If we went with a one point change in the wind, what suggestions would you have as to determining if the wind changes? Would you recommend the same probability as the rules, but with the half change in direction?

Once the wind changes, would a subsequent change in the same direction have a higher probability of occurring, or would you keep the probabilities static? This is assuming each individual change is one point.

What would you recommend for storms?

If it looks like the wind could change, for example when one pulls the first change chit (using the RaW mechanism), is it suggested to announce that a wind change might occur on a subsequent turn? Are wind changes, in realty, a big surprise, or are there small signs of an impending change?
