Before I go there this weekend I only want to enjoy the snow (not going skiing) is it open even though it’ll be snowing? also would I need chains for my car?

Yes, the resort will be open despite the snow storm. Yes, chains or 4x4 will most likely be needed Saturday though probably not Sunday and Monday. Please see here for current road conditions. http://www.mthigh.com/site/trails-and-conditions/conditions/road-conditions1.html

Always open. Carry chains with you as a safety precaution.
