Maybe the recent hurricane force winds up there have something to do with the alleged "slowdown" Doc?

Hi Jeffrey,
If it's action you're after there's lots going on over at the companion Arctic Sea Ice Forum:
https://forum.arctic-sea-ice.net/index.php/board,3.0.html
Failing that here's my own analysis of the early days of the 2020 melting season:

Things do not look good good for ice retention at present.
Albedo reduction across much of the CAB has already started

Intriguing "unorthodox methods" Wayne!
In slightly more orthodox fashion, my alter ego's latest reanalysed "measured" Arctic sea ice volume numbers have just been released:
http://GreatWhiteCon.info/2020/03/facts-about-the-arctic-in-april-2020/#Apr-25
It now seems certain that the CryoSat-2/SMOS Arctic sea ice volume maximum was 18469 km³ on April 6th

OK AJ,
When I have a spare 5 minutes I'll prepare a "spring" NWP graph, although personally I reckon a different combination of areas would be more enlightening at this point in the "melting season".
However that won't happen for quite some time. On top of everything else I'm currently preparing an in depth report on a determined arsonist who has no qualms about exterminating large numbers of defenceless wildlife in my very own parish:

Neven's OK, but the ASIF seems to be down again just at the moment?
Meanwhile the March PIOMAS numbers have been released:
http://GreatWhiteCon.info/2020/03/facts-about-the-arctic-in-april-2020/#Apr-04
The PIOMAS "modelled" numbers put volume at the end of March as 7th lowest. However CryoSat-2 "measured" thickness paints a rather different picture. Compare and contrast:

AJbT - Quoting the NSIDC:
Seasonal snow is an important part of Earth's climate system.
Snow's albedo, or how much sunlight it reflects back into the atmosphere, is very high, reflecting 80 to 90 percent of the incoming sunlight. By contrast, trees, plants, and soil reflect only 10 to 30 percent of sunlight. Snow cover wields the largest influence during springtime (April to May) in the Northern Hemisphere, when days become longer and the amount of sunshine increases over snow-covered areas.

I emailed Neven about the problem earlier in the day, but currently (16:50 UTC) the ASIF still seems to be down.

Thanks for the heads up William,
Fat finger trouble on "Snow White's" part! I'll endeavour to fix it.
Meanwhile "she" is already speculating about the forthcoming maximum metric season:

Thanks Wayne,
I'll pass that on to Judah Cohen!

The PIOMAS numbers for January have been released, including the gridded thickness maps from the wondrous Wipneus:
http://GreatWhiteCon.info/2020/01/wheres-the-thickest-arctic-sea-ice-gone/#Feb-04
Thus far this winter the polar vortex has been remarkably well behaved. By and large cold air air has stayed in the Arctic. There hasn’t been much in the way of cold air intrusions into mid latitudes or warm air intrusions into the Arctic.
Hence it’s not at all surprising that the thickness of sea ice in the Arctic has been increasing slightly more quickly this winter than in other recent years.

Hi AJbT,
I doubt that! My better half and I were confined to bed with "the flu" over Xmas. We had emerged by New Year's Eve, but didn't feel up to attending the village knees up next door.
I'm still coughing and spluttering somewhat, but I'm ensconced back at my keyboard just in time to reenter the Climateball™ arena at an opportune moment:
https://twitter.com/njbtweet/status/1222660599475138560
As for Arctic temperatures, scroll up to read Wayne's report and/or wait and see what Judah Cohen makes of this:
https://twitter.com/jim_hunt/status/1222666724669100036
I'm going back to bed now (UTC)!

As anticipation builds for the next monthly release of PIOMAS data here are my own thoughts on the current state of Arctic sea ice thickness and hence volume:
http://GreatWhiteCon.info/2020/01/wheres-the-thickest-arctic-sea-ice-gone
Over the winter of 2018/19 ASCAT revealed that there was a relentless movement of multi-year ice towards both the North Atlantic and the Beaufort Sea. Perhaps a significant amount of the multi-year ice that survived the winter of 2018/19 has now simply melted away in warm water, to be replaced by much less robust first year ice in the area between the North Pole and the Siberian coast?"
Also Stefan Hendricks from AWI has been aiding the further development of a "citizen science" flavour of a "Near Real Time" Arctic sea ice volume metric:
