First try at comparing modified soundings.

1. 12Z Midland RAOB modified to 30/18, yielding 4250 SBCAPE (3800 with ob at time of earlier NUCAPS)

2. Afternoon NUCAPS nearest LBB (designated CWA today) modified to 26/19, yielding 3900 SBCAPE.

LBB is appx 125 mi N of MAF, but in reasonably similar environment.  Despite other differences, feature at 700 mb appears in both.

3.  Next, NUCAPS afternoon sounding nearest MAF (in relatively cloudless area).  Not modified.

4.  And finally, for comparison, the observed 0Z sounding at KMAF.
SBCAPE at 4200.  The drying of the air at 600-800 mb since 12Z is reflected by intermediate NUCAPS soundings.
