Mate, the weather is ALWAYS a factor, whether or not youre MECIR. For a young inexperienced PPL it would make it an even bigger factor because you'll be tempted to go when perhaps you shouldnt.
PPL+IR+light twins+dodgy wx=very uncertain result.
Take it easy mate, learn to fly, do a CPL and have think about an IR if you think you'll do enough to keep current after that.
