A method of displaying a weather condition indicator with respect to an aircraft includes receiving weather data from a weather radar system. The weather data includes data indicative of a first location of the weather condition. The method also includes determining a second location of the weather condition based on data indicative of a movement of the weather condition, and displaying the weather condition indicator with reference to the second location.
