Belleayre has a pretty good webcam that you can remotely control. The trail count is reasonably high at Belleayre as of today, and the weather looks good for snowmaking through next weekend for at least a few days. Not sure about Windham. Good luck at the races.
Windham was pretty thin yesterday. There were a reasonable number of trails, but they were all loose/frozen granular WROD. Very few were full width. Why Not was open and looked good enough for racing, but I think they moved the GS course from there a few years ago. The race training trail (Race Factory?)was grass. DO you know where the GS course is?
IF the weather is good for snowmaking, it will be fine. Otherwise...
