Yeah, look at the 2m temp anomaly change from 0z to 12z, lol, on 11/25 over the entire country and Canada. Up to 55F difference in southern Alberta and major differences in Eastern US. Clown range, but still...
18z GEFS maintains that ridge out west from d9-d15, and then relaxes it to more of a zonal flow near the end of the run. But 850s stay in single digits here with most days BN.
I would think that Ida should rank right up there as far as the length of time a hurricane has maintained winds of 100 mph or greater after official landfall. Ida did make landfall in the swampland and marshy areas that would help maintain the winds and storm structure, but just saying.
12 mb pressure fall in last 6 hours, yet despite that rapid deepening the winds remain at 105 mph over that 6 hour period. I know there is usually a lag between the pressure fall and increased wind speed, but this makes little sense. Is it possible that the hunter planes may be missing where the strongest winds are?
The 0z 3k Nam has it bombing to 897 MB by hr 57. That is Cat 5 easily. The setup is very similar to that of Hurricane Camille in 1969, which formed near the Cayman Islands, crossed extreme W Cuba and made landfall on the LA/MS border. Lowest pressure was 900 MB, and winds were estimated at 200 mph after all instruments were blown away.
HWRF shows Cat 3-4 for Louisiana. It was the most accurate on Henri for most of its life.
Euro shows up to 17 inches of rain in 24 hrs in south central TN.
At 11 pm Henri was at 38.6N 71.0W, or precisely where the HWRF had it on their 18z run. Since this model has been the most accurate at every measuring point as was mentioned earlier, I would put the landfall in Newport, RI as the HWRF shows.
