 Poster: A snowHead

Folks, is there any way to fix the fact that the first chart up here is current (i.e. today's), rather than as it was on 4/4/06 when carled posted it, and when brian commented on the "outlying blue line"?
So I guess that's a 2 part question: is there anywhere to get the 00z from 04/04/2006? can an admin swap it in for the one that's there?
If not, perhaps an admin could edit the posts which refer to the now-gone chart to indicate that one shouldn't tear one's hair out looking for the outlying blue line...
Actually.... hang on.... today's 12z is actually much more consistent with the text than the first time I looked at this thread. At a pinch we could use that...

There is a new snow accumulationl chart from the German Met Office. This will give a good indication of snow for next 72 hrs at 10km horizontal resolution.
http://www.wetterzentrale.de/topkarten/ani/wrf/
select 3h-neuschnee and gesamt-neuschnee (which are 3hr snow accumulation and total accumulation from the model start time(normally last midnight or midday)) Note that the scales are NOT the same and are in cm.
My last look has over a meter of snow in the next 3 days for parts of Switzerland.

Why does - as seems to be the case currently, by several degrees - the GFS thick green temperature line often not line up with the other models, even when the correlation of the other models is extremely tight. And I don't mean fantasy island, i mean the prediction for later today!

Well to my inexpert eye it looks as though all bets are off after the 12th. You could read whatever you want into those ensembles.

The ensembles rarely seem to show trends that would appear to show the expected (by me) variation between day and night. Is there a reason or is the differentiation there and just not as obvious as I'd expect?

ishay, I would have said in most of the graphs it DOES indicate day vs night. Maybe it's more prominent in the non winter days?
The peaks and troughs can be seen on this example:

Hmmm, well yeah it certainly looks like it on that chart!
I've been watching this one though for Northern Italy and it is much less obvious (and always seems to be so)

Local conditions? But then I've been going here for 3 years and I know it certainly does drop, a lot, at night

The TWO spin off site IcyBlasts now offers 16 day probability forecasts in addition to the deterministic ones. My view is these provide a better guide to the medium term weather prospects despite these being set at regional rather than resort level. The plots shows 850hPa temperatures, precipitation amounts, the 'snow row' (number of runs in the suite forecasting snow) and the surface level temperature spread.
The probability forecasts can be viewed by using the resort picker and then selecting probability:

I am, on the whole, a not too dim bloke, but the GFS charts are leaving me totally dark? Are the wiggly lines across the centre the 'ensemble'; being a collection of available chicken-bone predictions? Do we snowies get excited when they are close to being a fat corridor across the page, rather than a spider's web all disagreeing? If yes-ish (well done me!)... what's the bottom row of lines telling me? And what are the 'P' numbers on the y axis?
I have tried to follow the explanations, honest!

Both are Interactive Weather Forecasts that show forecasts for GFS, GEM, EC. Lots of things to play with for those who don't wish to use ensembles or other maps or as a companion to these. Enjoy.

No it's not! Where do we go for the GFSs now? (Thanks for the years of service BTW!)

If I can I'll find an easy alternative for you all.
Is it the live links that were most useful or the point in time grabs?

Can anyone help me find a graph for les arcs please. I think I’ve managed to get my head around reading them but the amount of options when creating them seems to baffle me. Thanks

Fed up of navigating Wetterzentrale on my phone, I created a little html/javascript page to give me quick access to the data I want about the places I'm interested in. It looks like this:
You can get it from https://drive.google.com/file/d/1LpSHY6pPpdYlC49EgO_u0wzm2VCWrDLE/view?usp=sharing
Save a copy locally on your device and open it from the file manager. You can extend the list of locations by adding a new line to the obvious list of locations.
Change the value attribute to that for the required location, you can get that from Wetterzentrale on the end of the url for your target location, e.g. for Whistler it's 10422:
https://www.wetterzentrale.de/en/show_diagrams.php?model=gfs&lid=OP&var=93&bw=1&geoid=10422
The chart types are those I've found most useful for forecasting snow, there are others you could add if you want.
One oddity of the WZ output is that if you select a model run that is in the future it will give you yesterday's chart dated today.
Hope this is helpful to someone.

FAQ
First time a post on this thread has made sense to me, despite trying and failing to decipher the graphs multiple times.
