east_sider, don't believe what you've been told about safety, not letting first solo students go up in conditions they can't handle and such. The only reason they do not let you go out on windy days is that you'll remember your first solo forever, and instructors know this. So they want the memory to be good. CAVOK and wind calm makes a perfect memory.
Sunday and Monday look good, at least where I am. Might be a bit windy though.
