Ref Aleman’s comparison maps. Just shows how little snow Southern, Western and even Central Europe gets these days away from the mountains. 

Compared to when?

Just seems to me that there is very little snow cover in Europe for this time of year in the last ten years. For example Poland down towards Hungary etc is nearly free of snow in most of those years shown. I don’t have equivalent maps from earlier decades but would like to see them to compare. For example from the sixties to the eighties. @Aleman Do you where I could find them?

Snow expected in Europe next week.

Snow cover has increased a little bit in parts of Sweden.

[Katrine Basso]

Sea ice has increased very slightly.

 

[Katrine Basso]

Still more gradual increases in the sea ice cover.

 More slight increases of sea ice cover.

[Katrine Basso]

Gradual increases in sea ice cover.  Increase for snow cover for Scotland, Ireland and North West England.

The sea ice is still increasing although at a very gradual pace.

 

[Katrine Basso]

The snow has come back to Scotland and there has also been more gradual increase in sea ice cover.

There have been few increases and decreases in ice cover.

Some interesting summary graphs here, It shows very average Northern Hemisphere snow extent over the 18/19 winter season but highlights the heavy snow depth through February that is now turning into a heavy melt season and causing floods in the US and Iran/Afghanistan.

2 feet of snow in South Dakota

Bonkers weather in North America. Most Alaskan snow has melted but it's currently snowing in 11 western states, with up to 20 inches predicted for Wyoming and 18 inches for Colorado.  Meanwhile, in Houston, it's 26C in the middle of the night!

Warmth around Alaska and NW Canada is showing up as early ice melt along the Arctic coast although there is some thick ice further along the Northwest passage. The Northeast Passage along northern Russia looks like it might open a bit earlier this year.

It looks to have been snowing quite a bit in the Himalayas this summer. It's been quiet in the Arctic this time, after regular snows through last summer. I see there is a bif of snow modelled for Siberia next week and then quite a big fall for Alaska, where it's been warm almost all year and hot recently. It might not happen but it looks like a new season is just around the corner.

[Aleman]

Good areas of settled snows across HImalayas and Siberia (more predicted), and tiny bits of Alaska and western Canada. The first signs of winter look to be early this year, although it's been warm in Nunavut this summer where they had lots of little snow showers last summer.

A few new Siberian pixels showing here, too.

Looks like there's actually been a little more settled july snow just above the US border along the coastal mountains and in the Rockies, and in Siberia. I found this article blaming an unusually rapid and cold jet stream.

A few more snow pixels for Siberia, Alaska and southern Canada Rockies. Can it stick so early?

The Northern Route/Northeast Passage is set to open to non-ice class sailing imminently, a week or so earlier than the recent average?The Northwest Passage looks borderline for opening, with about 5 or 6 weeks of melt season left. I'd guess it might do very briefly. Arctic sea ice extent and volumes look to be tracking at or near new seasonal lows.

Arctic sea ice extent is at record low sadly! https://nsidc.org/arcticseaicenews/charctic-interactive-sea-ice-graph/
