Gridded Forecast Datasets

Over the past 7 years, additional gridded forecast products have been developed by the National Weather Service. These gridded products allow forecasters at the NWS to give a 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 to allow customers and partners to get a complete picture of the weather across the Great Lakes.
