Snow And Ice In The Northern Hemisphere 2012/13

[LincolnSnowstorm]

Haha you didn't rise to it, the snow's gone for now, temperatures are up to 5°c today. Good webcam btw.

No worries it will be back soon http://www.yr.no/place/Norway/Svalbard/Longyearbyen/long.html

Yesterdays and today's. Again, if you view them in separate tabs, it's easier to see the difference. As metioned above, HUGE increase in Ice extent. Siberian snow gaining again.

The holes in the snow cover are doing us no favours, we need to fill them in.

There is a lack of snow

But a big build up of cold must be nearly as helpful?

http://www.weather-f...none&type=lapse So a win win situation I think.

Lots of snow coming to the alps in the next 4-5 days

But, the positive anomalies are south of the negative ones, so does that mean the cold air is already being shunted alot further south than it should be?

That is the main thing I'm taking from this.

That seems logical. The further south cold air is, the better the prospects for the winter I believe.

Whilst those attachments are welcome, I bring to everyone's attention, the following animation (which I think updates daily). All credit to Bobbydog, who posted it up the other day.

As they are welcome here are two more for a quick glance at all the extra ice and snow!

Can not see yet but Norway must of gone negative to positive in one day. more on the way? http://www.weather.com/weather/tenday/+Norway+NOXX0109

Here is two examples of positive snow below negative ,to support that idea.

Another good thing about that Wednesday update is the additional snowcover over Scandinavia, let's hope it stays that way for a while.

[LincolnSnowstorm]

The ice must of over achieved on its rightside yesterday and did a little reverse on the latest map, that little spike looked a little odd!

i think this 31 day snow loop is the best way to view recent snow and ice.

there's lots of talk of 'massive gains' here but actually there's not. if you view the animation, you will notice a loss of ice at the start. that's because at the start, it is still in the melting phase. we are only half way through autumn and the growth will only just get properly started as of the next week or so. remember- its the ever decreasing sunlight which causes the rapid cooling.

the good news is, that the PV is consistently shown to move into the siberian side of the arctic in the last third of the month. if it does. then we should see some decent growth. maybe then (hopefully) we'll see what massive growth really means!!

[LincolnSnowstorm]

The Euroasia snow cover has doubled in a few days so to some keen observers that would count as a massive increase and I would agree but like you say it's early days and so I'm waiting for the really big increase that may happen as the sun sets on the northern hemisphere. About the animation v pics If someone describes something on a map you refer back to it without straining your eyes looking at up to 31 days at a time , good once or twice but not relaxing to look at all the time, maybe it's just my preference.

you can stop the animation and advance it one frame at a time.

and even choose which days to show or hide so here the link again http://www.natice.no...a-1mo-loop.html (to be repeated reguarly so new members and new guests donot miss out)

see post #422 as to why its not cool to just post a before and after attachments.

Snow has come to Southern Norway negative to positive amount in one day!

Good to see Scandi snow cover boosted!

Closer to Scotland now ,can't be bad

[Gavin Hannah]

We just need the snow to move west as soon as possible now.

Hi,

I thought I'd attempt an update to my post of 1st October with a forecast of sorts, for the middle third of October and beyond into fantasy island***

I will again use the GFS 12z ensembles for consistency. As ever, you should note the following guidance.

*Note in each case, strictly, we require the mean (red line) to sit consistently well below the 0 (zero) reading and down into the negative figures, in order to assume a decent probability of snowfall in the affected regions.

In each case listed below, the first attached chart, refers to the period from the 1st - 17th. Thereafter, the updated charts are linked.

Firstly, Moscow didn't appear that promising with regard to snowfall, what of now. To me, it looks like a bit colder than was anticipated, but a mix of rain and snow is the best on offer for now. However, I do feel there is a fair signal (>60%) of a sub freezing end to the run, i.e. nearer the final five days of October.

The projected t850 output for Helsinki is currently slightly cooler than was expected at this stage and to me, the forecast is reasonable with higher pressure, hopefully looking to dominate.

The Reyjavic 850s have turned out as expected for current time, but for now, it looks too warm for snow to be in the forecasts.

I hope the above assists you all into the expectancy of the next couple of weeks, for three specific locations due East, Northeast and Northwest respectively.

*** I would suggest that Fantasy Island is currently suggested to lie within t+120 to t+144 (16th/17th October)

Ta gives an good rough overview of these places in the near future.

[LincolnSnowstorm]

Chart seems to show a slow down in Siberian snowfall and an increase in high pressure leading to cold. So less snowfall with more cold for now and then some more snow, some of it farther to the west than before in the 3 to 5 day range.

Barrow Sea Ice Webcam

Barrow looking much icier and snowier now as well Is that ice forming on the coast? or strong waves

The NSIDC daily map is again showing an ice bridge from the coast of Finland to Estonia in the Baltic sea. Having been there 2 days ago this simply isn't true and neither will it be true for a long time yet. Any theories why as it did the same last year?

Hi Yido I've seen it show a faint outline around the uk as well, and we don't have sea ice round us ever some kind of glitch? makes you wonder how accurate some of the other pixels are.

SST'S in that area are currently in the low teens at moment so way to warm for ice yet

You can see misreported ice on the latest update as well.
