice melt on record should show more land than any other known year at an early melt season date, say June 3:

Annual spring-summer-autumn Northern Hemisphere weather projections , by the usual unorthodox methods .... A preview
~ENSO high cloud symptoms gave varying signals for the 3rd year in a row, again no plunging towards deep La-Nina is foreseen.
with super warming of the continents, the North Pacific SST warming is not too strong by slower drifting Lows, because at July end, the Vortex should not be strong at all.
ZETA GRAPH. The stratospheric ozone hole of 2020 reinforced the said surface cooling over the Arctic Ocean of March 2020, or is it vice versa? Nevertheless, the tropopause was hard to distinguish during much of March above Cornwallis Island Nunavut Canada, Upper air profiles in the troposphere had often much stronger than usual adiabatic profiles, while the average said profiles between 2008 and 19 were much more stable and warmer. In here lies the contradiction, what fueled the more unstable adiabats in 2020? I suggest it was largely thinner sea ice, prevalent everywhere throughout the Arctic, as presented on my previous article, 925 mb level Arctic temperatures were warmest ever..... Temperatures of the 1 to 3 kilometer greater in height tropopause of 2020 was often -80 C, an ideal temperature for atmospheric ozone depletions. This greater height of tropopause is reminiscent of 2011, which had many destructive tornadoes. The dissipation of the stratospheric polar vortex very strong center will not relinquish its winds overnight. Therefore the strong possibility of 2011'sh tornadoes, but likely further Northwards than usual. WD April 21, 24 2020

2020 Lower Polar Vortex shrank by 8.5 million square kilometers compared to 2012 , 2020 has smallest area every year since
~ Even compared to 2016, El-Nino driven warmest year in history
~It is unquestionably clear, warming at the core of the vortex is from over all thinner sea ice

Meantime, your wet soggy weather can be largely attributed to Omicron pattern whipping ocean air straight onto the Western continental coasts, as opposed to 8 shapes seasons diverting the Eastern oceans moistures and warmth Northwards. Early prognosis for 2020: hope you the enjoy more rain if you are East and West coasters, the Ying and Yang of moisture, mainly a consistent Pacific flow joining the Atlantic Gulf stream making dry spots only within central continents ....

~First observed in spring 2017 by refraction sun disk method
~A surrounded shrunken by greater heat Polar Vortex gives deeply cold vortices.
December 31 2019, with Polar Vortex off center weighted temperature measuring -48 C CTNP over Ellesmere Island, the coldest such air ever measured for this date, surpassing all others by 4 degrees C (1948-2018).
