I am not going to be too critical, as you have put a huge amount of effort into this, but I want to give you, as a surfer, snowboarder and Oceanographer some ideas to make this a little easier on the eye for a lay person whilst not committing you to such a dedicated predictive service which may backfire?!

Why not try to teach people how to make their own interpretations from QUALITY LIVE pressure data, not scientific speculation! Surely thats the key……. Long term is always unreliable when looking at such small microclimates, over such small periods of time as a winter season. The Mont Blanc region, typifies an unpredictable region from the models you are using, especially when the elevation is not taken into account on many of the charts you have used. Snow storms caused from uprising moist westerly air can be forced into mountain walls to rise and then cool very quickly, to hopefully collide with cold high pressure air systems, this creates snow. It depends on direction of low pressure assault around the mountain setting you want to look at. Remember that snow fronts are only ever 20 to 50 miles acrross and form a crest on a low pressure system as it collides with another body of air, so can be quite fickle. Hence, just over the way in Italy, last season, they had great snow when Cham. and other French areas struggled…..
