Are events cancelled in the event of rain? How does one find out if an event if cancelled?

If it is raining, events are usually cancelled (it is an open air facility). I believe the decision on that usually comes from the Frederick Council for the Arts.

Most of the time. Yes. You have to find out through the person or company the organize the event. Through Facebook Local events app. Also, through Sky stage Facebook page they have events the will be happening throught the year and posting updates through their page. Hope this help!
