Displaying weather-based information for a flight path is disclosed. A data processing system receives a flight path and retrieves weather-related raster-based forecast data along the flight path. The data processing system then generates a vertical profile for the flight path for all altitudes along the flight path and all flight times along the flight path. The weather-related raster-based forecast data is then converted by the system into polygonal bands that are superimposed by the data processing system onto the vertical profile, resulting in a modified vertical profile. The modified vertical profile is then displayed by the data processing system with a selector in a graphical user interface (GUI) for selecting a flight time of the flight times along the flight path.
