These maps show forecasts of Rain on Snow (ROS) Terrestrial Water Input (TWI) potential for the state of Nevada. Values range from zero (no potential) to six (high potential) and are based on the decision support thresholds described in Chapter 5 of Heggli (2023). Values are generated using daily-scale snow water equivalent and snow depth values from SNODAS at a 1km resolution. The snow information is paired with North American Mesoscale (NAM) Conterminous United States (CONUS) model forecasts of temperature and precipitation available at a 3km resolution. The ten maps shown represent six hourly forecasts of ROS TWI potential for 60 hours into the future and are updated upon the completion of the NAM's 4x daily forecast cycles initiated at 00UTC (5pm LST), 06UTC (11pm LST), 12UTC (5am LST), and 18UTC (11am LST). The forecasts assume that the state of the snowpack, as obtained from the daily SNODAS download, remains constant throughout the 60 hours of forecast.

These forecasts are based upon experimental research in order to provide timely science to the public.
