Hardly any pictures of the latest snow cover, anyone?

Ignore the squiggle in the line which was some kind of error most likely related to the recent outages, but as you can see across Eurasia as a whole very positive in terms of cover and the gradient looks pretty useful too.

Plenty of discussion over on the AmericanWX forums about the SAI holding up close to 2009 and 2012 levels, guess we will have to wait for a final report in a few days time.

Thanks for the link, Buzzing on there (and we begin) Looks like the Eurasia chart  is about a month ahead of the worst and well ahead of most years, will be interesting to see what effect it has. Big gains as they happened shown as red http://www.daculaweather.com/4_sample_loop2.php

What would lead for some  to 3:12 onwards!  http://www.youtube.com/watch?v=p6Eaz-1_3iA

Cohen is going to get a good workout this season, these figures are looking very healthy now added in 2014 on the chart just to highlight the cover vs previous yrs in the series.

 

 

Great thread on amwx on the subject with some dedicated calculation of potential msk figures. The 1976 analog just posted is superb.

IF NOAA cannot keep track of snow depth the Canadians can https://www.ccin.ca/home/ccw/snow/current

Its a shame the +5cm to -5cm departure is one big grey area but thanks for the link.

 

Edit. lots of green showing

Really useful graph from CFBaggett over on the AmWx forums, showing essentially the state of the SAI thus far. Remember it is the gradient we are focussed on, and it looks to be up there with (if not slightly exceeding) 2009 and 2012.

Worth noting there was some very large meltback yesterday across Scandinavia and E Europe, but also some gains further South in to Kazakhstan and southwards. And in all honesty at this late stage of the month, other than anecdotally, I do not envisage it having a huge effect on the processes related to the SAI.

The snow in Svalbard might take a bit of a pounding in the next few days, particularly further south, before it turns colder again next week.

 

The warmer weather caused a thaw at lower levels as expected. Colder weather with snow showers returned in the last couple of days though Longyearbyen is still looking bare - http://longyearbyen.kystnor.no/

Looks like showers are around and it's murky to the east where the feed from this web cam in Adventdalen shows snow falling live for those who need a fix - http://adventdalencam.unis.no/view/index.shtml

 

edit: Incidentally the winter night began for Svalbard a couple of days ago with the sun below the horizon, but there is still plenty of twilight during the day at the moment.

Admittedly it's at a high elevation, but I often use Norway's highest railway station, Finse, to keep an eye on Scandinavia's snow situation, especially for more southerly locations where altitude really counts during the autumn months. Also it is rather fun to watch the snow fall - http://www.finse1222.no/en/webcam

 

I should point out that there was virtually no snow yesterday afternoon.

Glorious.

 

Technically i think the highest correlation is actually with the 23rd September-22nd October anyway.

Is there a source for those dates? I have seen different posters giving different dates.

I read it was analysis on Americanwx, no idea which thread. But the correlation was marginally higher from the last week of September rather than the first week of October.

That works for us as during this period was the biggest increase.

There is a surplus 'space' character at the end of the url in the link, delete this and it works

We had a huge melt back in 2013, we might see something similar this year although it will still put us ahead.

According to the creator of this graphic, Rutger, the SAI 2014 will be around 2,4. Significant higher than 2009 and 2012 with 1,5-7. Amazing!.
