@RandyBonnette said in NOAA is about to make some big changes to its global weather model: guys, Here's where you can get more information about FV3-GFS new model: Significant information on the FV3-GFS https://www.emc.ncep.noaa.gov/users/meg/fv3gfs/website and select model (real-time): https://data1.gfdl.noaa.gov/fvGFS/fvGFS_products.php Or find the Pivotalweather portal. You can compare the data there too. Thanks for recommendations
