Comparison of Operational NUCAPS / Modified NUCAPS

Modified NUCAPS sounding for Bienville county in SHV CWA in advance of line we have severe warnings out for with embedded tornadic circulations.

Comparison of NUCAPS soundings in pre-storm environment in SHV CWA. We’re warning for a bowing segment line with bookend vortices. There are several important differences between the generated soundings, including a better representative moisture profile from the modified sounding given the moist environment, linear convection, precip. loading processes. Also of note is the inversion shown between 900 and 850mb in the operational sounding. Analysis of the RAP13 850 temp fields suggest the modified sounding is more representative of what’s likely occurring. In this instance the NUCAPS modified sounding appears to be a better product for the current environment.
