Turning around was probably a good decision. Others have already mentioned flight watch, too. Don't let the fact that ATC might not like something stop you from asking for it. If you're getting into a WX situation you're not comfortable with, ask ATC for a WX update. Doesn't matter if they like it or not, it's part of their job. Odds are the controller will be MUCH happier to hear you asking to keep tabs on the situation than just barelling through. It also gives him a heads up as to what you might be doing, be it turning around or landing somewhere close by. You might actually be surprised how helpful some controllers can be in this situation by not only giving you an update at your destination, but also giving you WX for other airports close by that might still be VFR.
