A weather radar control system includes a processor configured to acquire first weather data for a first area extending from an aircraft from a weather radar system onboard the aircraft. The first weather data includes a first location of a weather event in the first area. The processor is further configured to receive second weather data for a second area with respect to the aircraft via the communication system from an external location where the second weather data includes a second location of a weather event in the second area, and correlate the first weather data and the second weather data. The processor is further configured to generate display data for display based on the correlated weather data where the display data is for a display area at least partially defined by the first and second areas, and provide the display data to a display system onboard the aircraft.
