SNOW & ICE coverage in the Northern Hemisphere 2016/17

Given the current setup, why is Scotland (the highlands) not cold enough for snowfall on the mountains?? This perplexes me....

Not cold enough is the obvious answer ;-) Seriously though, it probably is cold enough for sleet, but snow is pushing it. It's mid October after all...

Couldn't have a different set of images than these two comparing this year (Top) and 2015 (below) 

In 2015 we had this sudden surge west but the build up in North Russia was far less. As I remember most of this westerly surge melted back a week or so later so while it was a startling development so early in October it really built some false hope for a good snowy winter. Personally I think the growth is nice this year, not too fast, no enigmatic sudden growth to get excited about but instead consistent build up in the right areas for the time of year.

A much better pattern thus far with more snow south of 60N.

Yes, those 2015 charts indeed show a hint of "peaked too early". What to make of this year, I'll that to others to give us some insight on. As ever I'll get all the more excited about thinking the UK's snowy prospects come the second week of November onwards. Tis odd, though, how stubbornly the Easterly winds have persisted and so early in the season as well. Kind of reminiscent of 2013's early Octobers' snow-infested Easterlies in the US which devasted a lot of farming practices over there due to the early snowfalls. An interesting watch once again.

Lots of snow on the eastern seaboard of the US / Canada. Alaska is lagging. The synoptics are totally different to last year and that's a good sign that we may get a decent season this year (if we were simply to compare previous years snowfall accumulations & locations).

Looks like Arctic sea ice is making rapid gains after a long pause (at least visually), think graphs will confirm.

Huge snowfall in Scandinavia over the weekend. Also, big increase in the ice-cap - looks like it's touching Siberia?? 

Many a pixel for Scotland tomorrow if the METO is correct? :cold:

The 'hole' in the main snowfield should be filled today, so tomorrow should look even more impressive. Then the trough you mention comes into play and should push more snow south and west.

This is very good news. Actually, the news I've been waiting for...about snow in Scandi.

There's a theory that snowfall in Scandi in October and then the rapid melting of it can lead to -AO during the Winter and may lead North West Europe into the freezer.

It occured in 2009, 2010 and 2012. :cold:

I watch with bated brethe... :clap:

Consider it filled.

Along with a bit more in Scandinavia and most of western Canada. Alaska still staying stubbornly snow free though, mostly.

It just seems to stop at the border with the Yukon.

Most of Canada full stop! Great to see, and that vital cover south of 60 degrees is looking good along with that nice patch in the Carpathians in Romania too, things are proceeding nicely in the Tatra mountains as well.
