A first stop should be @WeatherToSki, which today is reporting the first small snowfalls ahead of the more comprehensive arrivals expected over the coming week. It's a good source of information more generally - take a look this piece on snow sure resorts near Geneva, for example. It includes a visit to La Balme, high above La Clusaz.

The MeteoFrance site has a special section on montagnes and goes into quite a bit of detail. And there is also LaChaineMeteo.
For Les Arcs, you need to be careful about whether you are getting a reading for Bourg Saint Maurice (810m) or from the actual resorts themselves - i.e. from 1600m upwards.
@SnowForecast is very good and enables you to target each resort. Or of course you can go straight to the weather section of the Les Arcs official site.
Back at home, you can keep in touch with Britain's latest snow news by following the @UKSnowUpdates or the ever-hopeful @LondonSnowWatch.
