High Resolution Rapid Refresh is a really useful mesoscale model for continental US - probably the best out there for this geographic area. 1.65nm (3km) resolution, initialized hourly (vs every 6h for the NAM). Handles seabreezes and land features too. For sailing at least, I'd almost rather have the HRRR than the NAM if I had to choose one of those two. I have to use another mobile app to get the HRRR today. Would rather stay here! Thanks -
