About weather in Herndon

The weather forecast for Herndon is based on a comprehensive analysis of the results of several hydrodynamic models of the atmosphere. Each model forecast is taken into account with the necessary weight to achieve maximum accuracy of the result. A number of additional meteorological parameters are calculated using unique author methods. In addition, to refine forecasts in Herndon for today and tomorrow a special short range correction mechanism is used, so the quality of today, tomorrow and 1 - 3 days predictions is usually higher than for 5 days or a week 5-7 days. Due to some modern atmospheric model limitations, 10 day and 14 day weather forecasts for Herndon usually have lower accuracy, so they can only be used for evaluation purposes.
