Gridded Forecast Datasets

In the last 10 years, additional gridded forecast products have been developed by the National Weather Service. These gridded products allow forecasters at the NWS to provide specific forecast information every 1.5 miles for a variety of weather elements, such as waves, winds, temperatures, and weather. In turn, graphics such as those below can be generated, allowing customers and partners to get a complete picture of the weather across the Great Lakes.
