We really need those recon missions into 92L

Several 0z hurricane models blow the Invest up while in the Gulf, but then dry air and shear takes their toll on the cyclone by the time it is nearing the coast, and unlike Edouard which was intensifying into landfall, 92L - then Isaias - weakens dramatically into landfall. Side rant ~ If this were to actually happen, we could in theory have a Major in the Gulf, watches and warnings put up along the northern Gulf coast and official forecasts from NHC calling for weakening by landfall, but with people frantically checking the latest clickbait worst-case runs on social media and freaking out. Then blame the NHC of course should Isaias roll onshore more like a wet lamb after social media posts roared like a fierce lion.

Other models, including the operationally retired HWRF, maintain a vigorous Major all the way into landfall.

Recon ASAP is going to be critical in nailing this forecast with enough time.

Here are some heading-into-landfall forecasts from the hurricane models

Reassuring that the HWRF is now often thought of as more of a C-tier model, replaced and bested by the HAFS. Still, a model run that deserves consideration until proven otherwise.
