Problem with snowforecast .com is that, even though it uses GFS data, it appears to bear no resemblance to the GFS precip data on the operational run. Its almost as though it appears to be using an ensemble mean, if that is possible - and if it is, then that is not going to work for precip / snowfall. In the past (a few years ago) I always found it overestimated snowfall, however, there must have been some tweaks, as this season the opposite is the case and it bears no resemblance to reality (and I have been keeping a very close eye on all the forecasts for this part of France on our chatelweb.com website!) edit - I agree re. precip forecasts for the Alps - especially more than 48 hrs away - it is virtually impossible to pinpoint amounts with any accuracy - however that Euro4 is good once its in range.
