Year-round US weather: forecast model maps (GFS, ECMWF, HRRR, NBM, GEFS ensemble, AI models), single-site NEXRAD radar, click-anywhere skew-T soundings, global drivers (MJO, Rossby wave train, mountain torque), and an in-house model verified in public against the RTMA analysis. Built directly on NOAA and ECMWF open data.
