About

Forecast Scoreboard compares the National Weather Service and weather models. It is independent. Write to [email protected].

Forecast Scoreboard publishes ranks of weather forecasts against the weather that later happened. A smaller miss ranks higher. The National Weather Service is the baseline on the daily boards. Hurricane pages compare model tracks and intensity with the National Hurricane Center best track. Television stations are not graded. A meteorologist is scored only after they opt in, on public forecasts they post or share.

Data sources

Hurricane scores use National Hurricane Center a-decks and b-decks. Current storms come from the operational files. The archive uses the archived a-deck and best track for past Atlantic seasons. The post-season HURDAT2 file is not loaded. Google DeepMind and WeatherNext 3 are ensemble-mean tracks from Weather Lab. ECMWF AIFS, ECMWF HRES, and the ECMWF ENS mean are ECMWF open-data cyclone tracks. AI GFS is NOAA’s AIGFS tracker. A model with no stored forecast on a storm has no score there.

Daily temperature scores use National Weather Service forecasts, GFS, and the other models on the board, checked at one official airport climate site in each market. Collection of those forecasts started September 26, 2026. Flood and storm-report maps use National Weather Service local storm reports and flash flood warnings.

The world leaderboard scores ECMWF IFS, ECMWF AIFS, GFS, and Canadian GEM at 50 major cities against routine METARs at each city's main airport. Canadian GEM is the MSC GDPS from the MSC Datamart. That record starts when collection starts. It does not replace the US market pages.

Independence

Nobody pays for a place on a list. Forecast Scoreboard is not affiliated with the National Weather Service, NOAA, the National Hurricane Center, Google, ECMWF, or any television station.
