Forecasting
How Meteorologists Predict Weather: Observations, Models, Radar, Satellite, and Experience
How meteorologists make forecasts using observations, computer models, radar, satellite, local knowledge, and communication.
Quick answer: Meteorologists predict weather by combining current observations, physics-based models, radar, satellite, past patterns, and human judgment.
Start with now
Forecasting begins with what the atmosphere is doing right now.
Surface observations, balloons, radar, and satellite help build that picture.
Use models
Computer models simulate the atmosphere forward in time.
Forecasters compare models and adjust for bias, local terrain, and current trends.
Communicate impacts
A useful forecast explains timing, location, confidence, and what people should do.
The final product is both science and communication.
