Maybe the NHC disregarded the NEXRAD signatures during Sally because those features were short-lived and related to mesoscale dynamics...?
They mentioned this explicitly in the TCR for Isaias, that they disregarded the 117 kt FL wind since they didn't believe that was representative of the overall wind field that they were finding.
While there was one flight-level wind observation of 117 kt, this observation appears to be a singular spike, possibly in a meso-vortex sampled around that same time and is not considered
representative of Isaias’ intensity.
There is no such disclaimer in the Sally TCR concerning the WSR-88D bin velocities, which indicates the WSR-88D bin velocities played no role in the final assessment for the max wind speed. As a result, the NHC didn't determine if those bin velocities were related to more mesoscale features or not.
