The recent study by Kantar gathered, analyzed and compared the on-air televised weather forecast presentations of KGPE, KMPH and KSEE local stations with the AccuWeather forecast on KFSN to determine which had the most accurate forecast.
For maximum consistency, the 6 pm local time, Monday to Friday, on-air TV weathercast, which most stations provide, was viewed, and the forecast from this telecast was recorded and compared and the results verified.
Forecasts were verified by comparing them to observed data from US National Weather Service official data sources. For a complete glossary of all terms, calculations and data sources see Appendix A and Appendix B.
