ForecastAdvisor.com

ForecastAdvisor.com helps you answer the question “who provides the most accurate weather forecast for my city?”  Using the same data that powers ForecastWatch, ForecastAdvisor provides a convenient overall measure of accuracy for forecasts from AccuWeather, CustomWeather, Intellicast, The National Weather Service, The Weather Channel, and the Weather Underground.

Forecasts that change more over time tend to be less accurate.  ForecastAdvisor lets you see previous forecasts for a coming day, to see if the forecast has changed.  Also, ForecastAdvisor breaks down accuracy statistics in a further analysis page.  You can see how accurate each provider was on high temperatures, low temperature, text forecast precipitation, and icon forecast precipitation, all from one to three days out.

The clean design, limited advertising, and interesting posts on weather forecast accuracy makes ForecastWatch a great place to learn more about weather forecasts and their accuracy.
