s3research predictor updated.
Just wanted to let everyone know that I have updated my flight prediction tools to use the new GFS Version 15 (FV3-based) weather model. The oldest weather file you can use is 2019061212. The earlier ones are no longer supported by the too.
HABHUB is still using the 06 prediction so I don't know if they have the support in place or not.
