NUCAPS vs. Obs

Perfect conditions to utilize NUCAPS soundings today in the FWD CWA. FWD did a special release at 18z and I was able to compare that to a 19z NUCAPS sounding immediately west of FWD, ahead of the ongoing convection north and west of the CWA. They are remarkably similar from the boundary layer upward with very similar MUCAPE/SBCAPE values around 4600-4800 J/kg.
This highlights how important these NUCAPS soundings can be in the absence of any 18-20z special balloon releases. I'm very impressed with how well it lines up with the observed 18z launch and have more confidence in using these in pre-convective environments.
