Snow and Ice in the Northern Hemisphere 2013/14

[LincolnSnowstorm]

Looks like the first proper dumping of snow in the USA, the rockies and the Northern Plain states of Nebraska and South/North Dakota covered.

WINTER STORM ATLAS in the USA dumping LOTS of SNOW<br />http://www.weather.com/news/weather-winter/winter-storm-atlas-forecast-20131001<br />

The first live sub -20c 850hpa air for 4 and a half months in the Northern Hemisphere, here we go...

And it looks like much of Scandinavia could see its first (albeit weak) arctic outbreak by d5.

Doesn't appear to be any sport of PV forming just yet...At least, nothing that would signal a winters death for us.

[smithyweather]

oh my goodness I didn't realise how cold Iceland was. I guess I am not that far away from the cold.

Winter Storm Atlas looks nasty. A lot of snow so early in the season. Watch these videos. 

Doesn't look like the snow will last long though: http://www.wunderground.com/weather-forecast/US/WY/Casper.html back to 20c by Tuesday! The extremes of the American weather.

I can see -16c where is the -20c in the 2nd map ?? or is it just not labelled ?

I just posted this in the Arctic refreeze thread, but thought some might find it of use here.

 

Just looking at the IJIS sea ice extent, the average daily increase over the last 10 days (72,946km2/day) is the 4th highest since 2002, behind 2002 (109,556km2/day), 2010 (80,565km2/day) and 2008 (73,377km2/day), but higher than the 80s, 90s and 00s average.

 

With the NSIDC October data, it's interesting to see the clear increase in October sea ice gains over the satellite record, which ties in with the minimum extent dropping faster than the maximum extent.

It's there, but not labeled.

[keithlucky]

Much better snow cover than this time last year

Much better snow cover than this time last year

not bad, and last year was considered good.

It is the small light purple in NE Greenland... but no need to look as the 12z reading shows that the cold is most certainly back...

Surely you would expect this as much of the early re freeze in recent years is in areas which remained ice bound (or 15% re IJIS) at the end of say the 1980s min ice extent season.

 

However I'm sure the 100% sceptics will find the graph useful

Yep, it's completely expected, as I said, tied in with the minima dropping faster than the maxima. Interesting to me how clear that trend is. 

 

Not sure what your 100% sceptics bit is about?

[BLAST FROM THE PAST]

Snowcover at this early stage is looking good then, long may it continue as that'll be one bit of the jigsaw in place.

interesting to c the extent of the snow cover so far long may it continue. Correct me if i got this wrong but going by the latest model outputs surely high parts of scotland could c something wintery by the end of the week.

[sebastiaan1973]

not bad, and last year was considered good.

Last year, at 5 october, the situation was not that good. At least if you take in account the actual snowcover vs normal snowcover. Later on in the month the situation became much line with the current situation; large positive anomaly.First chart situation 5 october 2012, second 27 october 2012.

[bobbydog]

for future reference, here's previous years' snowcover by the end of october.

i started at 2007 as that was the 'lowest sea ice' year

 

2007

 

2008

 

2009

 

2010

 

2011

 

2012

 

 

but look where we are now-

 

and its still only the 6th.......

[smithyweather]

But it will be hard to expand any further west due to the mild air.

[bobbydog]

for now maybe but as we progress through october it will get colder in eastern europe and scandi.

we could potentially match any previous year by as early as mid-month

[bluearmy]

But it will be hard to expand any further west due to the mild air.

 

it will come further west over the next 10 days as a cold trough digs into central russia. it may well approach eastern scandi.  however, being so early in october, the chances of less cold air then causing a melt are considerable.

[smithyweather]

Hmm well tbh it seems as though some of the snow has melted in Western Russia.

which is what my post was trying to say re its last sentence ...................

 

the colder troughing is a week away, not current.
