Abstract: A method for providing weather information to a user is provided. The method includes steps of receiving a gridded forecast and receiving a user request for weather information for a location of interest within the gridded forecast. The method further includes steps of determining if updated sensor data is available for local grid points located proximate the location of interest. If updated sensor data is available, the method updates latest observation-based conditions at the local grid points. The method further includes a step of updating the weather information based on the updated sensor data and the gridded forecast.
