All model nowcast and forecast information is based on a hydrodynamic model and should be considered as computer-generated nowcast and forecast guidance.
Surface Wind Forecast Guidance
This wind animation depicts forecasted hourly surface (33 ft [10m] above the water) winds for the next 30 hours. The hourly wind fields were created by spatially and temporally interpolating wind forecast guidance from the latest run of the National Weather Service's operational North American Mesoscale (NAM) weather forecast model, or gridded forecasts from NWS field offices. The original spatial and temporal resolutions of the NAM wind forecast was 7.5 miles (12 km) and 3 hours, respectively. These interpolated wind fields were used by a hydrodynamic forecast model to generate oceanographic forecasts for the Lake out to 30 hours.
