What do short-range surface prognostic charts provide?

• A. Forecast of surface pressure systems, fronts and precipitation for a two day period; forecast area covers the 48 contiguous United States, coastal waters and portions of adjacent countries; four forecast periods: 12, 24, 36, and 48 hours.
• B. A forecast of turbulence in the upper atmosphere for the next 6 hours.
• C. A list of airports and runways.
• D. A forecast of icing.

Answer: (A)

Short-range surface prognostic charts are used to visualize forecasted surface weather features over the next two days. They depict surface pressure systems, fronts, and areas of precipitation, with valid times at 12, 24, 36, and 48 hours. The charts cover the contiguous United States, coastal waters, and nearby areas. This helps you anticipate frontal passages and precipitation along a flight path so you can plan routes and altitudes accordingly. They don’t show upper-level turbulence, airport/runway details, or icing, which come from different charts.
