Distributed Hourly Wind Data

I am going to poll my readers for help on a problem. I am trying to find meteorological data for wind speed from a number of geographically separated weather stations. By geographically separated I mean, on the scale of Texas or Ontario. I need the data to be measured hourly or faster. The data needs to be in some reasonable downloadable format so that I can parse it without too many difficulties.

Thus far, most of the data I've found is proprietary and people want me to pay for it. Since I don't make any money writing this blog, I'm not willing to do that. The only source of decent free data I've found is from the University of Waterloo.
