for France, this is a good site:

Yes, that's what I usually check -- another URL for it is:
http://www.nordique-france.com
For XC ski centers associated with lift-served downhill resorts another
place to look is:
www.skiinfo.fr

Warning: Especially at this time of year, check the _date_ of the snow
report carefully. Some of the reports showing snow or open trails are
actually from last March or April.
