I assume that you're referring to the ability to predict weather conditions a month or more in advance, and not to predictions of future weather trends like with GCM models or changes in ASHRAE design conditions, etc. If so, then I would say the answer is "no". All the advances in climate forecasting models are good only for the next few days or a week at most. In fact, I recall reading a few years back someone saying that as old-timer meteorologists who are more attuned to seasonal weather patterns are being replaced by "modern" meteorologists more tied to their computer models, short-term predictions have improved but longer-term predictions may have actually gotten worse.

At the risk of being annoying, I’ll make a challenge: Does anyone know of a weather prediction model that looks more than a month ahead and has been proven valid? (Note: peer review of research is not “proven”; it must be validated with an accepted protocol.)

I found this website helpful for determining future weather trends: http://data1.gfdl.noaa.gov:8380/lasV8/UI.vm
It's possible to zoom in on specific regions and get future weather data of all types. Not sure how easy it will be to convert it into usable EPW. I haven't tried yet.
