Not sure about the longer range as I feel we
may be close to hitting chaos, but probability forecasts will undoubtedly
improve.

Not according to something I read recently. If you had perfect models, chaos
would show itself as an exponential deviation from the forecast with time.
At the moment, the deviation is fairly linear. So we should be able to tell
when we are approaching the chaos limit, and it's not yet.
