http://www.windguru.cz/ has a strong following. I have been checking the Miami forecast through this site on occasion and found it to be fairly accurate. Thanks to Dave in Jupiter, I now know that you can customize it and have it calculate the forecast for your area. I setup stations around the state but unfortunately, most were mysteriously lost. You can link directly to these locations by entering the username "fksa" and the launch name your interested in. I went back in and did it again resulting in:

Ft. Pierce

I will add more stations around the State again.
I understand that you can apply wind corrections to the forecast to help tune in things to local conditions and variations.
So, please check the forecast in the future and compare it to predicted conditions. If there isn't a location where you please let me know.
