MODEL DATA 

Forecasters use the output from computer models to make their forecasts. Computer models mathematically simulate (or model) the fluid motion of the atmosphere. The output from these models gives the forecaster a picture of how the atmosphere will evolve... For example, how the jet stream will change strength and location, and how surface fronts and low pressure systems will move and change strength. By integrating the latest satellite, radar, and surface observations with the computer model data, the forecaster can evaluate the computer models and adjust the forecast accordingly . The format of most of the data below requires a trained meteorologist to interpret. For information on how well computer models perform, please visit the HPC (Hydrometeorological Prediction Center) web page that summarizes computer model strengths and weaknesses.
