Hello ! We have built a high volume weather data service called https://www.weatherbit.io. We have JSON API's for 16 days/5 day/ 24 hour forecasts for any point on the globe. Along with hourly historical observations going back 5 years. We also have a generous free tier if anyone is interested in trying it out. The Free tier allows up to 45 calls per minute. Yes, you can really make 64,000 calls per day on the free tier without us batting an eye . Our historical data is backfilled, and quality controlled. We have data for over 28,000 stations, and allow geographic based searches via the API (along with bulk requests). We currently support JSON, and JSONP. Check us out here -> https://www.weatherbit.io Thanks!
