ForecastWatch is a weather forecast verification and accuracy analysis system that collects over 70,000 weather forecasts per day. The system consists of data capture, verification, aggregation, audit and display components. All components are written in Python. The display component consists of two websites, ForecastWatch.com, the commercial offering, and ForecastAdvisor.com, the free consumer version, both implemented using the Django web application framework. In addition to providing comparative forecast accuracy analysis to commercial weather forecast providers like The Weather Channel, ForecastWatch data and systems have been instrumental in a number of research endeavors. Dr. Eric Bickel, of the University of Texas at Austin, Dr. Bruce Rose of The Weather Channel, and Jungmin Lee of Florida International University have published research using data from ForecastWatch and software written by Intellovations.
