The LocalCast model utilizes output from numerical models run by the U.S. National Weather Service and other met services, and develops a consensus of the model input, which is then reviewed and modified by AccuWeather meteorologists. These forecasts are then modified based upon a high-resolution elevation database. The resulting forecast data is geared specifically for surface weather conditions at specific locations.
Local Cast is designed to automatically create animations showing forecasts of temperature, precipitation and other parameters on national, regional or local maps. LocalCast is updated every hour. Once the data is received, it takes only minutes until animations are ready for display.
With LocalCast, television weather presentations can show highly detailed, highly localized information such as animations of temperature forecasts analyzed at one-degree intervals across a DMA, graphs of 15-day local forecasts or the location and forecast evolution of the rain-snow line.
