I've cancelled a few times when wx was technically legal to fly, both as the Flight Lead and the OPS SUP said go, and as the OPS SUP when the Flight leads were willing to go. There have been plenty of times where it's much more prudent to not fly that day. Realize you may have to do some explaining, but I've never once been threatened with loss of quals. Even if I had, it wouldn't have changed my mind, especially for a daily CT line....lol make me a wingman only (twoop!). If you said you'd have to "report it to the DO," I'd say sure thing, let's walk down there right now....hell, get the SQ/CC and OG if you want, I don't really care. Once you've been a FL/AC/OPS SUP for a while, you start to learn what really matters and what doesn't. I'm all for going out and getting some good experience/lessons learned, but there are plenty of times where, even if the weather is technically legal, the gain does not outweigh the loss/potential risk. It gets even easier when you have the option to cancel and go fly that mission in a sim.
