The statement that best describes a major difference in the quality of weather information contained in a daily forecast and a long-range forecast is:
Information contained in a daily forecast is more accurate than the information included in a long-range forecast.
Daily forecasts are based on current atmospheric conditions and have a shorter time frame, making them generally more accurate. Long-range forecasts, on the other hand, are based on models and trends, which can result in less certainty and precision.
