What altitude range does the U.S. High-Level Significant Weather Prognostic Chart cover?

The U.S. High-Level Significant Weather Prognostic Chart is specifically designed to provide information regarding significant weather conditions at higher altitudes, particularly between 24,000 feet and 63,000 feet. This range is crucial for pilots who operate at altitudes where significant weather phenomena, such as thunderstorms, jet streams, and turbulence, can have a major impact on flight safety and performance.

Pilots rely on this chart for planning purposes, ensuring they are aware of potential weather hazards that could affect their aircraft's operation in the stratosphere and upper troposphere. Understanding this altitude range is vital for navigational decisions and optimizing flight routes to avoid adverse weather conditions, making it a critical tool in high-altitude flight operations.
