With the GFS tending to under do ridging, and having a solid ridge in place, i dont think that bodes well for the Eastern US

Between 90hrs and 96 hrs, ridge shows it may be starting to break down a little.... Will it be enough?

That’s probably diurnal (day/night) variation.

The 5 day 500mb GFS verification has been quite good the last few days. The Euro, however, has had a nasty habit of over doing ridges.

Euro: https://www.wpc.ncep.noaa.gov/html/ecmw ... op500.html

GFS: https://www.wpc.ncep.noaa.gov/html/gfs0012loop500.html

I don't think anything solid can be determined with these verifications but something to keep in mind.

I wouldn't lay money on the GFS's track, but it's probably depicted weaker than you'd think it would be at 102 hours. Icon ends up hitting Harrison/Jackson Co., MS. We hate South Florida hits here on the central Gulf Coast, because we know it's going to come up later. It's not always for us, but Andrew, Katrina, Betsy, etc. etc. etc.

It found a weakness, moving poleward. Ridging collapses entirely.

Ridge is shrinking, looks like another recurve'ish solution.
