Hi all for those that dont have one, or kno of one, I have found a cool weather app called UAV Forecast in the app store. You set you threshold of wind, height, sats and such and the app checks local conditions and tells you if its safe to fly, check it out

I use this:
Weather Underground

not bad, I like this one cuz you can put in the limits you want to fly in and it tells u if its safe to fly, on my cell its handt
