I use this:
http://shiftyjelly.com/Pocket_Weather.htmlbut with a tagline like "Because you live in Australia not America" it's pretty clear to see that it's for Australia only. There may be something similar for USA, but it'll give you an idea of what could be available.
Not sure if you have anything like it over there, but the most popular site in Australia is SeaBreeze.
This is my homepage:
http://www.seabreeze.com.au/graphs/qld.aspGives me real time info about swells and more importantly, wind. The list of sites on that particular page gives me a good idea of what is happening up and down the most local parts of the coast, to where I sail.
Even better, the place I launch from has a webcam so I can see if it's flat or white-cappy, too busy, or even if there's gonna be someone to race when I get there!
http://www.hyc.net.au/webcam.htmThe webcam is provided by the Brisbane Storm Chasers website, so it's a bit of a "scratch my back" deal, as far as I can guess.
This "Yacht" Club is only about 15 minutes from me and located at a public boat ramp. It's really great knowing what to expect before I leave the house. It may be worth putting the idea forward to your local sailing club and see if they'll consider it.
Can't hurt to try...
