I agree with what you say about op models. I can't speak for anyone but me, but this is the south. I always look for the fly in the ointment and it's usually there. When it comes to winterstorms I usually ride the warmest least snowy model because it's usually right. As far as pattern changes I'll believe it when it actually happens. Especially the phantom NAO that always shows up never to materialize. I'm hoping the MJO is not the fly in the ointment now. When it was last in the warm phases and forecast to hit 7 and 8 it took awhile for the ensembles to show it. They had an endless torch and gradually went to colder. Now it's the opposite and I'm hoping the ensembles don't start backing away on any cold pattern once they recognize the MJO in the warm phases. But as I said, that's just me. I'm not a pro by any means. I just look for what can go wrong because it usually does down here.
