And the GFS now looks the best at H5 after being the last model to catch on. Model chaos, with too many small disturbances in the same region, difficulty resolving which one will amplify. We know—based on our climo—that baroclincity strongly favors shortwaves that amplify along the SE coast. My read is the GFS could use a “climo correction” or “parameterization” in the eastern CONUS.
Anyway, significant positive changes on the GFS, albeit coming from a very disorganized state. The latest depiction is clearly worth tracking for SE NH.
